We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

A Second Career for p53 as A Broad-Spectrum Antiviral?
As the world exits the global pandemic caused by the previously unknown SARS-CoV-2, we also mark the 30th anniversary of p53 being named “molecule of the year” by Science based on its role as a tumor suppressor.

MITF maintains genome stability in nonmelanocyte lineages
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Immunohistochemistry Assessment of P53 Protein in Basal Cell Carcinoma
The most frequently mutated tumor suppressor gene found in human cancer is p53. In a normal situation, p53 is activated upon the induction of DNA damage to either arrest the cell cycle or else induce apoptosis.

Crucial role of TSC-22 in preventing the proteasomal degradation of p53 in cervical cancer. [PDF]
The p53 tumor suppressor function can be compromised in many tumors by the cellular antagonist HDM2 and human papillomavirus oncogene E6 that induce p53 degradation. Restoration of p53 activity has strong therapeutic potential. Here, we identified TSC-22

Comparison of p53 Protein Expression between Oral Squamous Cell Carcinoma and Verrucous Carcinoma
Introduction: Deletion or mutation of tumor suppressor genes plays a significant role in cancer development. Mutation of the p53 tumor suppressor gene is the most common genetic alteration associated with oral cancer. The aim of this study was to compare

Protein methylation: a new mechanism of p53 tumor suppressor regulation.
The tumor suppressor p53 is the most frequently inactivated gene in human cancers. The p53 protein functions as a sequence-specific transcription factor to regulate key cellular processes, including cell-cycle arrest, DNA repair, apoptosis, and senescence in response to stress signals.

The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Tumor suppressor protein p53 binds preferentially to supercoiled DNA [PDF]
Wild type human tumor suppressor protein p53 (expressed in insect cells) binds strongly to negatively supercoiled (sc) plasmid DNA at a native superhelix density, as evidenced by electrophoretic retardation of scDNA in agarose gels and imaging by scanning force microscopy (SFM).

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
