Abstract:
The protein kinase C (PKC) family comprises enzyme kinases that regulate cell survival, metabolism, and proliferation. PKC isotypes (PKCs) phosphorylate specific downstream substrates, thereby controlling critical steps in both mitotic and meiotic cell division. Throughout the cell cycle, PKCs orchestrate essential processes, such as chromosome segregation, recombination, and cell cycle progression. In vertebrates, PKCs play essential roles in oogenesis and the early stages of embryo development. Disruption of PKC signaling in mammalian oocytes can lead to errors in chromosome segregation and induce meiotic arrest. Therefore, investigating PKC function in meiosis is crucial for advancing fundamental biological research and for developing new approaches to infertility treatment.

Meiosis II
The timing and cell division patterns of meiosis differ between males and females. In male meiosis, the centrosomes are part of the formation of the meiotic spindle. However, in oocytes, including that of humans, Drosophila,...

Meiosis vs. Mitosis
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
