Area Of Science
- Oncology
- Molecular Biology
- Cellular Signaling
Background
- Oxidative stress is implicated in cancer development, but its regulation in gastric cancer is not fully understood.
- Prohibitin 2 (PHB2) is upregulated in gastric cancer, correlating with poor prognosis and increased tumorigenicity.
Purpose Of The Study
- To elucidate the role of Prohibitin 2 (PHB2) in regulating oxidative stress and malignant progression in gastric cancer.
- To investigate the molecular mechanisms by which PHB2 influences gastric cancer pathogenesis.
Main Methods
- Investigated the correlation between PHB2 expression and the ERK/MAPK pathway activation.
- Examined the interaction of PHB2 with transcription factor C/EBP-beta and its effect on NADPH oxidase 1 (NOX1) transcription.
- Assessed the impact of PHB2 on cytosolic reactive oxygen species production and subsequent ERK activation.
Main Results
- PHB2 expression positively correlates with the activation of the ERK/MAPK cascade and the expression of NOX1.
- PHB2 enhances NOX1 transcription by facilitating C/EBP-beta nuclear translocation, leading to increased cytosolic reactive oxygen species.
- Elevated NOX1-driven oxidative signaling activates ERK, promoting gastric cancer progression.
Conclusions
- PHB2 is a key regulator of cytosolic reactive oxygen species production in gastric cancer via the C/EBP-beta-NOX1-ERK axis.
- Targeting the PHB2-mediated oxidative stress pathway presents a potential therapeutic strategy for gastric cancer.

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...
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 mTOR pathway or the...
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...
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
