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

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 bio-markers 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 bio-marker for cancer dia-gnosis and prognosis.

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.

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.

Our study indicates the potential importance of SNHG7 and FAIM2 expression for more studies in future.
