Upregulation of DR5 receptor by the diaminothiazole DAT1 [4-amino-5-benzoyl-2-(4-methoxy phenyl amino) thiazole] triggers an independent extrinsic pathway of apoptosis in colon cancer cells with compromised pro and antiapoptotic proteins
Mitochondria mediated signalling is the more common way of apoptosis induction exhibited by many chemotherapeutic agents in cancer cells. Death receptor mediated signalling for apoptosis in many cells also requires further amplification from the mitochondrial pathway activation through tBid. . more
Smurf E3 ubiquitin ligases at the cross roads of oncogenesis and tumor suppression
Smad ubiquitin regulatory factors (Smurfs) belong to the HECT- family of E3 ubiquitin ligases and comprise mainly of two members, Smurf1 and Smurf2. Initially, Smurfs have been implicated in determining the competence of cells to respond to TGF-ß/BMP signaling pathway.more

Plumbagin  inhibits tumorigenesis and angiogenesis of ovarian cancer cells <em>in  vivo</em>
Plumbagin inhibits tumorigenesis and angiogenesis of ovarian cancer cells in vivo
Plumbagin inhibits OVCAR-5 tumor growth in SCID mice. Mice received subcutaneous injections of OVCAR-5 cells, and tumors were allowed to grow for 28 days before the initiation of single-agent treatment with plumbagin (1mg/kg) in 25% PEG. The control group received only 25% PEG. A. Images depicting differences in OVCAR-5 tumor growth with and without plumbagin treatment. B. Average OVCAR-5 tumor volume after 3 weeks of treatment in control and treatment groups. ×××, p = 0.0001, paired t test, 2 tailed). C. Significant regression in tumor weight has been observed. ××, p = 0.001 (treated group vs. control group, paired t test, 2 tailed). Plumbagin inhibits tumor cell proliferation in vivo. Ki67-stained tumor sections: D. Control group received only 25% PEG, E. received plumbagin in 25% PEG. Plumbagin alone demonstrated a significant effect on the inhibition of the Ki67 level. F. Quantitation of the Ki67 positive cells. ×××, p = 0.0001 (treated group vs. control group, paired t test, 2 tailed). Plumbagin inhibits angiogenesis in vivo. vWF stained sections: G. Control group received only 25% PEG, H. received plumbagin in 25% PEG, showing no staining of vWF... more
Cyclophilin A rushes out when glucose treads in!
Cyclophilin A rushes out when glucose treads in!
Glucose, the primary source of energy to living organisms and the simplest sugar in human metabolism, creates havoc to cells when its levels are elevated.  In humans hyperglycemia can activate monocytes, the precursors to chronic inflammation resulting in secretion of proteins in their kitty.... more
Transcriptional Repression of Ring Finger Protein 144A by Metastasis-Associated Protein1 Confers a Migratory and Invasive Phenotype
MTA1, a component of NuRD complex, transcriptionally represses the expression of RNF144A, by recruiting HDAC2 and c/EBPα co-repressor complex onto its promoter; and that depletion of endogenous RNF144A renders cancer cells a more migratory and invasive phenotype...... more
