Polo-like kinase 1 (PLK1) plays a fundamental role in the spatiotemporal control of mitosis. Cells lacking PLK1 activity exhibit characteristic chromosome misalignment due to defects in microtubule-kinetochore organization and attachment. In our recently published paper, we uncover a new role for PLK1 in the preservation and maintenance of centromere integrity.

Polo-like kinase 1 (PLK1), a key regulator of the G2/M phase in mitosis, is frequently overexpressed in numerous tumors. Although PLK1 inhibitors have emerged as promising therapeutic agents for cancer, their use has been linked to significant anemia in a subset of patients, yet the underlying mechanisms remain poorly understood. In this study, we utilized an human umbilical cord blood-derived CD34 cell-based erythroid differentiation system, alongside a murine model, to investigate the impact of PLK1 inhibitors on erythropoiesis.

Nasopharyngeal carcinoma (NPC) presents significant treatment challenges due to its complex etiology and late-stage diagnosis. The traditional Chinese medicine Selaginella doederleinii Hieron (S. doederleinii) has shown potentiality in NPC treatment due to its multi-target, multi-pathway anti-cancer mechanisms.

Introduction: Flavonoids including quercetin, kaempferol, myricetin, rutin etc. have always been a part of traditional Chinese medicine for the treatment of several ailments. Rutin (RT), also known as rutoside, sophorin is one of the flavanol glycoside having structure resemblance with quercetin.

Background: Mitosis and cytokinesis are regulated by reversible phosphorylation events controlled by kinases and phosphatases. Drosophila Polo kinase, like its human ortholog PLK1, plays several roles in this process. Multiple mechanisms contribute to regulate Polo/PLK1 activity, localization and interactions.

Incomplete sister centromere decatenation results in centromeric ultrafine anaphase bridges (UFBs). PICH (PLK1-interacting checkpoint helicase), a DNA translocase, plays a crucial role in UFB resolution by recruiting UFB-binding proteins and stimulating topoisomerase IIα. However, the involvement of distinct PICH functions in UFB resolution remains ambiguous.
