Abstract

Peroxisome proliferator-activated receptor alpha (PPAR-α) belongs to the PPAR family and plays a critical role in inhibiting cell proliferation and tumorigenesis in various tumors. However, the role of PPAR-α in colorectal tumorigenesis is unclear. In the present study, we found that fenofibrate, a PPAR-α agonist, significantly inhibited cell proliferation and induced apoptosis in colorectal carcinoma cells. In addition, PPAR-α was expressed in the nucleus of colorectal carcinoma cells, and the expression of nuclear PPAR-α increased in colorectal carcinoma tissue compared with that of normal epithelium tissue (P<0.01). The correlation between the expression of nuclear PPAR-α and clinicopathological factors was evaluated in human colorectal carcinoma tissues, and the nuclear expression of PPAR-α was significantly higher in well-to-moderately differentiated adenocarcinoma than in mucinous adenocarcinoma (P<0.05). These findings indicate that activation of PPAR-α may be involved in anticancer effects in colorectal carcinomas, and nuclear expression of PPAR-α may be a therapeutic target for colorectal adenocarcinoma treatment.

过氧化物酶体增殖因子激活受体α的激活和表达与大肠癌的发生有关

过氧化物酶体增殖物激活受体α（PPAR-α）属于PPAR家族，在抑制各种肿瘤的细胞增殖和肿瘤发生方面发挥着关键作用。然而，PPAR-α在结直肠肿瘤发生中的作用尚不清楚。在本研究中，我们发现PPAR-α激动剂非诺贝特显著抑制结直肠癌细胞的增殖并诱导细胞凋亡。此外，PPAR-α在结直肠癌细胞核中表达，与正常上皮组织相比，结直肠癌细胞核PPAR-α的表达增加（P<0.01），PPAR-α在中分化腺癌中的核表达显著高于粘液腺癌（P<0.05）。这些发现表明PPAR-α的激活可能与结直肠癌的抗癌作用有关，PPAR-α核表达可能是结直肠癌治疗的治疗靶点。

期刊介绍： PPAR Research is a peer-reviewed, Open Access journal that publishes original research and review articles on advances in basic research focusing on mechanisms involved in the activation of peroxisome proliferator-activated receptors (PPARs), as well as their role in the regulation of cellular differentiation, development, energy homeostasis and metabolic function. The journal also welcomes preclinical and clinical trials of drugs that can modulate PPAR activity, with a view to treating chronic diseases and disorders such as dyslipidemia, diabetes, adipocyte differentiation, inflammation, cancer, lung diseases, neurodegenerative disorders, and obesity.
