Exosomes, being extracellular vesicles, are produced by the process of endocytosis. Cell-to-cell communication and the modulation of skin diseases' pathological and physiological processes are fundamentally influenced by exosomes, which transport biomolecules like enzymes, proteins, RNA, lipids, and cellular waste. A crucial component of the human body, skin, is approximately 8% of the total body mass. The body's outer surface is comprised of three distinct layers: the epidermis, dermis, and hypodermis, which constitute this organ. The distinction between exosomes and nanoparticles/liposomes lies in the former's inherent heterogeneity and endogeneity, a characteristic that has contributed to their extensive application in the treatment of dermatological issues. Many health researchers have taken notice of the biocompatible nature found in these extracellular vesicles. The following review article will first examine the creation of exosomes, their internal makeup, diverse isolation methods, and a nuanced assessment of the benefits and drawbacks of employing exosomes. Following this, key developments in the therapeutic use of exosomes for skin ailments like atopic dermatitis, alopecia, epidermolysis bullosa, keloids, melanoma, psoriasis, and systemic sclerosis will be examined.
Finding a potent and secure anticancer medication is now a major undertaking. Conventional therapy's unidirectional toxicity often leads to premature death in cancer patients with compromised health. From the dawn of humanity, plants have been utilized for medicinal purposes, and extensive scientific inquiry into the anticancer activities of various bioactive plant molecules persists. Research on cancer has repeatedly shown that pentacyclic triterpenoids, secondary plant metabolites, possess demonstrably cytotoxic and chemo-preventive capabilities. Triterpenoids belonging to the lupane, oleanane, and ursane families have been extensively studied recently for their possible antitumor properties. An exploration of the molecular mechanisms underlying the anticancer properties of plant-derived triterpenes is presented in this review. Antiproliferative activity, apoptosis induction via BCL2 and BH3 family protein regulation, inflammatory pathway modulation, cell invagination interference, and metastasis inhibition are the highlighted mechanisms. Solubility limitations in commonly utilized biological solvents are the primary obstacle hindering the therapeutic advancement of these triterpenoids. This review elucidates probable mitigation strategies for this issue, encompassing nanotechnology and alterations in their physical forms.
Long intergenic non-coding RNA-p21 (lincRNA-p21) is centrally important to the wide array of senescence-related physiological and pathological occurrences. The senescence-related effects of lincRNA-p21 in 1-methyl-4-phenylpyridinium (MPP+) treated neuroblastoma SH-SY5Y cells were explored, with an emphasis on its potential as a therapeutic target.
Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) served as the method for determining the RNA expression levels of lincRNA-p21, p53, p16, and telomere length. Employing the Telo TAGGG Telomerase PCR ELISA PLUS Kit, telomerase activity was assessed. Cellular viability was quantified using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and, in parallel, the lactate dehydrogenase (LDH) assay. Western blot analysis was employed to ascertain the expression levels of -catenin protein. Furthermore, oxidative stress was assessed using the J-aggregate-forming delocalized lipophilic cation, 55',66'-tetrachloro-11',33'-tetraethylbenzimidazolocarbocyanine++ iodide (JC1) stain, fluorescence spectroscopy, colorimetric methods, and malondialdehyde (MDA) production.
The application of MPP+ significantly increased the expression of LincRNA-p21 in the SH-SY5Y cell line, as this research demonstrated. Senescence of cells, driven by MPP+ exposure, presented with diminished cellular proliferation and viability, elevated expression of markers like p53 and p16 associated with senescence, and a substantial reduction in telomere length and telomerase activity. These effects were simultaneously counteracted by silencing lincRNA-p21 with small interfering RNA (siRNA). In opposition, the decrease in β-catenin expression contributes to the reversal of anti-senescent effects caused by the silencing of lincRNA-p21. Furthermore, the manipulation of lincRNA-p21 showed an anti-senescence impact, conditioned by the decrease in oxidant stress.
LincRNA-p21, as indicated by our study on MPP+ treatment, appears to influence SH-SY5Y cell senescence through modification of the Wnt/-catenin pathway and a concomitant rise in oxidative stress levels. For this reason, the exploration of lincRNA-p21 as a therapeutic focus for Parkinson's disease holds considerable therapeutic and practical import.
Our investigation into MPP+ treatment revealed a potential role for lincRNA-p21 in SH-SY5Y cell senescence, impacting the Wnt/-catenin pathway and exacerbating oxidative stress. Consequently, the pursuit of lincRNA-p21 as a therapeutic target in Parkinson's disease holds significant promise for both practical and clinical benefits.
