Summary
This summary is machine-generated.Myc-associated zinc finger protein (MAZ) drives gastric cancer (GC) by activating Laminin subunit alpha-5 (LAMA5) and the STAT3 pathway. Targeting the MAZ-LAMA5 axis offers a potential therapeutic strategy for GC.
Area Of Science
- Oncology
- Molecular Biology
- Cancer Research
Background
- Laminin subunit alpha-5 (LAMA5) is an oncogene in various cancers, but its specific role in gastric cancer (GC) is not fully understood.
- Investigating the molecular mechanisms underlying LAMA5's function in GC is crucial for developing targeted therapies.
Purpose Of The Study
- To explore the role and mechanism of LAMA5 in gastric cancer (GC) progression.
- To investigate the regulatory relationship between Myc-associated zinc finger protein (MAZ) and LAMA5 in GC.
- To evaluate the therapeutic potential of targeting the MAZ-LAMA5 axis in GC.
Main Methods
- LAMA5 expression was silenced in GC cells, with and without STAT3 activator Colivelin.
- In vitro assays included CCK-8, colony formation, EdU, flow cytometry, wound healing, and Transwell assays.
- In vivo studies assessed tumor growth. MAZ-LAMA5 interactions were analyzed using ChIP and luciferase reporter assays.
Main Results
- LAMA5 was highly expressed in GC cells, and its knockdown inhibited malignant aggressiveness.
- Colivelin treatment reversed the inhibitory effects of LAMA5 knockdown.
- MAZ directly bound to the LAMA5 promoter, activating its transcription.
- MAZ knockdown's anti-tumor effects were abrogated by LAMA5 overexpression.
Conclusions
- MAZ promotes GC cell proliferation and migration via the LAMA5/STAT3 axis.
- The MAZ-LAMA5/STAT3 axis represents a promising therapeutic target for gastric cancer.

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...
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 (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...
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
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...
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
