US 6,686,159 B2 · Methods and compositions for modulating telomerase reverse transcriptase (TERT) expression

Abstract

Methods and compositions are provided for modulating, and generally upregulating, the expression of telomerase reverse transcriptase (TERT) by blocking repression of TERT transcription, e.g., by inhibiting binding of repressor factor to a Site C repressor binding site located in the TERT minimal promoter. The subject methods and compositions find use in a variety of different applications, including the immortalization of cells, the production of reagents for use in life science research, therapeutic applications; therapeutic agent screening applications; and the like. In further describing the subject invention, the methods and compositions of the invention are described first in greater detail, followed by a review of the various applications in which the subject invention finds use.

Dependent claims

An in vitro method of determining whether an agent inhibits Site C repression of Telomerase Reverse Transcriptase (TERT) transcription, said method comprising:

(a) contacting said agent with an expression system comprising a Site C repressor binding site and a coding sequence operably linked to a TERT promoter under conditions such that in the absence of said agent transcription of said coding sequence is repressed;
(b) determining whether transcription of said coding sequence is repressed in the presence of said agent;
and
(c) identifying said agent as an agent that inhibits Site C repression of TERT transcription if transcription of said coding sequence is not repressed in the presence of said agent.
