Role of hnRNP A/Bs in the regulation of telomerase and telomere maintenance.

Functional telomeres protect chromosomal ends from DNA degradation and unwantedrecombination, and are known to play an important role in cellular senescence. While telomerase and telomere-associated proteins are known to involve in the maintenance of functional telomeres, little is known if heterogeneous ribonucleoproteins (hnRNPs) may function in telomere maintenance. We have shown recently that hnRNPs are the most abundant proteins in the nuclear extracts that bound specifically to G-strand telomeric DNA. The findings that many of these hnRNPs inhibits telomerase in vitro and the fact that hnRNPs are integral components of the nuclear matrix suggest that hnRNPs can participate in the control of telomerase activity and in telomere maintenance in vivo. Currently, we are investigating the biological role of hnRNP A/Bs in the control of telomerase activity and telomere length maintenance in human cells.
