Evidence of selection for clones having genetic inactivation of the activin A type II receptor (ACVR2) gene in gastrointestinal cancers.
The activin signaling pathway parallels the transforming growth factor (TGF)-beta pathway. Both use extracellular ligands and cell surface receptors that are structurally and functionally related, as well as the same intracellular mediators (SMADs 2-4) to transmit these signals. Members of both pathways have been characterized previously as tumor suppressor genes on the demonstration of inactiv...
متن کاملActivin Type II Receptor Restoration in ACVR2-Deficient Colon Cancer Cells Induces Transforming Growth Factor- Response Pathway Genes
The activin type II receptor (ACVR2) gene is a putative tumor suppressor gene that is frequently mutated in microsatellite-unstable colon cancers (MSI-H colon cancers). ACVR2 is a member of the transforming growth factor (TGF)type II receptor (TGFBR2) family and controls cell growth and differentiation. SMAD proteins are major intracellular effectors shared by ACVR2 and TGFBR2 signaling; howeve...

متن کاملActivin-A up-regulates type I activin receptor mRNA levels in human immortalized extravillous trophoblast cells.
Activin is known to play an important regulatory role in reproduction, including pregnancy. To further examine the role and signaling mechanism of activin in regulating placental function, the steady-state level of activin type I receptor (ActRI) mRNA in immortalized extravillous trophoblasts (IEVT) cells was measured using competitive PCR (cPCR). An internal standard of ActRI cDNA for cPCR was...
متن کاملTruncated activin type I receptor Alk4 isoforms are dominant negative receptors inhibiting activin signaling.
Activin, a member of the transforming growth factor beta (TGFbeta) superfamily of cytokines, inhibits cell proliferation in a variety of cell types. The functions of activin are mediated by type I and type II serine/threonine kinase receptors. The main type I receptor mediating activin signaling in human cells is ActRIB, also called Alk4. We have previously reported that several truncated Alk4 ...
