SNHG7 and FAIM2 are up-regulated and co-expressed in colorectal adenocarcinoma tissues


Klin Onkol 2020; 33(6): 445-449. DOI: 10.48095/ccko2020445.

Background: The global incidence of colorectal cancer (CRC) is expected to be increased by 60% until a few years. Despite the advances in surgical and chemotherapy techniques, a significant proportion of patients with CRC have poor responses to treatments. These are the reasons that prove the importance of identifying molecular bio­markers as potential therapeutic targets. Long non-coding RNAs (lnc RNAs) participate in the initiation, development, progression, and metastasis of cancers such as CRC. Hence, this class of noncoding RNAs is known as bio­marker for cancer dia­gnosis and prognosis. Materials and methods: In this experimental study, the extraction of total RNA from tissues, synthesis of complementary DNA as well as quantitative real-time polymerase chain reaction (qRT- PCR) were performed. Comparative cycle threshold method was applied to quantify the expression level of lncRNA-SNHG7 and FAIM2. The relative amount of lncRNA-SNHG7 and FAIM2 was calculated using the equation 2 -DDCT. Results: In this study, by qRT PCR, we concluded that the expression level of SNHG7, as a recently identified lncRNA and FAIM2 were increased in colorectal cancer tissues compared with normal adjacent tissues. Conclusion: Our study indicates the potential importance of SNHG7 and FAIM2 expression for more studies in future.
