Transcription factors are involved in cell cycle and apoptosis regulation and thus have a key role in the carcinogenesis of different tumors. Nuclear factor of activated T-cells, cytoplasmic 2 (NFATc2) and peroxisome proliferator-activated receptor gamma (PPARG) transcription factors are important in the carcinogenesis of colorectal cancer (CRC). In this study, we examined whether the expression of NFATc2 and PPARG genes is significantly altered during the carcinogenesis of CRC. A total of 47 tumor samples and matched normal tissue margins were collected during surgery from patients with CRC. In addition, three CRC cell lines (HCT119, SW480, and HT29) and healthy cell line were used. After total RNA extraction and cDNA synthesis, mRNA expression levels of NFATc2 and PPARG were examined by real-time polymerase chain reaction. The results showed that NFATc2 is overexpressed in the tumor tissues compared with normal tissue margins (p ≤ 0.05). However, the mRNA expression levels of PPARG were not significantly different between the tumor tissues and tissue margins. Our results indicate that NFATc2 may be used as an early diagnostic or predictive biomarker for CRC as well as a therapeutic target, providing that upcoming studies confirm these results.
转录因子参与细胞周期和细胞凋亡的调控,因此在不同肿瘤的发生中起着关键作用。活化 T 细胞核因子、胞浆 2(NFATc2)和过氧化物酶体增殖物激活受体γ(PPARG)转录因子在结直肠癌(CRC)的发生中起着重要作用。在本研究中,我们研究了 NFATc2 和 PPARG 基因的表达是否在 CRC 的发生过程中发生显著改变。我们在手术中从 CRC 患者收集了总共 47 个肿瘤样本和匹配的正常组织边缘。此外,我们还使用了三个 CRC 细胞系(HCT119、SW480 和 HT29)和健康细胞系。提取总 RNA 并合成 cDNA 后,通过实时聚合酶链反应检测 NFATc2 和 PPARG 的 mRNA 表达水平。结果表明,与正常组织边缘相比,肿瘤组织中 NFATc2 过度表达(p ≤ 0.05)。然而,肿瘤组织和组织边缘之间的 PPARG mRNA 表达水平没有显著差异。我们的结果表明,NFATc2 可以作为 CRC 的早期诊断或预测生物标志物以及治疗靶点,前提是即将进行的研究能够证实这些结果。
