mTOR is a central nutrient sensor that signals a cell to grow and proliferate. Through distinct protein complexes it regulates different levels of available cellular energy substrates required for cell growth. One of the important functions of the complex is to maintain available amino acid pool by regulating protein translation. Dysregulation of mTOR(More)
Mammalian target of rapamycin (mTOR) controls cellular growth and proliferation by virtue of its ability to regulate protein translation. Eukaryotic initiation factor 4E (eIF4E) binding protein 1 (4E-BP1) - a key mTOR substrate, binds and sequesters eIF4E to impede translation initiation that is supposedly overcome upon 4E-BP1 phosphorylation by mTOR.(More)
Colorectal cancer (CRC) commonly known as bowel cancer is the third most common cause of cancer-related deaths in the western world and has been reported to show geographical variation in its incidence. Cancer development and progression is a complex process dictated by changes in expression and regulation of various genes which include tumor suppressor(More)
Bupivacaine is an amide type long acting local anesthetic used for epidural anesthesia and nerve blockade in patients. Use of bupivacaine is associated with severe cytotoxicity and apoptosis along with inhibition of cell growth and proliferation. Although inhibition of Erk, Akt, and AMPK seemingly appears to mediate some of the bupivacaine effects,(More)
S6K1 regulation associates a central role with dynamics of sequential phosphorylations at the hydrophobic motif (T412) and activation loop (T252) of the enzyme, such that the hydrophobic motif phosphorylation supposedly brought about by mTOR- kinase, primes the enzyme for PDK1 dependent phosphorylation at the activation loop for its full activation.(More)
Ribosomal protein S6 kinase 1(S6K1) is an evolutionary conserved kinase that is activated in response to growth factors and viral stimuli to influence cellular growth and proliferation. This downstream effector of target of rapamycin (TOR) signaling cascade is known to be directly activated by TOR- kinase mediated hydrophobic motif (HM) phosphorylation at(More)
