Summary: This study identified Cdk5 as a suppressor of osteoblast differentiation through unbiased kinome RNAi screening. Cdk5 knockdown or inhibition enhanced osteoblastogenesis in vitro, and it was found to regulate osteoblast differentiation through the MAPK pathway. These findings suggest that Cdk5 may be a potential therapeutic target for treating osteoporosis and improving fracture healing.

Summary: The study identified that the overactivation of Cdk5 is associated with the development of tauopathies. Roscovitine, a Cdk5 inhibitor, reduces the phosphorylation level of tau protein and mitigates the pathologic phosphorylation of tau by inhibiting the calpain signaling pathway, thereby alleviating the degeneration of RGCs.

Summary: In this study, the altered expression and misregulation of miR-650 in Alzheimer's disease (AD) brains were observed. Bioinformatic analysis predicted that miR-650 targets three AD-associated genes, and experimental confirmation showed that miR-650 significantly reduces their expression levels in vitro. Overexpression of miR-650 was shown to alter CDK5 levels and ameliorate AD pathologies in transgenic mice. These findings suggest that miR-650 influences AD pathogenesis through regulation of CDK5.

Summary: This study identified SIRT5 as a novel substrate of Cyclin F, which regulates cell cycle and metabolism through interaction with Cyclin F. The knockout of SIRT5 results in changes in cell cycle signaling congruent with S and G2/M phase increase. These findings suggest a connection between SIRT5, cell cycle regulation, and metabolism.

Summary: This study indicates that inhibition of CDK5 can provide neuroprotection by regulating the phosphorylation of Drp1S616, mitigating mitochondrial fragmentation and apoptosis induced by cerebral ischemia. The findings help in the development of drug targeting the CDK5 signaling pathway for clinical use in treating cerebral ischemia.

Summary: This study identifies a novel mechanism in which OGT regulates acetate-dependent acetyl-CoA and lipid production by regulating phosphorylation of ACSS2 by CDK5. The OGT/CDK5/ACSS2 pathway may be a potential target for treating altered metabolic dependencies in brain tumors.

Summary: Cdk1 is a master regulator of the cell cycle, controlling progression through different phases. It also directly regulates RNA polymerase activity, which is important for protein synthesis and meeting cellular demands. This regulation promotes cell cycle entry.

Summary: Mast cells (MCs) are heterogeneous immune cells with different protease repertoires and receptor expressions. A new cell line, PMC-306, derived from primary peritoneal MCs, can be used to study PMC function and tumorigenic processes associated with MC leukemia.

Summary: Tamoxifen modulates the phosphorylation status of TAU protein in Alzheimer's disease and inhibits CDK5 kinase activity. Two novel inhibitors of CDK5/p25 complex are identified, which can reduce the risk of recurrence of ER+ breast cancers and prevent drawbacks induced by tamoxifen exposure.

Summary: Pancreatic neuroendocrine tumors (PanNETs) are a type of tumor that arises from hormone-secreting islet cells of the pancreas. A new inducible, conditional mouse model of PanNETs has been developed, which will facilitate molecular delineation of Cdk5-dependent PanNETs and the development of new targeted therapeutics.

Summary: This study investigated the functional roles of Giardia lamblia CDKs (GlCDKs) and their cognate cyclins. Using morpholino-mediated knockdown and coimmunoprecipitation, the functions of GlCDK1 and GlCDK2 were distinguished. GlCDK1 with Glcyclin 3977 plays a crucial role in flagellum formation and cell cycle control of G. lamblia, while GlCDK2 with Glcyclin 22394/6584 is involved in cell cycle control.

Summary: Abemaciclib, a CDK inhibitor for breast cancer treatment, also targets HIPKs and DYRK1A. HIPKs play a role in signal pathway regulation, and DYRK1A is inhibited by Abemaciclib in vitro to a similar extent as Cdk4/Cdk6.
