TLE3 (TLE Family Member 3, Transcriptional Corepressor)

Some variants appeared to segregate with specific types of lymphoid cancers; others were shared across different subtypes. Identifying factors predisposing to different types of lymphoid cancers will help understand the etiology of these neoplasms.

Our study demonstrated that NEK9 plays an important role in Docetaxel resistance. The novel combination of NEK9 inhibitor Fostamatinib and Docetaxel needs further clinical investigation in advanced OSCC.

Furthermore, we confirmed the prognostic significance of TMEM18 expression at the protein level with immunohistochemistry (IHC) in a primary PCa tumor cohort. In conclusion, we identified 85 mCRPC-associated genes and showed that TMEM18 has prognostic value in early PCa.

The patient was successfully treated with the JAK2 inhibitor ruxolitinib for 8 months before additional somatic mutations were acquired and the disease progressed into an acute lymphoblastic T-cell leukemia/lymphoma. The present case shows similarities to previously reported cases with PCM1::JAK2 and BCR::JAK2 with regard to disease phenotype and response to ruxolitinib, and importantly, provides an example that also patients harboring other JAK2 fusion genes may benefit from treatment with JAK2 inhibitors.

In summary, we have uncovered the protective role of PAPSS2-mediated chondroitin sulfation and bile acids-FXR-TLE3 activation in the prevention of gut carcinogenesis via the antagonization of Wnt/β-catenin signaling. Chondroitin sulfate may be explored as a therapeutic agent for Papss2 deficiency-associated colonic carcinogenesis.

A combination drug therapy regime to promote Wnt-pathway activation by the small molecule BIO and inhibit KMT1A by the drug chaetocin led to significantly reduced tumor volume, decreased proliferation, increased expression of differentiation markers and increased survival in rhabdomyosarcoma tumor-bearing mice. Thus, TLE3, the Wnt-pathway and KMT1A are excellent drug targets which can be exploited for treating rhabdomyosarcoma tumors.

We detected that the replacement of AR by GR in enzalutamide-exposed prostate cancer cells occurs almost exclusively at pre-accessible chromatin sites displaying FOXA1 occupancy...Moreover, the small-molecule inhibition of coactivator p300's enzymatic activity efficiently restricted GR-mediated gene regulation and cell proliferation. Overall, we identified chromatin pre-accessibility and FOXA1-mediated repression as important regulators of GR action in prostate cancer, pointing out new avenues to oppose steroid receptor-mediated antiandrogen resistance.

Nuclear localized HHEX bound to and upregulated TLE3 expression by preventing TLE3 protein from being distributed to the cytoplasm and being ubiquitinated. In conclusion, our study suggested that restoring HHEX expression has the potential to be a new strategy in the treatment of advanced thyroid cancer.

This study shows that TLE3-AKR1B1 signaling axis can participate in GIST malignant progression through regulation of galactose metabolism, providing experimental data for understanding the mechanism of GIST malignant progression from the perspective of metabolic reprogramming, and also providing a new target for GIST treatment.

These results establish TLE3 as an essential transcriptional repressor that sustains the more differentiated and less metastatic nature of luminal breast cancers. Approaches to induce TLE3 expression could promote the acquisition of less aggressive, more treatable disease states to extend patient survival.
