Diverse regulatory manners of human telomerase reverse transcriptase

Cell Communication and Signaling, 2019
Human telomerase reverse transcriptase (hTERT) is the core subunit of human telomerase and plays important roles in human cancers. Aberrant expression of hTERT is closely associated with tumorigenesis, cancer cell stemness maintaining, cell proliferation,

Post-translational Modification of Pregnane X Receptor [PDF]

, 2011
Pregnane x receptor (PXR, NR1I2) was originally characterized as a broad spectrum entero-hepatic xenobiotic ‘sensor’ and master-regulator of drug inducible gene expression.

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

Molecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Identification and characterization of O-GlcNAc modifications of a conserved orthopoxvirus core protein

Journal of Virology
O-GlcNAcylation, a post-translational modification consisting of O-linked N-acetylglucosamine attached to serine and threonine residues, occurs in thousands of cytoplasmic, nuclear, and mitochondrial proteins but has been reported for relatively few ...

Association and dissociation of the GlnK-AmtB complex in response to cellular nitrogen status can occur in the absence of GlnK post-translational modification

Frontiers in Microbiology, 2014
PII proteins are pivotal players in the control of nitrogen metabolism in bacteria and archaea, and are also found in the plastids of plants. PII proteins control the activities of a diverse range of enzymes, transcription factors and membrane transport ...

VDAC proteomics: Post-translation modifications

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2012
Voltage-dependent anion channels are abundant mitochondrial outer membrane proteins expressed in three isoforms, VDAC1-3, and are considered as "mitochondrial gatekeepers". Most tissues express all three isoforms. The functions of VDACs are several-fold, ranging from metabolite and energy exchange to apoptosis.

Post-translational mutagenesis: radical methods for protein modification

, 2017
The naturally occurring post-translational modification of proteins expands the chemical and structural diversity available for protein function. Enzymatic processes are known to modify proteins after translation, and in many cases these modifications ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.
