Cyclin B-Cdk1 Controls Pronuclear Union in Interphase [PDF]
In sexual reproduction, the union of the male and female pronuclei occurs in fertilized eggs to mix genetic materials derived from both parents, thereby creating a new genome for the next generation [1-4]. The process leading to pronuclear union consists of pronuclear congression, which depends on astral microtubules derived from sperm centrosome [5-8],

Carrying-over effects of GVBD blocking on post-blocking meiotic progression of oocytes: species difference and the signaling pathway leading to MPF activation. [PDF]
Efforts to improve the quality of in vitro matured oocytes by blocking germinal vesicle breakdown (GVBD) and allowing more time for ooplasmic maturation have achieved little due to a lack of knowledge on the molecular events during GVBD blocking.

Cyclin D3 expression in non-Hodgkin lymphoma. Correlation with other cell cycle regulators and clinical features [PDF]
Udgivelsesdato: 2001-MarCyclin D3 is the most widely expressed D-type cyclin and can be rate limiting for G1/S transition. To study the expression of cyclin D3 in non-Hodgkin lymphoma, samples from 198 previously untreated patients with lymphoma from a ...

Characterization and localization of cyclin B3 transcript in both oocyte and spermatocyte of the rainbow trout (Oncorhynchus mykiss) [PDF]
B-type cyclins are regulatory subunits with distinct roles in the cell cycle. To date, at least three subtypes of B-type cyclins (B1, B2, and B3) have been identified in vertebrates. Previously, we reported the characterization and expression profiles of

eIF4A inhibitors suppress cell-cycle feedback response and acquired resistance to CDK4/6 inhibition in cancer [PDF]
CDK4/6 inhibitors are FDA-approved drugs for estrogen receptor-positive (ER+) breast cancer and are being evaluated to treat other tumor types, including KRAS-mutant non-small cell lung cancer (NSCLC).

Cycling through mammalian meiosis: B-type cyclins in oocytes [PDF]
B-type cyclins in association with Cdk1 mediate key steps of mitosis and meiosis, by phosphorylating a plethora of substrates. Progression through the meiotic cell cycle requires the execution of two cell divisions named meiosis I and II without intervening S-phase, to obtain haploid gametes.

Botryococcus braunii produce liquid hydrocarbons able to be processed into combustion engine fuels. Depending on the growing conditions, the cell doubling time can be up to 6 days or more, which is a slow growth rate in comparison with other microalgae ...

Cyclin D1 promotes BRCA2-Rad51 interaction by restricting cyclin A/B-dependent BRCA2 phosphorylation [PDF]
BRCA2 has an important role in the maintenance of genome stability by interacting with RAD51 recombinase through its C-terminal domain. This interaction is abrogated by cyclin A-CDK2-mediated phosphorylation of BRCA2 at serine 3291 (Ser3291). Recently, we showed that cyclin D1 facilitates RAD51 recruitment to BRCA2-containing DNA repair foci, and that ...

Distinct and Overlapping Requirements for Cyclins A, B, and B3 in Drosophila Female Meiosis
Meiosis, like mitosis, depends on the activity of the cyclin dependent kinase Cdk1 and its cyclin partners. Here, we examine the specific requirements for the three mitotic cyclins, A, B, and B3 in meiosis of Drosophila melanogaster.

Mip/LIN-9 Regulates the Expression of B-Myb and the Induction of Cyclin A, Cyclin B, and CDK1 [PDF]
Members of the novel family of proteins that include Drosophila Mip130, Caenorhabditis elegans LIN-9, and mammalian LIN-9 intervene in different cellular functions such as regulation of transcription, differentiation, transformation, and cell cycle progression. Here we demonstrate that LIN-9, designated as Mip/LIN-9, interacts with B-Myb but not with c-
