1. MicroRNAs are small non-coding RNA molecules that regulate gene expression at the post-transcriptional level. They play important roles in skin biology and diseases. 2. Specific microRNAs like miR-203, miR-146a and miR-125b are involved in the pathogenesis of psoriasis by regulating inflammatory signaling pathways. 3. MicroRNAs also modulate processes like wound healing, angiogenesis, and skin cancer development by targeting genes involved in these processes. Dysregulation of microRNAs has been observed in melanoma and other skin malignancies.

Gene therapy.. Dr.Padmesh
Gene therapy involves introducing functional genes into patients to treat diseases. It has three main steps: identifying the defective gene, cloning the normal gene, and inserting the normal gene into target cells. There are two main approaches - ex vivo, where cells are removed and modified before being returned, and in vivo, where genes are directly inserted. Gene therapy aims to either augment gene function for loss of function mutations or inhibit gene expression for negative dominant mutations. While promising results have been seen for some diseases, risks still include immune reactions and insertional mutagenesis.
Gene therapy
Gene therapy involves delivering genes to correct genetic abnormalities. The first successful gene therapy treated a girl with severe combined immunodeficiency. Gene therapy can replace, deactivate, introduce, or enhance genes to treat diseases. Viral and non-viral vectors are used to deliver genes. While gene therapy has treated some genetic diseases and cancers, it remains imperfect as many diseases involve multiple genes and genes can be difficult to target precisely without risks.
Gene therapy
Gene therapy involves introducing genes into cells to treat disease. It can be used for both somatic and germ line cells. Viruses are often used as vectors to deliver therapeutic genes. Gene therapy for diabetes may involve transplanting genetically modified islet cells to produce insulin in response to blood glucose levels, inducing tolerance to one's own islet cells to prevent autoimmune destruction, or adding genes to increase islet cell survival. The goals are to maintain normal blood glucose levels regardless of diet and provide an unlimited source of insulin-producing cells.
Gene therapy ex vivo method
This document discusses ex vivo gene therapy methods. It involves 3 main steps:
1) Isolation of cells from a patient with a genetic defect
2) Culturing and genetically modifying the cells to correct the defect
3) Transplanting the modified cells back into the patient. As the patient's own cells are used, there is no risk of immune rejection. Viral and non-viral vectors are used to deliver therapeutic genes to the cultured cells. Ex vivo gene therapy is applicable to tissues that can be removed, modified and reintroduced into the body.
Human gene therapy
Gene Therapy, Somatic cell gene therapy, germ line gene therapy, classical gene therapy, non-classical gene therapy, targets of gene therapy, barriers of gene therapy, ex vivo gene therapy, in vivo gene therapy, vectors for gene delivery, antisense therapy
15 Therapy Of Genetics Diseases
This document discusses various approaches for therapy of genetic diseases, including conventional and gene therapy approaches. Conventional approaches include dietary therapy, protein/enzyme replacement, pharmacal therapy, and surgery. Gene therapy involves the deliberate introduction of genetic material into human cells for therapeutic purposes, and can be done through somatic or germline cell gene therapy, as well as ex vivo or in vivo approaches. Viral vectors are commonly used to deliver the therapeutic gene to target cells.

Gene therapy
Gene therapy involves inserting genes into cells to prevent, alleviate or cure diseases caused by genetic defects. There are two main types of gene therapy - somatic cell gene therapy, which targets non-reproductive cells, and germline cell gene therapy, which targets reproductive cells and can be inherited. There are two main approaches - ex vivo gene therapy, where cells are modified outside the body, and in vivo gene therapy, where genes are modified inside the body. Viral and non-viral vectors are used to deliver genes to cells. Gene therapy has shown promise in treating diseases like SCID, cystic fibrosis, and cancer. While theoretically a permanent cure, gene therapy still faces challenges and high costs that limit widespread use.

Gene therapy
The sequencing of the human genome has been compared to putting a man on the moon, and it will certainly change health care, but the most important work lies ahead, in determining how to put the information to medical use. In this context, applications such as gene therapy are being explored. What was once seen as a science fiction dream is now becoming a real possibility.
Gene therapy is a new form of drug delivery that leads the patient's own cells to produce a therapeutic agent. It could potentially eliminate the need for repeated administration of proteins or drugs. Applications of gene therapy not only include rare inherited diseases but extend to common acquired disorders, including tumours (predominantly malignant melanoma) and haematological disorders, cardiovascular disease, and the acquired immunodeficiency syndrome. Gene therapy therefore could be a key element of medical practice in the future. Gene therapy is the insertion of genes into an individual's cells and tissues to treat a disease, and hereditary diseases in which a defective mutant allele is replaced with a functional one. Although the technology is still in its infancy, it has been used with some success. Antisense therapy is not strictly a form of gene therapy, but is a genetically-mediated therapy and is often considered together with other methods.

INTRODUCTION,HISTORY,TYPES, USES, ADVANTAGES, DISADVANTAGES, DRAWBACKS, GENETIC ENGINEERING,REGULATION
Basics of gene therapy
This document discusses gene therapy, including its history, mechanisms, applications, and challenges. It begins by defining genes and their role in hereditary traits. It then explains how gene therapy works by inserting genes into cells to treat genetic diseases. Various gene therapy methods are outlined such as ex vivo therapy using cultured cells and in vivo direct delivery. Challenges including short duration of effects, immune responses, and safety issues from viral vectors are also summarized.
Gene therapy and gene delivery systems
Genes carry hereditary information and encode proteins. Gene therapy aims to treat diseases by correcting defective genes through various approaches like inserting a normal gene or repairing an abnormal gene. Early research in the 1980s involved inserting human genes into bacteria. The first human gene therapy treated a girl for SCID in 1990 by inserting a normal gene into her white blood cells. Viral vectors like retroviruses and adenoviruses as well as non-viral methods can deliver genes, but all methods face challenges like short-lived effects, immune responses, and difficulties treating multi-gene disorders and diseases. While progress has been made, setbacks include a death in 1999 from an immune response and some children developing cancer from viral vectors.

While promising, gene therapy still faces challenges like improving delivery methods and reducing immune responses.
Superbug Infection | Dr Jose Poulose
This document discusses "superbugs", which are bacteria that are resistant to antibiotics known as Carbapenem Resistant Enterobacteriaceae (CRE). Two deaths at a California medical center were linked to CRE after patients were exposed via contaminated medical instruments. CRE infections cause thousands of cases and deaths annually in the US. They are difficult to treat as the bacteria have become resistant to most available antibiotics. Prevention through hygienic practices by healthcare workers and attention to sterilizing instruments is important to avoid CRE becoming a widespread epidemic.
NDM-1 SUPERBUG
The document discusses the NDM-1 superbug, a gene carried by some bacteria that makes them resistant to nearly all antibiotics. The gene encodes for the enzyme New Delhi metallo-beta-lactamase 1 (NDM-1) which breaks down carbapenem antibiotics. It was first discovered in a Swedish patient who had undergone surgery in India. The gene can be transferred between bacteria via small circles of DNA called plasmids, even between unrelated bacterial strains. This makes treatment very challenging as it can spread rapidly between different disease-causing bacteria. Prevention requires responsible antibiotic use and hygiene practices to limit the spread of resistant infections.

This document discusses gene therapy and genetic engineering. It distinguishes between gene therapy, which aims to treat disease by replacing mutated genes, and genetic enhancement, which aims to modify humans in a way that goes beyond curing illness or disability. While gene therapy seeks to cure disease and is considered acceptable, genetic enhancement that modifies humans to make them "super human" raises ethical issues and is generally not supported by the Catholic Church. The key distinction is that gene therapy should be therapeutic and only done to promote health, while genetic enhancement goes beyond therapy and could worsen conditions or unfairly advantage some individuals.

Researchers are studying gene therapy for a number of diseases, such as severe combined immuno-deficiencies, hemophilia, Parkinson's disease, cancer and even HIV, through a number of different approaches (see video: 'Gene Therapy a new tool to cure human diseases'). A gene can be delivered to a cell using a carrier known as a “vector.” The most common types of vectors used in gene therapy are viruses. The viruses used in gene therapy are altered to make them safe, although some risks still exist with gene therapy. The technology is still in its infancy, but it has been used with some success.
Gene therapy
Gene therapy involves modifying genes to treat or cure disease. It works by replacing mutated genes, inactivating abnormal genes, or introducing new genes. Early successes treated immune deficiencies, but challenges remain in achieving long-term effects without side effects. Promising areas are treating inherited retinal diseases and Parkinson's through localized delivery of therapeutic genes using viral or non-viral vectors. While offering potential cures, gene therapy also raises ethical issues that require ongoing discussion.

Gene therapy
The document discusses gene therapy and its potential to treat genetic diseases. It describes how gene therapy works by introducing functional genes into cells to replace defective genes causing disease. The first approved gene therapy treated a girl with ADA-SCID by inserting a functional ADA gene. While promising, gene therapy faces challenges like short-lived effects and safety issues that must still be addressed.
Gene Therapy;Boon Or Adversary To Humanity
Gene therapy involves introducing normal genes into patients to compensate for mutated genes that cause disease. It works by using a vector to deliver the therapeutic gene into a target cell, allowing functional proteins to be produced and returning the cell to a normal state. There are two main types - germline gene therapy, which can pass therapeutic effects to future generations, and somatic gene therapy, which only affects the individual patient. While initial gene therapy trials showed promise, there have also been safety issues, as in 1999 a patient died due to an immune response to the adenovirus vector. Researchers continue working to address risks before conducting further human clinical trials.

Gene therapy involves introducing genes into cells to treat disease. It works by correcting defective genes that cause diseases. The first approved gene therapy occurred in 1990 when a child with ADA-SCID was treated. There are two main types of gene therapy - somatic cell therapy targets body cells while germline therapy affects eggs and sperm. Significant challenges remain for gene therapy including developing safe methods for long-term effects and ensuring equitable access to new treatments. However, gene therapy has potential to cure many inherited diseases and revolutionize medicine.

Gene therapy
Gene therapy involves introducing genes into cells to treat or prevent disease. It works by correcting defective genes that cause disease or by making cells produce products to treat the disease. The first approved gene therapy treated a girl for ADA-SCID. There are two main approaches - in vivo therapy directly delivers genes into body cells, while ex vivo therapy transfers genes to cultured cells before reinsertion. Viral vectors like retroviruses and adenoviruses are often used due to their ability to deliver genes, but come with risks like insertional mutagenesis. Non-viral methods include physical methods like microinjection and chemical methods using liposomes. Gene therapy shows promise for diseases like cancer, cardiovascular disease, and neurological disorders.
Gene therapy
Gene therapy involves inserting normal genes into cells to treat genetic diseases. The first successful gene therapy trial treated a patient with severe combined immunodeficiency (SCID) caused by adenosine deaminase (ADA) deficiency. The procedure involved removing the patient's lymphocytes, infecting them with a retrovirus carrying the normal ADA gene, allowing the gene to integrate and express ADA, and returning the modified lymphocytes to the patient to permanently produce the enzyme. This landmark trial established gene therapy as a viable treatment approach for genetic diseases.
GENE THERAPY AND GENE DELIVERY SYSTEMS GROUP 5.pptx
Genes are the basic units of heredity that encode proteins. Gene therapy aims to treat diseases by correcting defective genes. There are several approaches, including inserting a normal gene to replace a faulty one. Gene therapy can be somatic, only affecting the individual, or germline, making the effects heritable. Vectors like viruses are used to deliver therapeutic genes to target cells. Common types are adenoviruses, retroviruses, and AAVs. Gene therapy holds promise for treating many genetic disorders and diseases like cancer.
Gene therapy
This document discusses components of a gene therapy strategy for cancer treatment. It describes introducing exogenous DNA into cancer cells to alter gene expression and phenotype. There are two main aims - replacing defective tumor suppressor genes or introducing genes to kill cancer cells. Delivery methods include viral vectors, physical methods like injection, and chemical methods using liposomes. The document also discusses targeting tumor cells or normal cells like stem cells, using suicide genes or gene replacement, and overcoming challenges of systemic delivery.
Cancer Gene therapy
Gene therapy aims to alter the phenotype of diseased cells by introducing exogenous nucleic acids like DNA. It involves choosing a cellular target, effector mechanism, delivery method, and effector gene. For cancer, common targets are tumor cells themselves or normal cells like stem cells. Effector mechanisms include gene replacement, suicide genes, and RNA-directed strategies. Delivery can be viral, non-viral, or involve artificial virus-like particles. Effector genes, promoters, and suicide genes must be chosen to match the intended target and effect. Some gene therapy strategies have shown effectiveness in clinical trials for cancers like breast and prostate.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
