Summary: This study reveals the cooperative role of PAF1 and YAP1 in the development of pancreatic cancer and identifies verteportin and CA3 as inhibitors that target the PAF1/YAP1/SOX9 axis to inhibit cancer cell growth.

Summary: This study evaluated the effect of CDKN2A loss on EHE tumorigenesis. The loss of CDKN2A enhanced the invasiveness of EHE, leading to earlier tumor-related morbidity/mortality and increased tumor cell proliferation. Additionally, the study successfully established the first EHE cell lines, which replicated the transcriptional profile of EHE and generated EHE tumors in immunodeficient mice.

Summary: The study reveals that SHOX2 is strongly associated with poor distant metastasis-free survival in breast cancer patients, and its inactivation suppresses breast tumor growth and metastasis in mice. SHOX2 directly activates WASF3 gene in breast cancer cells by activating STAT3 and recruiting it to the WASF3 promoter, promoting metastatic potential. Targeting the SHOX2-STAT3-WASF3 signaling axis may represent a valuable alternative strategy for combating breast cancer metastasis.

Summary: NPM1 is overexpressed in prostate cancer cells and promotes proliferation by upregulating c-Myc expression. NPM1 cooperates with BRD4 to influence c-Myc transcription and facilitate prostate cancer progression. Blocking the NPM1-c-Myc oncogenic pathway may be a therapeutic strategy for prostate cancer.

Summary: Autophagy is a fundamental mechanism for cell survival and tissue homeostasis, and TRIM27 has been identified as a negative regulator of the FIP200-ATG13-ULK1 complex. TRIM27 controls the amplitude and duration of autophagy by ubiquitinating ULK1, and the ubiquitination of STK38L kinase plays a key role in ULK1 activation and phosphorylation.

Summary: Neutrophil elastase (NE) plays a role in promoting tumorigenesis by triggering ERK signaling and cell migration in prostate cells. NE stimulates the release of amphiregulin to initiate EGFR-dependent signaling. In prostate cancer cells, NE-mediated migration shifts from EGFR dependence to AXL dependence, suggesting the potential use of combined EGFR and AXL targeted therapy in prostate cancer treatment.

Summary: The study demonstrated the critical role of MKL1 in AAA, showing that its deficiency can reduce the risk of AAA formation and aortic rupture, as well as decrease aging and pro-inflammatory effects in the vessel wall and VSMCs. This research revealed a molecular pathway of AAA formation involving MKL1/p38MAPK stimulation, suggesting that targeting the MKL1/p38MAPK pathway may be an effective treatment for AAA.

Summary: This study demonstrates the tumor suppressor role of RSK2 in the liver and shows that its inactivation specifically synergizes with AXIN1 inactivation or β-catenin activation to promote the development of HCC with similar transcriptomic profiles as found in humans. Furthermore, this study highlights that activation of the RAS/MAPK pathway is one of the key signaling pathways mediating the oncogenic effect of RSK2 inactivation that can be targeted with already available anti-MEK therapies.

Summary: Aberrant expression of PLK4 has been linked to various malignancies with implications in centrosome amplification, aneuploidy, and genomic instability. It has been found that overexpression of PLK4 in human HCC is associated with poor patient prognosis, and induced expression of PLK4 can promote the migration and invasion of HCC cells. Additionally, TEC tyrosine kinase phosphorylates PLK4 to stabilize the protein and enhance HCC cell invasion.

Summary: The study reveals the physical and functional interaction between CP190 and M1BP in activating transcription at TAD borders and mediating chromatin insulator-dependent genome organization. M1BP and CP190 cooperatively promote gene expression and chromatin binding at TAD boundaries, influencing genome structure.

Summary: The study identifies DLX5 as a significant SCC-promoting factor, showing a distinct bivalent reconfiguration of its promoter in normal tissues versus cancer, where it is co-regulated by SOX2 in ESCC. Silencing of DLX5 significantly inhibits SCC viability and collaborates with TP63 to regulate thousands of enhancers and promoters, activating cancer-promoting pathways.
