分子生物学分子生物学
癌症研究癌症研究

背景情况:

循环素D1 (CDDN1) 调节细胞循环通过G1阶段的进展,并由循环素依赖的激酶CDK4和CDK6.6控制.
了解CDDN1的作用对于推进前列腺癌 (PCa) 研究和治疗策略至关重要.

研究的目的:

研究前列腺癌 (PCa) 中CDDN1表达水平和临床病理特征之间的关联.
确定CDDN1是否可以作为PCa患者结果的预后生物标志物.

主要方法:

对90个前列腺组织样本的回顾性分析 (75个PCa,15个良性前列腺缩).
免疫组织化学染色以将CDDN1表达分类为"低" (L) 或"高" (H).
临床病理特征和存活率的统计评估,使用95%的置信区间.

主要成果:

与高CDDN1表达 (p=0.011) 的患者相比,CDDN1表达低的患者的整体存活时间 (OS) 显著更长 (p=0.011).
高CDDN1表达与66个月的中位数OS相关,而低CDDN1组的OS尚未达到.
考克斯回归确定了CDDN1水平,乳酸脱酶和治疗后的PSA作为PCa中OS的显著预后因素.

Positive Regulator Molecules

Positive Regulator Molecules

Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

M-Cdk Drives Transition Into Mitosis

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
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.
M cyclin...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
