The G 2 phase cells, which have double (4C) the normal micronuclear DNA content, undergo pre-meiotic DNA synthesis when conjugated with G 1 phase cells. The micronucleus of the progeny from the cross between a G 1 and a G 2 cell becomes triploid....

细胞周期发生在大约24小时(在一个典型的人类细胞中)和两个不同的阶段:间期,包括细胞周期的三个阶段(g1、s和g2)和有丝分裂(m)。在占真核细胞周期95%的间期,细胞在有丝分裂前生长并复制其DNA。 相间阶段 在有丝分裂和胞质分裂的每个阶段之后,真核细胞进入间期,在此期间它们生长并复制其DNA,为下一次有丝分裂...

These findings indicate that silymarin and silibinin modulate G1 phase cyclins-CDKs-CDKIs for G1 arrest, and the Chk2-Cdc25C-Cdc2/cyclin B1 pathway for G2-M arrest, together with an altered subcellular localization of critical cell cycle regulators. Overall, we observed comparable effects for...
目前针对分化良好的G1级或G2级胰腺外的神经内分泌肿瘤的全身治疗包括生长抑素类似物(SSAs)[1]、化疗、依维莫司[2]、肽受体放射性核素治疗(生长抑素受体阳性的胃肠胰神经内分泌肿瘤)[3]等。舒尼替尼作为靶向VEGFR1/2/3、PDGFR的...
IF HeLa cells that are synthesising DNA (S phase) are fused with others in the G1 phase of the cell cycle, DNA synthesis is prematurely induced in the G1 nuclei. But if S-phase cells are fused with G2 phase cells, which have already-replicated their DNA, synthesis is not induced in...
Western blotting analysis showed that WPBFE could cause the arrest of cell cycle in G0/G1 phase by down-regulating expression levels of PCNA, CDK4, cyclin D1 and up-regulating the expression level of p21. Meanwhile...
The FLM method allowed the conclusion that G1-phase variability resulted from constancy of S and G2 phase lengths. In contrast, with FACS analysis, slow growing cells exhibiting a large fraction of cells with a G1-phase amount of DNA appeared to be arrested in G1 phase. The loss of ...
