Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Cell-to-cell transmission of p53 aggregates: a novel player in oncology?

Molecular & Cellular Oncology, 2021
The mutants of the tumor suppressor protein p53 form protein aggregates. It has been proposed that these aggregates propagate like prions, albeit the detailed mechanism of the propagation is unclear.

p66α Suppresses Breast Cancer Cell Growth and Migration by Acting as Co-Activator of p53

Cells, 2021
p66α is a GATA zinc finger domain-containing transcription factor that has been shown to be essential for gene silencing by participating in the NuRD complex. Several studies have suggested that p66α is a risk gene for a wide spectrum of diseases such as

Oncogenic Gain of Function in Glioblastoma Is Linked to Mutant p53 Amyloid Oligomers. [PDF]

, 2020
Tumor-associated p53 mutations endow cells with malignant phenotypes, including chemoresistance. Amyloid-like oligomers of mutant p53 transform this tumor suppressor into an oncogene.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

A Second Career for p53 as A Broad-Spectrum Antiviral?

Viruses, 2023
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.

Active regulator of SIRT1 is required for cancer cell survival but not for SIRT1 activity [PDF]

, 2013
The NAD+-dependent deacetylase SIRT1 is involved in diverse cellular processes, and has also been linked with multiple disease states. Among these, SIRT1 expression negatively correlates with cancer survival in both laboratory and clinical studies ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Immunohistochemistry Assessment of P53 Protein in Basal Cell Carcinoma

Iranian Journal of Allergy, Asthma and Immunology, 2005
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]

PLoS ONE, 2012
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
