WebbAmong them, PLK1 is studied mostly, 8 and plays important functions in regulating cell cycle. 9 According to previous studies, we concluded that high expression of PLK1 contributed to a poor prognosis in some human cancers. 10–12 Functionally, PLK1 promotes tumor progression through different pathways, for example, inhibition of PLK1 … WebbBackground and Purpose: Over the last decade, the inhibition of PLK1 has proven potent antiproliferative activity in vitro. However, the effectiveness of most synthetic targeted drugs has not yet been translated into clinics. Herein, we investigated the in vitro effects of two second-generation PLK1 inhibitors BI 6727 and GSK461364 in breast cancer cell …
WebbTo date, MTORC1's and PLK1's functions are mostly studied separately, and reports on their mutual crosstalk are scarce. Here, we identify PLK1 as a physical MTORC1 interactor in human cancer cells. Webb2 maj 2024 · In vitro, BLM phosphorylation by CDK/PLK1/TOPBP1 stimulates the dissolution of topologically linked DNA intermediates by BLM-TOP3A. Thus, we propose that the CDK1-TOPBP1-PLK1 axis enhances BTR-mediated dissolution of recombination intermediates late in the cell cycle to suppress crossover recombination and curtail …
WebbIn this respect, our studies identified HBc as a PLK1 substrate in vitro, and mapped PLK1 phosphorylation sites on this protein. PLK1 is a proviral host factor that could be envisaged as a target for combined antiviral and anti-tumoral strategies against HBV infection and HBV mediated carcinogenesis.

Webb1 feb. 2024 · PLK1 plays multiple roles in the cell cycle: controls mitotic entry and the G2/M checkpoint, coordinates the centrosome and cell cycles, regulates spindle assembly and … black panther ticket salesWebb13 mars 2007 · Our studies identify distinct functions of Plk1 throughout mitosis and cytokinesis and demonstrate the power of chemical genetics in dissecting these complex but short-lived events within human cells. Results To develop a chemical genetic system for Plk1, we first needed to eliminate the endogenous kinase from human cells. black panther ticket pricePlk1 is an early trigger for G2/M transition. Plk1 supports the functional maturation of the centrosome in late G2/early prophase and establishment of the bipolar spindle. Plk1 phosphorylates and activates cdc25C, a phosphatase that dephosphorylates and activates the cyclinB/cdc2 complex. Plk phosphorylates and … Visa mer Serine/threonine-protein kinase PLK1, also known as polo-like kinase 1 (PLK-1) or serine/threonine-protein kinase 13 (STPK13), is an enzyme that in humans is encoded by the PLK1 (polo-like kinase 1) gene Visa mer PLK1 consists of 603 amino acids and is 66kDa. In addition to the N-terminus kinase domain, there are two conserved polo-box regions of 30 amino … Visa mer Plk1 is considered a proto-oncogene, whose overexpression is often observed in tumor cells. Aneuploidy and tumorigenesis can also result from Visa mer PLK1 has been shown to interact with: • CHEK2, • NUDC, • PIN1, • PSMA3, Visa mer During interphase, PLK1 localizes to centrosomes. In early mitosis, it associates with mitotic spindle poles. A recombinant GFP … Visa mer PLK1 is being studied as a target for cancer drugs. Many colon and lung cancers are caused by K-RAS mutations. These cancers are dependent on PLK1. When PLK1 expression was silenced with RNA interference in cell culture, K-RAS cells were selectively … Visa mer • Polo-like kinases, the gene family that PLK1 belongs to Visa mer black panther throne roomWebb11 apr. 2024 · The C-terminal domain of UBAP2L mediates its function on PLK1 independently of its role in stress response signaling.
