TLDR
It is found that overexpression of lncRNA MEG3 could decrease the proliferation and metastasis of gastric cancer cells and could also increase the expression of p53.Abstract:
Objective lncRNA MEG3 has been reported as a tumor suppressor gene in many different kinds of cancer, but its role in gastric cancer has not been fully understood. Then, we would like to explore its mechanism in gastric cancer. Patients and methods We first used qRT-PCR to detect the expression of lncRNA MEG3, then CCK8 and wound healing assay were used to detect the effect of lncRNA MEG3 on gastric cancer cells. Western blot assay was used to measure the expression of p53 when lncRNA MEG3 was overexpressed. Results lncRNA MEG3 was highly expressed in the adjacent tissue, compared to the one in gastric cancer tissue. What's more, we also found that overexpression of lncRNA MEG3 could decrease the proliferation and metastasis of gastric cancer cells. Finally, overexpression of lncRNA MEG3 could also increase the expression of p53. Conclusions lncRNA MEG3 could inhibit the proliferation and metastasis of gastric cancer.read more

TL;DR: The immunohistochemical expression of the wnt/b-catenin pathway in oral carcinoma cells (OSCC) is demonstrated through a literature review and cancer stem cells, PON2 type enzymes, nicotine intake, cytokine TNF-α and FAD1 gene are able to increase growth and metastasis by inhibiting the same pathway.
