Colorectal cancer (CRC) is a malignancy of the large intestine, whose development and prognosis have been demonstrated to be associated with altered lipid metabolism. High cholesterol intake is associated with an increased risk of CRC, and elevated serum cholesterol levels are known to be correlated with risk of developing CRC. Niemann-Pick C1-Like 1 (NPC1L1), a target of ezetimibe, plays an essential role in the absorption of intestinal cholesterol. However, whether the altered expression of NPC1L1 affects CRC development and prognosis is currently unknown. Data corresponding to patients with CRC were obtained from The Cancer Genome Atlas (TCAG). Datasets from the Genome Data Analysis Center (GDAC) platform were analyzed to compare the expression of NPC1L1 in normal and CRC tissues using the Mann–Whitney U test and chi-square test. Further, the datasets from the Gene Expression Omnibus (GEO) database were analyzed. The log-rank test and multivariate Cox proportional hazard regression analysis were performed to determine whether NPC1L1 significantly affects the prognosis of CRC. The expression of NPC1L1 was found to be upregulated in CRC and was significantly associated with the N and pathological stages but not with the histological type, age, and sex. Increased NPC1L1 expression in CRC was related to poor patient survival, as evidenced by the Kaplan–Meier and multivariate regression analyses. As high expression of NPC1L1 was associated with CRC development, pathological stage, and prognosis, NPC1L1 can serve as an independent prognostic marker for CRC.

Niemann-Pick C1-Like 1 在结直肠癌中的表达和预后意义:一项回顾性队列研究

结直肠癌 (CRC) 是大肠的恶性肿瘤,其发展和预后已被证明与脂质代谢改变有关。高胆固醇摄入与 CRC 风险增加有关,已知血清胆固醇水平升高与发生 CRC 风险相关。Niemann-Pick C1-Like 1 (NPC1L1) 是依折麦布的靶点,在肠道胆固醇的吸收中起重要作用。然而,NPC1L1 的表达改变是否影响结直肠癌的发展和预后目前尚不清楚。对应于 CRC 患者的数据来自癌症基因组图谱 (TCAG)。使用 Mann-Whitney U 检验和卡方检验分析来自基因组数据分析中心 (GDAC) 平台的数据集以比较 NPC1L1 在正常和 CRC 组织中的表达。更远,分析了来自 Gene Expression Omnibus (GEO) 数据库的数据集。进行对数秩检验和多变量Cox比例风险回归分析以确定NPC1L1是否显着影响CRC的预后。发现 NPC1L1 的表达在 CRC 中上调,并且与 N 和病理阶段显着相关,但与组织学类型、年龄和性别无关。Kaplan-Meier 和多变量回归分析证明,CRC 中 NPC1L1 表达增加与患者存活率差有关。由于 NPC1L1 的高表达与 CRC 的发展、病理分期和预后相关,NPC1L1 可以作为 CRC 的独立预后标志物。进行对数秩检验和多变量Cox比例风险回归分析以确定NPC1L1是否显着影响CRC的预后。发现 NPC1L1 的表达在 CRC 中上调,并且与 N 和病理阶段显着相关,但与组织学类型、年龄和性别无关。Kaplan-Meier 和多变量回归分析证明,CRC 中 NPC1L1 表达增加与患者存活率差有关。由于 NPC1L1 的高表达与 CRC 的发展、病理分期和预后相关,NPC1L1 可以作为 CRC 的独立预后标志物。进行对数秩检验和多变量Cox比例风险回归分析以确定NPC1L1是否显着影响CRC的预后。发现 NPC1L1 的表达在 CRC 中上调,并且与 N 和病理阶段显着相关,但与组织学类型、年龄和性别无关。Kaplan-Meier 和多变量回归分析证明,CRC 中 NPC1L1 表达增加与患者存活率差有关。由于 NPC1L1 的高表达与 CRC 的发展、病理分期和预后相关,NPC1L1 可以作为 CRC 的独立预后标志物。发现 NPC1L1 的表达在 CRC 中上调,并且与 N 和病理阶段显着相关,但与组织学类型、年龄和性别无关。Kaplan-Meier 和多变量回归分析证明,CRC 中 NPC1L1 表达增加与患者存活率差有关。由于 NPC1L1 的高表达与 CRC 的发展、病理分期和预后相关,NPC1L1 可以作为 CRC 的独立预后标志物。发现 NPC1L1 的表达在 CRC 中上调,并且与 N 和病理阶段显着相关,但与组织学类型、年龄和性别无关。Kaplan-Meier 和多变量回归分析证明,CRC 中 NPC1L1 表达增加与患者存活率差有关。由于 NPC1L1 的高表达与 CRC 的发展、病理分期和预后相关,NPC1L1 可以作为 CRC 的独立预后标志物。
