Circadian rhythms (CRs) are a key biological system regulating physiological processes such as metabolism, cell growth, DNA repair, and immunity, adapting to environmental changes like the light/dark cycle. Governed by internal clocks, it modulates gene expression through feedback loops involving Clock Genes (CGs), with the cycle initiated by CLOCK-BMAL1 and NPAS2-BMAL1 heterodimers. Disruptions in circadian rhythms have been linked to diseases including metabolic disorders, neurodegeneration, and cancer. CIPC (CLOCK-interacting pacemaker) has been studied as a negative regulator of the CLOCK-BMAL1 complex, focusing on its role in cancer, particularly leukemias. Public datasets and bioinformatics tools were used to examine gene expression in healthy patients and acute myeloid leukemia (AML) samples. Our analysis revealed significant overexpression of in AML compared to healthy tissues ( < 0.0001 ****). Additionally, survival analysis indicated significant differences in overall survival based on expression, with a log-rank test -value = 0.014, suggesting that expression may affect overall patient survival. Altered expression may contribute to leukemogenesis by inhibiting circadian genes, which are often disrupted in leukemia. Furthermore, interacts with oncogenic pathways, including the MAPK/ERK pathway, which is essential for cell proliferation. Additional studies are needed to validate these findings and explore the detailed role of in cancer development.
昼夜节律(CRs)是一个关键的生物系统,它调节着诸如新陈代谢、细胞生长、DNA修复和免疫等生理过程,以适应诸如光/暗周期等环境变化。由内部时钟控制,它通过涉及时钟基因(CGs)的反馈回路调节基因表达,该循环由CLOCK - BMAL1和NPAS2 - BMAL1异二聚体启动。昼夜节律的紊乱与包括代谢紊乱、神经退行性变和癌症在内的疾病有关。CIPC(与CLOCK相互作用的起搏器)已被作为CLOCK - BMAL1复合物的负调节因子进行研究,重点关注其在癌症,特别是白血病中的作用。使用公共数据集和生物信息学工具来检查健康患者和急性髓系白血病(AML)样本中的基因表达。我们的分析显示,与健康组织相比,AML中 显著过表达(< 0.0001 ****)。此外,生存分析表明基于 表达的总生存存在显著差异,对数秩检验 -值 = 0.014,这表明 表达可能影响患者的总生存。 表达的改变可能通过抑制昼夜节律基因而导致白血病发生,这些基因在白血病中常常被破坏。此外, 与致癌途径相互作用,包括对细胞增殖至关重要的MAPK/ERK途径。需要进一步的研究来验证这些发现并探索 在癌症发展中的详细作用。
