Summary
This summary is machine-generated.DEAD-box RNA helicase 19A (DDX19A) promotes gastric cancer growth and spread. It stabilizes PIK3CA mRNA, activating the PI3K/AKT pathway, leading to increased cell proliferation and migration.
Area Of Science
- Oncology
- Molecular Biology
- Biochemistry
Background
- DEAD-box RNA helicase 19A (DDX19A) is overexpressed in cervical squamous cell carcinoma.
- The role of DDX19A in gastric cancer pathogenesis is currently unknown.
Purpose Of The Study
- To investigate the role and underlying mechanism of DDX19A in gastric cancer development.
Main Methods
- Quantitative PCR, Western blotting, and immunohistochemistry were used to assess DDX19A expression.
- Cell proliferation, colony formation, and migration assays were employed to evaluate DDX19A's biological functions.
- Mechanism studies involved Western blotting, RNA immunoprecipitation, mRNA half-life assays, and RNA isolation.
Main Results
- DDX19A is highly expressed in gastric cancer, correlating with adverse clinicopathological features and poor prognosis.
- DDX19A enhances gastric cancer cell proliferation, migration, and epithelial-mesenchymal transition.
- DDX19A upregulates PIK3CA expression, stabilizing its mRNA and promoting nuclear export, thereby activating the PI3K/AKT pathway.
Conclusions
- DDX19A promotes gastric cancer cell proliferation and migration through a novel mechanism.
- This mechanism involves enhancing PIK3CA mRNA stability and nuclear export.
- Activation of the PI3K/AKT pathway by DDX19A contributes to gastric cancer progression.

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...
