TEKT4 (Tektin 4)

Gene set enrichment analysis showed enriched pathways associated with cancer-related biological processes such as DNA repair and depleted pathways related to translation, cellular metabolic process, and mitochondrial functions. This study highlights that the distinctive genetic composition of underrepresented groups influences the penetrance of pathogenic variants that could contribute to hereditary cancer risk in ways that diverge from patterns observed in more extensively researched cohorts.

We established a diagnostic algorithm based on the methylation status of seven cg sites located in TETK4P2 (Tektin 4 Pseudogene 2), MYO1D (Myosin ID), and PMF1-BGLAP (PMF1-BGLAP Readthrough), which allows the distinction between SN and SM but is also capable of subclassifying AST according to their similarity to the methylation levels of Spitz nevi or spitzoid melanoma. Thus, our epigenetic algorithm can predict the risk level of AST and predict its potential clinical outcomes.

This study provides a comprehensive analysis of lncRNA m7G modification during the inflammatory-carcinogenesis transformation process in HBV-mediated HCC. The findings highlight the potential for multiple lncRNAs to undergo m7G modification changes, with TEKT4P2 and DNM1P41 identified as promising molecular targets within this intricate regulatory landscape.

Our bioinformatics analysis identified KCNJ18, GPRIN2, TEKT4, HRNR, FOLR3, ESSRA, CTBP2, MPRIP, TBP, and FBXO6 may contribute to progression in NSCLC and could be used as new biomarkers for the treatment. The mechanism by which GPRIN2, KCNJ12, and TEKT4 contribute to tumorigenesis is unclear, but our results suggest they may play an important role in NSCLC and it is worth investigating in future.

We conclude that the evaluation of CTSF gene mutations of patients in thyroid cancer families may be predictive and valuable for the familial heredity of thyroid cancer.

Significantly, we found that tektin4 loss sensitized TNBC cells, xenograft models, and patient-derived organoid models to the HDAC6-selective inhibitor ACY1215. Furthermore, tektin4 expression levels were positively correlated with microtubule stability levels in clinical samples. Together, our findings uncover a metastasis suppressor function of tektin4 and support clinical development of HDAC6 inhibition as a new therapeutic strategy for tektin4-deficient TNBC patients.

Although the primary endpoint was not met, NE might bring clinical benefit to HR-positive patients or patients simultaneously carrying UNC13D mutations.
