WebRibosomal S6 kinase (S6K) is a member of the AGC family of serine/threonine protein kinases and plays a key role in diverse cellular processes, including cell growth, survival and metabolism. Activation of S6K by growth factors, amino acids, energy levels and hypoxia is mediated by the mTOR and PI3K signalling pathways. WebIntroduction: mTOR and its downstream effectors the 4E-binding protein 1 (4EBP1) and the p70 ribosomal S6 kinases (S6K1 and S6K2) are frequently upregulated in breast cancer, and assumed to be driving forces in tumourigenesis, in close connection with oestrogen receptor (ER) networks. Here, we investigated these factors as clinical markers in five …
Web16 apr. 2024 · Immunoblots for PI3K/AKT/mTOR/S6K signaling-associated proteins in (A) MCF-7 and (B) MDA-MB-231 cells. Western blot analysis from the breast cells transfected with control siRNA (NC) or CSNK1G2 siRNA (CSNK1G2) were performed after treatment with vehicle or 10 nM E 2 for 24 h. Protein expression levels based on individual bands … WebThe mTORC1-S6K pathway inhibits DDR. We observed that cells were deficient in repairing DSBs induced by etoposide or ion radiation (IR) in the presence of AA, as evidenced by the sustained levels of γH2A.X and extended lengths of tail moments (Fig. 1a and Supplementary Fig. 1a, b).Given that AA has been shown to activate mTORC1 and its …
WebThe PI3K/AKT/mTOR signaling pathway (Figure 281.2) is critical for the regulation of cellular growth, proliferation, and survival. The serine/threonine protein kinase mTOR (also known as FKBP12-rapamycin associated protein (FRAP), or rapamycin and FKBP12 target (RAFT)) is a major effector of PI3K signaling. Web11 feb. 2024 · analogs that inhibit mTOR are currently being evaluated for their potential as anti-cancer agents, albeit with limited e cacy. mTORC1 mediates its function via its downstream targets 40S ribosomal S6 kinases (S6K) and eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1). There are two homologs of S6K: S6K1 and …
WebOriginally identified as a target of the mTORC1/S6K signaling pathway, we have shown SRPK2 to be a target of the Ras-ERK-Rsk pathway, as well as the PI3K-AKT. We discovered the S6K, AKT and RSK all phosphorylate SRPK2 at serine 494 in a cell-type, stimulus dependent manner, emphasizing the redundant nature of the AGC kinases.
Web23 dec. 2015 · Background: The AKT/mTORC1/S6K pathway is frequently overstimulated in breast cancer, constituting a promising therapeutic target. The benefit from mTOR inhibitors varies, likely as a consequence of tumour heterogeneity, and upregulation of several compensatory feed-back mechanisms.
