Area Of Science
- Oncology
- Molecular Biology
- Cancer Research
Background
- Pancreatic cancer incidence is rising with a low 5-year survival rate.
- Musashi2 (MSI2) promotes pancreatic cancer aggressiveness by downregulating Numb and p53.
- MSI2 facilitates epithelial-mesenchymal transition (EMT) via the ZEB1-ERK/MAPK pathway.
Purpose Of The Study
- To explore the molecular mechanisms of MSI2-regulated downstream pathways in pancreatic cancer.
- To investigate the role of the MSI2-NLK axis in pancreatic cancer progression.
Main Methods
- In vitro and in vivo experiments were conducted.
- Gene expression and protein correlation analysis using GEPIA and TCGA databases.
- Investigation of cell invasion, migration, EMT, and PI3K-AKT-mTOR pathway modulation.
- Analysis of MSI2's direct binding to NLK mRNA.
Main Results
- NLK mRNA levels significantly changed with MSI2 interference/overexpression and correlated with MSI2 at the protein level.
- Both MSI2 and NLK are independent adverse prognostic indicators for pancreatic cancer survival.
- MSI2 silencing inhibited invasion, migration, EMT, and liver metastasis, effects reversed by NLK overexpression.
- MSI2 directly binds to NLK mRNA, enhancing its activity and exerting post-transcriptional regulation.
Conclusions
- The MSI2-NLK axis modulates aggressive pancreatic cancer behaviors.
- Understanding these regulatory mechanisms provides new evidence for therapeutic strategies against pancreatic cancer.

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 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.

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...
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...
