New target to enhance anti-cancer drug sensitivity found in translation

Several times i have discussed the the topic of anti-cancer targets, Novel Enzyme Inhibitor Paves Way for New Cancer Drug: Agent Proves Effective Against Melanoma Cells; Researchers Find that a Small Molecule Can Activate an Important Cancer Suppressor Gene. The development of resistance to anticancer chemotherapeutic agents remains a large problem. In some cases, such resistance is associated with altered control of a cellular process known as translation, which is central to the generation of proteins. New data, generated by Jerry Pelletier and colleagues, at McGill University, Montreal, have identified a drug that can enhance the sensitivity of mouse cancer cells to standard anticancer chemotherapeutic agents. In the study, small molecules were screened for their ability to inhibit the initiation of translation by modifying the function of a protein known as eIF4A, which has a central role in translation initiation. A class of natural drugs known as cyclopenta[b]benzofuran flavaglines were found to have the desired effects and one member of this class of compounds was shown to reverse the resistance of cancer cells to anticancer chemotherapeutic agents in a mouse model of lymphoma. The authors therefore suggest that developing approaches to inhibit translation initiation by targeting eIF4A might provide a way to altering drug resistance in cancers exhibiting altered control of translation initiation.

Life Science and Informatics

What is this?
is this a new industry?
or a old wine in a new bottle?

Well Life Sciences and Informatics can be anything form computational biology, all omes and omics, core bioinformatics to curation and literature mining, database creation, in the area of biology, chemistry , bio-chem space.

There are number of companies in India and bangalore is the forefront as a major bio-cluster with 20 to 30 companies in this sphere.

now how good are these companies doing?
how good are they in terms of the international markets and how profitable is their business?
what do they do?
their clients?

These are some interesting things that could be discussed in this blog page...
