Drosophila TRIM32 cooperates with glycolytic enzymes to promote cell growth

Madm (Mlf1 adapter molecule) cooperates with Bunched A to promote growth in Drosophila

BACKGROUND The TSC-22 domain family (TSC22DF) consists of putative transcription factors harboring a DNA-binding TSC-box and an adjacent leucine zipper at their carboxyl termini. Both short and long TSC22DF isoforms are conserved from flies to humans. Whereas the short isoforms include the tumor suppressor TSC-22 (Transforming growth factor-beta1 stimulated clone-22), the long isoforms are larg...

FcμR interacts and cooperates with the B cell receptor To promote B cell survival.

The IgM FcR (FcμR) promotes B cell survival, but the molecular mechanism remains largely unknown. We show using FcμR(-/-) and wild-type mice that FcμR specifically enhanced B cell survival induced by BCR cross-linking with F(ab')2-anti-IgM Abs while having no effect on survival when the B cells were activated by CD40 ligation or LPS stimulation. FcμR expression was markedly upregulated by anti-...

FcmR Interacts and Cooperates with the B Cell Receptor To Promote B Cell Survival

XRCC5 cooperates with p300 to promote cyclooxygenase-2 expression and tumor growth in colon cancers

Cyclooxygenase (COX) is the rate-limiting enzyme in prostaglandins (PGs) biosynthesis. Previous studies indicate that COX-2, one of the isoforms of COX, is highly expressed in colon cancers and plays a key role in colon cancer carcinogenesis. Thus, searching for novel transcription factors regulating COX-2 expression will facilitate drug development for colon cancer. In this study, we identifie...

Ku80 cooperates with CBP to promote COX-2 expression and tumor growth

Cyclooxygenase-2 (COX-2) plays an important role in lung cancer development and progression. Using streptavidin-agarose pulldown and proteomics assay, we identified and validated Ku80, a dimer of Ku participating in the repair of broken DNA double strands, as a new binding protein of the COX-2 gene promoter. Overexpression of Ku80 up-regulated COX-2 promoter activation and COX-2 expression in l...
