Tumour suppressor function of RNase L in a mouse model

‏‎interpersonal function of language in subtitling

‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

A bipartite model of 2-5A-dependent RNase L.

The 2-5A-dependent RNase (RNase L) is a tightly regulated endoribonuclease of higher vertebrates that is catalytically active only after engaging unusual effector molecules consisting of the 2',5'-linked oligoadenylates, p1-3A(2'p5'A)>/=2 (2-5A). Progressive truncations from either terminus have provided insight into the structure, function, and regulation of RNase L. We determined that deletio...

Regulation and function of the INK4alARF tumour suppressor locus

Tumour suppressor function of protein tyrosine phosphatase receptor-T.

It has long been thought that PTPs (protein tyrosine phosphatases) normally function as tumour suppressors. Recent high-throughput mutational analysis identified loss-of-function mutations in six PTPs in human colon cancers, providing critical cancer genetics evidence that PTPs can act as tumour suppressor genes. PTPRT (protein tyrosine phosphatase receptor-T), a member of the family of type II...

The tumour suppressor PTEN: involvement of a tumour suppressor candidate protein in PTEN turnover.

The tumour suppressor PTEN (phosphatase and tensin homologue deleted on chromosome 10) plays essential roles in regulating signalling pathways involved in cell growth and apoptosis, and is inactivated in a wide variety of tumours. The role of PTEN as a tumour suppressor has been firmly established; however, the mechanism(s) by which its function and activity are regulated remains elusive. Here,...
