| dc.description.abstract1 | BACKGROUND: The inhibition of the enzyme telomerase (TERT) has been widely investigated as a new pharmacological
approach for cancer treatment, but its real potential and the biochemical consequences are not totally understood.
OBJECTIVE: Here, we investigated the effects of the telomerase inhibitor MST-312 on a human glioma cell line after both
short- and long-term (290 days) treatments.
METHODS: Effects on cell growth, viability, cell cycle, morphology, cell death and genes expression were assessed.
RESULTS: We found that short-term treatment promoted cell cycle arrest followed by apoptosis. Importantly, cells with
telomerase knock-down revealed that the toxic effects of MST-312 are partially TERT dependent. In contrast, although the
long-term treatment decreased cell proliferation at first, it also caused adaptations potentially related to treatment resistance
and tumor aggressiveness after long time of exposition.
CONCLUSIONS: Despite the short-term effects of telomerase inhibition not being due to telomere erosion, they are at
least partially related to the enzyme inhibition, which may represent an important strategy to pave the way for tumor growth
control, especially through modulation of the non-canonical functions of telomerase. On the other hand, long-term exposure
to the inhibitor had the potential to induce cell adaptations with possible negative clinical implications. | pt_BR |
