Colon cancer, thyroid cancer, and melanoma are common malignant tumors that seriously threaten human health globally. The B-Raf proto-oncogene, serine/threonine kinase (BRAF)(V600E) mutation is an important driver gene mutation in these cancer types. In this study, we identified that collagen triple helix repeat containing 1 (CTHRC1) expression was associated with the BRAF(V600E) mutation in colon cancer, thyroid cancer, and melanoma. Based on database analysis and clinical tissue studies, CTHRC1 was verified to correlate with poor prognosis and worse clinicopathological features in colon cancer and thyroid cancer patients, but not in patients with melanoma. Several signaling pathways, immune cell infiltration, and immunotherapy markers were associated with CTHRC1 expression. Additionally, a high level of CTHRC1 was correlated with decreased sensitivity to antitumor drugs (vemurafenib, PLX-4720, dabrafenib, and SB-590885) targeting the BRAF(V600E) mutation. This study provides evidence of a significant correlation between CTHRC1 and the BRAF(V600E) mutation, suggesting its potential utility as a diagnostic and prognostic biomarker in human colon cancer, thyroid cancer, and melanoma.
结肠癌、甲状腺癌和黑色素瘤是全球范围内严重威胁人类健康的常见恶性肿瘤。B-Raf原癌基因丝氨酸/苏氨酸激酶(BRAF)(V600E)突变是这些癌症类型中的一种重要驱动基因突变。在本研究中,我们发现含胶原三螺旋重复序列1(CTHRC1)的表达与结肠癌、甲状腺癌和黑色素瘤中的BRAF(V600E)突变相关。基于数据库分析和临床组织研究,CTHRC1被证实与结肠癌和甲状腺癌患者的预后不良及较差的临床病理特征相关,但在黑色素瘤患者中并非如此。几种信号通路、免疫细胞浸润和免疫治疗标志物与CTHRC1表达相关。此外,高水平的CTHRC1与针对BRAF(V600E)突变的抗肿瘤药物(维莫非尼、PLX-4720、达拉非尼和SB-590885)敏感性降低相关。本研究提供了CTHRC1与BRAF(V600E)突变之间显著相关性的证据,表明其在人类结肠癌、甲状腺癌和黑色素瘤中作为诊断和预后生物标志物的潜在用途。
