Colon cancer is a complex malignancy characterized by intricate molecular interactions that influence its progression. This study investigates the role of calcium channel gene expression (ORAI1 and Piezo1) and their interplay with angiogenesis-related genes (VEGFA, CCL3, and NF-KB1) in colon cancer tissue biopsies. Additionally, we explore the mutation profiles of pivotal oncogenes (KRAS, PI3KCA, and BRAF) and their potential correlations with calcium channel and angiogenesis-related gene expression. The results indicate significant upregulation of ORAI1 and Piezo1, suggesting their involvement in colon cancer pathogenesis. Correlations between ORAI1 and VEGFA/CCL3 highlight potential crosstalk between calcium signaling and angiogenesis. The mutation analysis identifies prevalent oncogenic mutations, while intriguing connections between gene expression and oncogenic mutations emerge. Notably, mutant KRAS exon 2 samples exhibit elevated CCL3 and VEGFA expression, suggesting a nuanced link between specific KRAS mutations and the tumor microenvironment. These findings illuminate the intricate molecular landscape of colon cancer and emphasize the potential roles of calcium channels, angiogenesis-related genes, and oncogenic mutations as prognostic markers and therapeutic targets.
结肠癌是一种复杂的恶性肿瘤,其特征是复杂的分子相互作用,影响其进展。本研究调查了钙通道基因表达(ORAI1 和 Piezo1)及其与血管生成相关基因(VEGFA、CCL3 和 NF-KB1)在结肠癌组织活检中的相互作用。此外,我们还探讨了关键癌基因(KRAS、PI3KCA 和 BRAF)的突变谱及其与钙通道和血管生成相关基因表达的潜在相关性。结果表明,ORAI1 和 Piezo1 的表达显著上调,提示它们参与了结肠癌的发病机制。ORAI1 与 VEGFA/CCL3 之间的相关性表明钙信号转导与血管生成之间存在潜在的串扰。突变分析确定了常见的致癌突变,同时基因表达与致癌突变之间出现了有趣的联系。值得注意的是,突变型 KRAS 外显子 2 样本中 CCL3 和 VEGFA 的表达升高,表明特定 KRAS 突变与肿瘤微环境之间存在细微的联系。这些发现阐明了结肠癌复杂的分子图谱,并强调了钙通道、血管生成相关基因和致癌突变作为预后标志物和治疗靶点的潜在作用。
