The document discusses several topics related to DNA repair, cancer, and menopause. It describes how the p73 protein is involved in DNA repair and may help combat esophageal cancer. It also discusses how new loci linked to age of menopause onset are involved in DNA repair and immune processes, which could help reduce menopause side effects and diseases like breast cancer. Overall, the document highlights the potential benefits of further research on DNA repair mechanisms for reducing cancer rates and alleviating menopause symptoms.
DNA Repair Mechanisms Reduce Cancer and Menopause Effects

4. The DNA containing
the genetic instructions used in the
development and functioning of all
known living organisms. DNA has
two processes
• DNA replication is a biological
process that occurs in all living
organisms and copies their DNA.
• DNA repair refers to a collection of
processes by which a cell identifies
and corrects damage to the DNA
molecules that encode. its genome.

6. Esophageal cancer is usually
begins in the cells that line the
inside of the esophagus.
Esophageal cancer can occur
anywhere along the esophagus,
but it occurs most often in the
lower portion of the esophagus.
More men than women get
esophageal cancer.

7. Dysphagia and odynophagia are the
most common symptoms of
esophageal cancer. Dysphagia is the
first symptom in most patients.
Odynophagia may also be present.
Fluids and soft foods are usually
tolerated, while hard or bulky
substances (such as bread or meat)
cause much more difficulty.

8. p73 is a protein related to the p53
tumor protein, it has been considered
a tumor suppressor, also this gen It is
involved in cell cycle regulation, and
induction of apoptosis.
The p73 gene encodes a protein with
a significant sequence homology and
a functional similarity with the tumor
suppressor p53. The over-expression
of p73 in cultured cells promotes a
growth arrest and/or apoptosis
similarly to p53.

9. I think that the development of
this techniques (the use of the
gen p73) is a good advance in
medicine and a new opportunity
to heal the cancer, because this

11. • The menopause is formally
medically defined as the time of
the last menstrual period (or
menstrual flow of any amount,
however small).
• The transition from reproductive
to non-reproductive is the result
of a reduction in female hormonal
production by the ovaries.
• The menopause transition, and
postmenopause itself, is a natural Taken from: http://www.healblog.net/health-

life change, not a disease state or
a disorder.
12. The new loci contained
candidate genes involved in
DNA repair and immune
function. Pathway analyses
indicated that biological
processes associated with
these loci were
exodeoxyribonuclease, NFκB
signaling, and mitochondrial
dysfunction.

13. Menopause is based on the natural or
surgical cessation of estradiol and
progesterone production by the ovaries,
which are a part of the body's endocrine
system of hormone production, in this case
the hormones which make reproduction
possible and influence sexual behavior.
Common symptoms are:
Hot Flashes
Night Sweats

14. After reading this new, I recognize
the importance of the menopause
phenomenon like a biological
change in the woman that can
open the door to a body´s health
decrease, accelerating the aging
of the senses. In that way, a closer
study of loci focused in age of
menopause, will bring welfare for
the woman all over the
world, because this loci it´s related
to multiple diseases that are very
common and significant in the
females population and their
family.

mechanisms is very promising to
reduce the incidence of cancer and
in the menopause process.
