JARID2 (Jumonji And AT-Rich Interaction Domain Containing 2)

Taken together, these findings highlight JARID2 inhibition as a novel and reversible approach to expand functional UCB-derived HSPCs ex vivo, potentially improving access to stem cell transplantation for a wider patient population. Genetic inhibition of JARID2 enhances repopulating activity of human hematopoietic stem and progenitor cells in vivo via STAT1 upregulation.

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.

DNA methylation profiles differ profoundly at two points: tumor to case-benign and case-benign to HDB, with clear distinction between ER + and ER- tumors. Case-benign tissues are not epigenetically "normal", are similar across both breasts, and do not differ by ER status of paired tumors.

In addition, miR-155-5p inactivated the TGFβ/SMAD2 pathway by negatively regulating JARID2 expression. In conclusion, miR-155-5p inhibits MM cell malignancy and tumorigenesis by targeting JARID2 and inactivating the TGFβ/SMAD2 signaling.

Our findings suggest that NAT10-mediated acetylation of JARID2 mRNA up-regulates its protein levels, thereby promoting stemness and contributing to the malignancy of GBM. Targeting this NAT10-JARID2 axis may represent a novel therapeutic approach for treatment of GBM.

Mutation of components of the Polycomb Repressor Complex 2 rescued proliferation inhibition caused by the CDK4/6 inhibitor palbociclib, but not to inhibitors of S phase or mitosis...This included the CpG islands in the promoter of the CDK4/6 cyclins CCND1 and CCND2, and loss of MTF2 lead to upregulation of both CCND1 and CCND2. Our results demonstrate a role for PRC2.1, but not PRC2.2, in antagonizing G1 progression in a diversity of cell linages, including chronic myeloid leukemia (CML), breast cancer, and immortalized cell lines.

Taken together, the study has confirmed that JARID2 acts as a tumor suppressor, the downregulation of which promotes OSCC progression by regulating Epithelial-to-Mesenchymal Transition (EMT). The online version contains supplementary material available at 10.1007/s13205-024-04163-8.

Knockdown of JARID2 inhibited tumor growth and cell stemness in mice but was alleviated by concurrent overexpression of NFYA. NFYA promotes TNBC cell stemness by upregulating JARID2 expression and regulating the PI3K/AKT signaling pathway, suggesting JARID2 as a potential target for innovating drugs that target TNBC stem cells.

To the best of our knowledge, the E3 ubiquitin ligase TRIM22 was first reported as a tumor suppressor that inhibits the proliferation and invasion of breast cancer cells through CCS ubiquitination and degradation. TRIM22 is a potential prognostic biomarker in patients with breast cancer.

Our study indicates that JARID2 is a novel prognostic biomarker and potential therapeutic target for OSCC.

Additionally, Tfcp2l1 can replicate the hypoxic effect of increasing cellular reprogramming. Altogether, our data suggest that the activation of Tfcp2l1 by hypoxia contributes to immortalization prior to malignant transformation, facilitating tumorigenesis and dedifferentiation by regulating Sox2, Sox9, and Jarid2.

We identified a set of 9 miRNAs that are significantly deregulated in large VS in comparison to small, intracanalicular tumors. The functional enrichment analysis of these miRNAs suggests novel mechanisms, such as that lipid metabolism, as well as Hippo and FOxO signaling pathways that may play an important role in VS growth regulation.
