Pyramidalization of the Glycosidic Nitrogen Provides the Way for Efficient Cleavage of the N‑Glycosidic Bond of 8‑OxoG with the hOGG1 DNA Repair Protein [PDF]

, 2012
A mechanistic pathway for cleavage of the N-glycosidic bond of 8-oxo-2′-deoxyguanosine (oxoG) catalyzed with the human 8-oxoguanine glycosylase 1 DNA repair protein (hOGG1) is proposed in this theoretical study. The reaction scheme suggests direct proton

ANKZF1 helps to eliminate stress-damaged mitochondria by LC3-mediated mitophagy

Cell Death Discovery
Mitochondria, the double membrane-bound organelles of endosymbiotic origin, are crucial centers for cellular energy production and several essential metabolic pathways.

Genome instability and loss of protein homeostasis: converging paths to neurodegeneration?

Open Biology, 2021
Genome instability and loss of protein homeostasis are hallmark events of age-related diseases that include neurodegeneration. Several neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease and amyotrophic ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Melanocortins and agouti-related protein modulate the excitability of two arcuate nucleus neuron populations by alteration of resting potassium conductances [PDF]

, 2007
The hypothalamic melanocortin system is crucial for the control of appetite and body weight. Two of the five melanocortin receptors, MC3R and MC4R are involved in hypothalamic control of energy homeostasis, with the MC4R having the major influence. It is

Regulation of Age-Related Protein Toxicity

Frontiers in Cell and Developmental Biology, 2021
Proteome damage plays a major role in aging and age-related neurodegenerative diseases. Under healthy conditions, molecular quality control mechanisms prevent toxic protein misfolding and aggregation.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Smurfs in Protein Homeostasis, Signaling, and Cancer [PDF]

Frontiers in Oncology, 2018
Protein ubiquitination is an evolutionary conserved highly-orchestrated enzymatic cascade essential for normal cellular functions and homeostasis maintenance. This pathway relies on a defined set of cellular enzymes, among them, substrate-specific E3 ubiquitin ligases (E3s). These ligases are the most critical players, as they define the spatiotemporal

TRIM16 controls turnover of protein aggregates by modulating NRF2, ubiquitin system, and autophagy: implication for tumorigenesis

Molecular & Cellular Oncology, 2018
Protein misfolding and protein aggregation are linked to several diseases commonly called as proteinopathies, which include cancer. Understanding the mechanisms of proteostasis could provide newer strategies to combat proteinopathies.
