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

open access: yesMolecular 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 ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Translation initiation or elongation inhibition triggers contrasting effects on Caenorhabditis elegans survival during pathogen infection

open access: yesmBio
Diverse microbial pathogens are known to attenuate host protein synthesis. Consequently, the host mounts a defense response against protein translation inhibition, leading to increased transcript levels of immune genes.

Mechanisms establishing TLR4-responsive activation states of inflammatory response genes. [PDF]

open access: yesPLoS Genetics, 2011
Precise control of the innate immune response is required for resistance to microbial infections and maintenance of normal tissue homeostasis. Because this response involves coordinate regulation of hundreds of genes, it provides a powerful biological ...

IAA3-mediated repression of PIF proteins coordinates light and auxin signaling in Arabidopsis.

open access: yesPLoS Genetics, 2021
The exogenous light signal and endogenous auxin are two critical factors that antagonistically regulate hypocotyl growth. However, the regulatory mechanisms integrating light and auxin signaling pathways need further investigation.

Alternative polyadenylation couples to transcription initiation: Insights from ELAV-mediated 3' UTR extension

open access: yes, 2015
Transcription initiation and mRNA maturation were long considered co-occurring but separately regulated events of gene control. In the past decade, gene promoters, the platforms of transcription initiation, have been assigned additional functions such as

Cloning, expression and characterization of the human transcription elongation factor, TFIIS [PDF]

open access: yesNucleic Acids Research, 1991
The cDNA for the human elongation factor, TFIIS, has been cloned and expressed in E. coli with the T7 expression system. This 280-amino acid TFIIS protein is shorter by 21 residues than that of the mouse. The missing 21 residues are located in the amino-terminal region, which is not thought to be required for transcriptional stimulation.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

CDK12/CDK13 inhibition disrupts transcriptional elongation and replication fork progression in glioblastoma

open access: yesEMBO Molecular Medicine
Glioblastomas are the most prevalent and aggressive malignant brain tumors, characterized by hypertranscription and dependence on neurodevelopmental transcription factors. The transcriptional cycle is regulated by phosphorylation of the C-terminal domain

Clinical performance of the urine‐based TERT promoter AbsoluteQ Digital PCR for non‐invasive detection of bladder cancer

open access: yesMolecular Oncology, EarlyView.
A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.
