Mutations in oncogenes and tumor suppressor genes can significantly impact cellular function during cancer development. A comprehensive analysis of their mutation patterns and significant gene ontology terms can provide insights into cancer emergence and suggest potential targets for drug development. This study analyzes twelve cancer subtypes by focusing on significant genetic and molecular factors. Two common genetic mutations associated with cancer are single nucleotide variants (SNVs) and copy number alterations (CNAs). Oncogenes, derived from mutated proto-oncogenes, disrupt normal cell functions and promote cancer, while tumor suppressor genes, often inactivated by mutations, regulate cell processes like proliferation and DNA damage response. This study analyzed datasets from The Cancer Genome Atlas (TCGA), which provides extensive genomic data across various cancers. In our analysis results, many genes with significant -values based on Kaplan Meier gene expression data were identified in eight cancers (BRCA, BLCA, HNSC, KIRC, LUAD, KIRP, LUSC, STAD). Moreover, STAD is the only cancer for genes with both significant -values and functional terms reported. Interestingly, we found that LIHC was the cancer reported with only one CNA mutated gene and its survival plot -value being significant. Additionally, KICH has no reported significant genes at all. Our study proposed the relationship between tumor suppressor and oncogenes and shed light on cancer tumorigenesis due to genetic mutations.
癌基因和肿瘤抑制基因的突变在癌症发展过程中会显著影响细胞功能。对其突变模式和重要的基因本体学术语进行全面分析,可为癌症的发生提供见解,并为药物开发指明潜在靶点。本研究通过聚焦重要的遗传和分子因素,对十二种癌症亚型进行了分析。与癌症相关的两种常见基因突变是单核苷酸变异(SNV)和拷贝数改变(CNA)。由突变的原癌基因衍生而来的癌基因会破坏正常细胞功能并促进癌症发生,而肿瘤抑制基因通常因突变而失活,可调节细胞增殖和DNA损伤反应等细胞过程。本研究分析了来自癌症基因组图谱(TCGA)的数据集,该数据集提供了各种癌症的广泛基因组数据。在我们的分析结果中,在八种癌症(乳腺癌、膀胱癌、头颈部鳞状细胞癌、肾透明细胞癌、肺腺癌、肾乳头状细胞癌、肺鳞状细胞癌、胃癌)中鉴定出了许多基于Kaplan Meier基因表达数据具有显著P值的基因。此外,胃癌是唯一报告了具有显著P值和功能术语的基因的癌症。有趣的是,我们发现肝癌是报告中仅有一种CNA突变基因且其生存曲线P值显著的癌症。此外,肾嫌色细胞癌根本没有报告显著基因。我们的研究提出了肿瘤抑制基因和癌基因之间的关系,并揭示了基因突变导致癌症发生的机制。
