Aim:
To determine the expression and significance of filamin A (FLNa) in colorectal adenocarcinoma tissue.
Methods:
The expression of FLNa in 46 colorectal cancer tissues and normal tissues was detected by immunohistochemistry, reverse transcription polymerase chain reaction (RT-PCR) and Western blotting, and its relationship with clinical parameters and prognosis was analyzed.
Results:
The positive expression of FLNa in cancer tissues was lower than that in normal mucosa, and the difference was statistically significant. The expression of FLNa correlated with liver metastasis, lymph node metastasis and rectal invasion depth, regardless of sex, age, tumor location, tumor size, gross shape and histological type of colorectal carcinoma. Multivariate analysis showed that FLNa was an independent risk factor for postoperative survival of patients with colorectal adenocarcinoma. Moreover, survival analysis showed that the expression level of FLNa was closely related with survival of patients with colorectal adenocarcinoma. The results of RT-PCR and Western blotting were consistent with those of immunohistochemistry.
Conclusion:
FLNa showed low expression in colorectal adenocarcinoma, high correlation with the incidence and development of colorectal cancer, and was considered an indicator of prognosis.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
