Abstract:
COL3A1 plays an oncogenic role in several types of cancer; however, the function of COL3A1 in gastric cancer (GC) remains unknown. The present study investigated the function and possible molecular mechanisms of COL3A1 in GC. The results showed that COL3A1 mRNA and protein were overexpressed in GC tissues and cells, and is associated with Immune microenvironment remodeling. High COL3A1 expression indicates poor prognosis. ESR1 transcriptionally elevates COL3A1 expression in GC. COL3A1-integrin α1 autocrine and paracrine axis promotes the proliferation, invasion, and angiogenesis of GC by activating PI3K-AKT signaling pathway. Targeting COL3A1 could significantly inhibit GC growth in vivo. Collectively, our findings indicated that COL3A1 could act as an oncogene in GC through regulating the PI3K-AKT signaling pathway.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Gastritis III: Clinical Manifestations and Management
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
Cancer-Critical Genes I: Proto-oncogenes
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.
Such genes that act...
