Comparison of p53 Protein Expression between Oral Squamous Cell Carcinoma and Verrucous Carcinoma

RUHS Journal of Health Sciences, 2023
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

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

Molecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Autophagy gene haploinsufficiency drives chromosome instability, increases migration, and promotes early ovarian tumors. [PDF]

, 2020
Autophagy, particularly with BECN1, has paradoxically been highlighted as tumor promoting in Ras-driven cancers, but potentially tumor suppressing in breast and ovarian cancers.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Breast Cancer Therapy by Small-Molecule Reactivation of Mutant p53

Current Oncology
Tumor suppressor p53 is essential for maintaining DNA stability and preventing cancer. Under normal conditions, the p53 protein is either degraded or bound to a negative regulator, rendering it inactive, but when DNA damage occurs, p53 is activated ...

Clinical applications of detecting dysfunctional p53 tumor suppressor protein.

Histology and histopathology, 1999
The p53 gene encodes for a protein, p53, which plays a critical role in controlling the cell cycle, in DNA repair and in programmed cell death (apoptosis). p53 is one of the most frequently mutated genes in human neoplasms and a variety of techniques have been developed to detect these mutations.

The p53 tumor suppressor protein regulates hematopoietic stem cell fate [PDF]

Journal of Cellular Physiology, 2011
AbstractThe p53 tumor suppressor protein is a key transcription factor that regulates several signaling pathways involved in the cell's response to stress. Through stress‐induced activation, p53 accumulates and triggers the expression of target genes that protect the genetic integrity of all cells including hematopoietic stem cells (HSCs).

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

New therapeutic strategies to treat human cancers expressing mutant p53 proteins

Journal of Experimental & Clinical Cancer Research, 2018
The tumor suppressor p53 plays a critical role to preserve DNA fidelity from diverse insults through the regulation of cell-cycle checkpoints, DNA repair, senescence and apoptosis. The TP53 is the most frequently inactivated gene in human cancers.

P53 mutations in human adrenocortical neoplasms [PDF]

, 1994
The mechanisms of tumorigenesis of adrenocortical neoplasms have not been elucidated as yet. However, loss of heterozygosity at chromosomal locus 17p has been consistently observed in adrenocortical cancer.
