VASH2 (Vasohibin 2)

Moreover, we demonstrate that the observed phenotypes are caused by the accumulation of the important epithelial marker E-cadherin with simultaneous reduction in mesenchymal markers N-cadherin and vimentin. Taken together, our study establishes tubulin detyrosination as a promising target for the future development of anticancer treatment.

Additionally, KY216 elevates the levels of miR-429 to target the 3'-untranslated region (3' UTR) of VASH2 and ZEB1 transcripts and inhibits EMT, at least partially, via the miR-429/VASH2/ZEB1 axis to block NSCLC metastasis. Overall, our investigation offers valuable insights into the roles of MTAs and VASH2 in NSCLC metastasis.

Enzyme kinetics, competition assays, and metal ion dependency studies confirmed the assay's specificity, robustness, and physiological relevance. This optimized assay provides a powerful and reliable tool for the future identification and characterization of inhibitors of α-tubulin detyrosination.

Specificity assessments against other cysteine proteases and incubations with nonspecific nucleophiles demonstrated that LV87 selectively targets VASH1/2. Additionally, safety data, serum, and microsome stability tests support the notion that LV87 is a selective and potent inhibitor of tubulin detyrosination, paving the way for further optimization and applications.

Taken together, these findings establish a specific mechanism by which LINC00654 interacts with HuR, facilitates its nuclear export, and stabilizes VASH2, thereby activating the TGF-β pathway and promoting OC progression. This insight into LINC00654's role in OC provides potential therapeutic targets for intervention.

This review explores the molecular properties of VASHs and their emerging functions in tubulin carboxyl activity and microtubule detyrosination-key to brain and cardiac remodeling. We also discuss the potential therapeutic applications of their interference in diseases such as tumorigenesis, as well as renal-, reproductive-, and liver-related diseases.

This study demonstrated that dynamic changes in VASH and NO signaling following tumor resection could serve as a potential indicator of tumor angiogenesis. Our findings suggest that the overall activity of the VASH pathway in leukocytes was reduced after tumor removal, highlighting the potential of leukocyte physiology as a novel biomarker for cancer surveillance and control.

Blocking the tubulin carboxypeptidase (TCP) activity of VASH2 inhibited the xenograft tumor growth and improved the treatment efficacy of paclitaxel in vivo. Results revealed that VASH2-induced increase in tubulin detyrosination boosted the binding of kinesin family member 3C (KIF3C) to microtubules and enhanced KIF3C-dependent endosomal recycling of EGFR, leading to the prolonged activation of PI3K/Akt/mTOR signaling. This study demonstrated that VASH2 was not only a prognostic biomarker but also a promising therapeutic target in LUSC, which offers a novel insight that combination of chemotherapy and EpoY, a TCP inhibitor, may be a promising treatment strategy for LUSC patients.

We found for the first time that the positive expression rate of VASH2 was closely associated with SHH-type pediatric medulloblastoma and that VASH2 was involved in the invasion, migration, cell cycle, and apoptotic capacity of SHH medulloblastoma cell lines DAOY by affecting downstream indicators of the TGF-β pathway. This suggests that it is involved in the progression of pediatric medulloblastoma, and VASH2 is expected to be a diagnostic and therapeutic target for SHH-type pediatric medulloblastoma.
