ADP-ribosylation (ADPRylation) is a posttranslational modification of proteins discovered nearly six decades ago, but many important questions remain regarding its molecular functions and biological roles, as well the activity ADP-ribose (ADPR) transferase enzymes (PARP family members) that catalyze it. Growing evidence indicates PARP-mediated ADPRylation events are key regulators protein biosynthetic pathway, leading from rDNA transcription ribosome biogenesis to mRNA synthesis, processing, translation. In this review we describe role PARP in all facets pathway. PARP-1 enzymatic transcription, which critical step biogenesis. An emerging PARPs alternative splicing mRNAs, direct highlight members RNA processing. Furthermore, activity, stimulated by cellular stresses, such viral infections ER stress, leads regulation stability synthesis through posttranscriptional mechanisms. Dysregulation these processes can promote disease states. Collectively, results importance gene regulation, abundance. Future studies areas will yield new insights into fundamental mechanisms broader utility for PARP-targeted therapeutic agents.

Abstract Human longevity has increased dramatically during the past century. More than 20% of 9 billion population world will exceed age 60 in 2050. Since last three decades, some interventions and many preclinical studies have been found to show slowing aging increasing healthy lifespan organisms from yeast, flies, rodents nonhuman primates. The are classified into two groups: lifestyle modifications pharmacological/genetic manipulations. Some genetic pathways characterized a specific role controlling lifespan. Thus, all genes potential antiaging targets. Currently, compounds target calorie-restriction mimetic, autophagy induction, putative enhancement cell regeneration, epigenetic modulation gene activity such as inhibition histone deacetylases DNA methyltransferases, under development. It appears evident that exploration new targets for these agents based on biogerontological research provides an incredible opportunity healthcare pharmaceutical industries. present review focus properties slow life span extension natural products various biological resources, endogenous substances, drugs, synthetic compounds, well mechanisms evaluation. These bioactive could benefit discussed.

Autophagy is an intracellular degradation pathway that recycles subcellular components to maintain metabolic homeostasis. NAD essential metabolite participates in energy metabolism and serves as a substrate for series of NAD+-consuming enzymes (NADases), including PARPs SIRTs. Declining levels autophagic activity represent features cellular ageing, consequently enhancing either significantly extends health/lifespan animals normalises cells. Mechanistically, it has been shown NADases can directly regulate autophagy mitochondrial quality control. Conversely, preserve by modulating stress. In this review we highlight the mechanisms underlying bidirectional relationship between autophagy, potential therapeutic targets provides combatting age-related disease promoting longevity.

Alzheimer's disease (AD) is associated with metabolic abnormalities linked to critical elements of neurodegeneration. We recently administered combined activators (CMA) the AD rat model and observed that CMA improves AD-associated histological parameters in animals. promotes mitochondrial fatty acid uptake from cytosol, facilitates oxidation mitochondria, alleviates oxidative stress.

Abstract Mitochondria, the most crucial energy-generating organelles in eukaryotic cells, play a pivotal role regulating energy metabolism. However, their significance extends beyond this, as they are also indispensable vital life processes such cell proliferation, differentiation, immune responses, and redox balance. In response to various physiological signals or external stimuli, sophisticated mitochondrial quality control (MQC) mechanism has evolved, encompassing key like biogenesis, dynamics, mitophagy, which have garnered increasing attention from researchers unveil specific molecular mechanisms. this review, we present comprehensive summary of primary mechanisms functions regulators involved major components MQC. Furthermore, critical regulated by MQC its diverse roles progression systemic diseases been described detail. We discuss agonists antagonists targeting MQC, aiming explore potential therapeutic research prospects enhancing stabilize function.
