Abstract
Aberrant mucin-type O-glycosylation by glycosyltransferases is a well-described hallmark of many cancers and is also associated with additional non-cancerous developmental and metabolic disorders. The current review focuses on N-acetylgalactosaminyltransferase genes (GALNT) and proteins (GalNAcTs) to illustrate their importance in cancer biology. Aberrant O-glycosylation by GalNAcTs activates a wide range of proteins that carry out interactions of sessile and motile cells affecting organogenesis, responses to agonists and stimulating hyperproliferation and metastatisation of neoplastic cells. As genome-wide analyses have provided abundant clues regarding under- or over-expressed genes that characterize different types of cancers, GALNTs and their transferase products have attracted attention by being unexpected actors in neoplastic contexts. We intend to review the current knowledge on GALNTs and their encoded transferases in cancer and suggest what could be the significance of such information in cancer pathogenesis and management.

In-vitro Interaction of αB-Crystallin on Serum Amyloid A and Serum Amyloid A ...theijes
The interactions of SAA and SAA protofibrils with protecting role of alphaB-Crystallin with hepta 1-6 cells of the mouse are dealt with in detail to study the binding of SAA protofibrils in various conditions. Specifically, interaction of serum amyloid A fibrils with a cell surface binding site/receptor might alter the local environment to cause cellular dysfunction and to be more favorable for amyloid formation and prevention with alphaB-Crystallin. This is important in relation to the activity of membrane proteins, because losing the activity of such systems will ultimately lead to malfunction or death of the cell. The interactions of Serum Amyloid A (SAA) and Serum Amyloid A protofibrils with hepta 1-6 cells of the mouse are dealt with in detail to study the binding of SAA protofibrils in various onditions. The induced fluorescence, induced circular dichroism, FACScan and MTT assay results have shown the SAA and SAA prototfibrils binding and cell toxicity with the hepta 1-6 cells with different concentrations of alphaB-Crystallin 0.15-15 nM. Specifically, cells were incubated with 1.25-6.25 M SAA-FITC and SAA protofibrils-FITC assayed. The 50% viable hepta 1-6 cells at 4–6 M with an LD50 of 3.5 M. The interaction of serum amyloid A fibrils with a cell surface binding site/receptor might alter the local environment to cause cellular dysfunction and to be more favorable for amyloid formation. In the present study, concluding that the SAA fibrils and SAA protein binding and cell cytotoxicity was reduced in the presence of alphaB-Crystallin.

N-glycosylation of ICAM-2 is required for ICAM-2- mediated complete suppressi...Enrique Moreno Gonzalez
Cell adhesion molecules (CAMs) are expressed ubiquitously. Each of the four families of CAMs is comprised of glycosylated, membrane-bound proteins that participate in multiple cellular processes including cell-cell communication, cell motility, inside-out and outside-in
signaling, tumorigenesis, angiogenesis and metastasis. Intercellular adhesion molecule-2 (ICAM-2), a member of the immunoglobulin superfamily of CAMs, has six N-linked glycosylation sites at amino acids (asparagines) 47, 82, 105, 153, 178 and 187. Recently, we demonstrated a previously unknown function for ICAM-2 in tumor cells. We showed that ICAM-2 suppressed neuroblastoma cell motility and growth in soft agar, and induced a juxtamembrane distribution of F-actin in vitro. We also showed that ICAM-2 completely suppressed development of disseminated tumors in vivo in a murine model of metastatic NB.
These effects of ICAM-2 on NB cell phenotype in vitro and in vivo depended on the interaction of ICAM-2 with the cytoskeletal linker protein α-actinin. Interestingly, ICAM-2
did not suppress subcutaneous growth of tumors in mice, suggesting that ICAM-2 affects the metastatic but not the tumorigenic potential of NB cells. The goal of the study presented here was to determine if the glycosylation status of ICAM-2 influenced its function in neuroblastoma cells.

71st ICREA Colloquium "Intrinsically disordered proteins (id ps) the challeng...ICREA
The unbearable lightness of being (a protein)
Proteins adopt beautiful shapes that enable them to perform an incredible array of tasks. But these wiggly little creatures cannot stay still. Is this a nuisance or a blessing?
After a basic introduction to proteins, Xavier Barril focuses on the implications of protein flexibility for drug discovery. Showing that a rigid representation has been, and continues to be, extremely useful. He will present some of the failures and challenges in introducing a more realistic view, but also how the dynamic perspective is gaining ground thanks to the advances in structural biology and computational chemistry.
Xavier Salvatella discusses where the limit is: can proteins be completely disorganised? Can we study and understand intrinsically disordered proteins from a structural point of view? How can this class proteins perform functions if they have no structure? Why have they evolved? Is it ever going to be possible to modify the function of this class of proteins with small molecules, as we have learned to do with proteins that fold?

Replisome-Cohesin Interfacing A Molecular Perspective.pdfAtiaGohar1
Cohesion is established in S-phase through the action of key replisome
factors as replication forks engage cohesin molecules. By holding sister
chromatids together, cohesion critically assists both an equal segregation of
the duplicated genetic material and an efficient repair of DNA breaks.
Nonetheless, the molecular events leading the entrapment of nascent
chromatids by cohesin during replication are only beginning to be
understood. The authors describe here the essential structural features of
the cohesin complex in connection to its ability to associate DNA molecules
and review the current knowledge on the architectural-functional organization
of the eukaryotic replisome, significantly advanced by recent biochemical
and structural studies. In light of this novel insight, the authors discuss
the mechanisms proposed to assist interfacing of replisomes with chromatin-
bound cohesin complexes and elaborate on models for nascent
chromatids entrapment by cohesin in the environment of the replication
fork.
