Emerging insights in senescence: pathways from preclinical models to therapeutic innovations.

Senescence is a crucial hallmark of ageing and a significant contributor to the pathology of age-related disorders. As committee members of the young International Cell Senescence Association (yICSA), we aim to synthesise recent advancements in the identification, characterisation, and therapeutic targeting of senescence for clinical translation. We explore novel molecular techniques that have enhanced our understanding of senescent cell heterogeneity and their roles in tissue regeneration and pathology.

Water Extracts of Leaves Alter Oxidative Stress-Induced Neurotoxicity in Human Neuroblastoma SH-SY5Y Cells.

(MO) has been an important plant for food and traditional medicine in Asian countries, including Indonesia. The leaves of these plants are reported to be rich in antioxidants, vitamins, and micronutrients and have been proven to have nootropic properties. Therefore, we investigated whether MO could provide protective effects on SH-SY5Y neuroblastoma cells exposed to HO.

Repurposing effect of cardiovascular-metabolic drug to increase lifespan: a systematic review of animal studies and current clinical trial progress.

With the increase in life expectancy, aging has emerged as a significant health concern. Due to its various mechanisms of action, cardiometabolic drugs are often repurposed for other indications, including aging. This systematic review analyzed and highlighted the repositioning potential of cardiometabolic drugs to increase lifespan as an aging parameter in animal studies and supplemented by information from current clinical trial registries.

Comparative Neuroprotective Effects of Seed Oil and Aqueous Extract on Cognitive Functions on a High-Fat, High-Fructose Diet Mice: Focus on Senescence Markers.

Several studies have demonstrated that (MO) has different pharmacological properties, including neuroprotective effects. However, the role of MO in preventing brain impairment in high-fat, high-fructose diet (HFFD) remains unknown. This study aimed to investigate the neuroprotective effects of MO leaves aqueous extract (MOE) and moringa seed oil (MOO) against brain impairment in mice with HFFD.

The Oil Formulation Derived from Seeds Ameliorates Behavioral Abnormalities in Water-immersion Restraint Stress Mouse Model.

Purpose: Repeated stress events are well known to be associated with the onset of behavioral abnormalities including depression, anxiety and memory impairment. In spite of the traditional uses of (MO), no experimental evidence for its use against chronic stress exists. Here, we investigated whether seed oil from MO (MOO) could improve behavior abnormalities of chronic stress mice induced by water-immersion restraint stress (WIRS) and the underlying mechanism.

Protective effects of silver nanoparticles in isoproterenol-induced myocardial infarction in rats.

Background: Silver nanoparticles (AgNPs) are widely used in the medical field, including cardiovascular. However, limited research has investigated the effect of AgNPs on the protection of myocardial infarction (MI).

Objectives: Isoproterenol (Iso)-induced MI and the cardiac protection offered by AgNPs were investigated in the present study.

Pilot Study on the Effect of a Single Topical Application of Trichloroacetic Acid 85% on Normal Cervical Tissue.

Early detection and treatment of cervical intraepithelial neoplasia (CIN) through a "see and treat" approach is a pillar of cervical cancer prevention programs in developing countries such as Indonesia. One of the major challenges faced is the limited NO or CO gas supply for cryotherapy. Thus, an alternative therapeutic method such as trichloroacetic acid (TCA) topical application is needed as an alternative solution.

Curcumin Prevents Epithelial-to Mesenchymal Transition-Mediated Ovarian Cancer Progression through NRF2/ETBR/ET-1 Axis and Preserves Mitochondria Biogenesis in Kidney after Cisplatin Administration.

Ovarian carcinoma is one of the gynaecological malignancies that have the highest mortality rates due to its progressivity. Endothelin signalling plays a leading role in the progression of ovarian cancer through Epithelial-to-Mesenchymal Transition (EMT). Cisplatin commonly used as potent chemotherapy; however, its application hindered by its nephrotoxic effect.

Effects of in Two Independents Formulation and as Neuroprotective Agent Against Scopolamine-Induced Memory Impairment in Mice.

Background: The cognitive deficit has frequently been found in the elderly population. Several studies have shown that every single part of , including leaves, roots, and seeds, has abundant micronutrients, such as flavonoids, which improve the neurobehavioral capacity. However, herb parts that display optimal neuropharmacological properties remain unknown.

Endothelial progeria induces adipose tissue senescence and impairs insulin sensitivity through senescence associated secretory phenotype.

Vascular senescence is thought to play a crucial role in an ageing-associated decline of organ functions; however, whether vascular senescence is causally implicated in age-related disease remains unclear. Here we show that endothelial cell (EC) senescence induces metabolic disorders through the senescence-associated secretory phenotype. Senescence-messaging secretomes from senescent ECs induced a senescence-like state and reduced insulin receptor substrate-1 in adipocytes, which thereby impaired insulin signaling.

Neuregulin-4 is an angiogenic factor that is critically involved in the maintenance of adipose tissue vasculature.

Adipose tissue (AT) contains well-developed vascular networks. Pathological AT expansion often accompany the reduction in AT blood vessels, which further exacerbates adipocyte dysfunction due to hypoxia; however, it remains unclear whether AT vascular rarefaction is simply secondary to adipocyte hypertrophy, or if there is an actively regulated pathway that mediates impaired AT angiogenesis in obesity. We searched for growth factors whose expression in AT is down-regulated in obesity; accordingly, we identified neuregulin-4 (Nrg4), a member of the EGF family of proteins.

Systemic inhibition of Janus kinase induces browning of white adipose tissue and ameliorates obesity-related metabolic disorders.

Browning of white adipose tissue is a promising strategy to tackle obesity. Recently, Janus kinase (JAK) inhibition was shown to induce white-to-brown metabolic conversion of adipocytes in vitro; however effects of JAK inhibition on browning and systemic metabolic health in vivo remain to be elucidated. Here, we report that systemic administration of JAK inhibitor (JAKi) ameliorated obesity-related metabolic disorders.

Macrophages Highly Express Carbonic Anhydrase 2 and Play a Significant Role in Demineralization of the Ectopic Calcification.

Vascular calcification is an important risk factor for cardiovascular disease, and is closely associated with all-cause mortality. Recently, it has been revealed that vascular calcification is not a passive precipitation of circulating minerals, but is a process actively regulated through machinery similar to bone formation. During the bone remodeling, osteoclasts execute the bone resorption by releasing hydrogen ions to dissolve minerals; however, molecular mechanisms underlying decalcification of ectopically calcified lesions remain largely unknown.

Family with sequence similarity 13, member A modulates adipocyte insulin signaling and preserves systemic metabolic homeostasis.

Adipose tissue dysfunction is causally implicated in the impaired metabolic homeostasis associated with obesity; however, detailed mechanisms underlying dysregulated adipocyte functions in obesity remain to be elucidated. Here we searched for genes that provide a previously unknown mechanism in adipocyte metabolic functions and identified family with sequence similarity 13, member A (Fam13a) as a factor that modifies insulin signal cascade in adipocytes. Fam13a was highly expressed in adipose tissue, predominantly in mature adipocytes, and its expression was substantially reduced in adipose tissues of obese compared with lean mice.
