Platelet-Rich Plasma (PRP) Mitigates Kidney Dysfunction in Alloxan-Induced Diabetic Mice via Modulation of Renal Iron Regulatory Genes.

Kidney dysfunction is a prevalent complication of diabetes mellitus, contributing significantly to diabetes-related morbidity and mortality. We aim to explore whether platelet-rich plasma administration can modulate iron regulation mechanism within the kidney, thereby mitigating renal dysfunction associated with diabetes. Albino mice with an average body weight of 20 ± 5 g were randomly divided into five groups (N = 50; n = 10): Control Group, PRP Group, diabetic group (DG), treated group A (TA), and treated group B (TB).

Unlocking epigenetics for precision treatment of Ewing's sarcoma.

Ewing's sarcoma (EWS) is a highly aggressive malignant bone tumor primarily affecting adolescents and young adults.

Using carbohydrate-based polymers to facilitate testicular regeneration.

Male infertility is a significant global issue affecting 60-80 million people, with 40%-50% of cases linked to male issues. Exposure to radiation, drugs, sickness, the environment, and oxidative stress may result in testicular degeneration. Carbohydrate-based polymers (CBPs) restore testis differentiation and downregulate apoptosis genes.

Multifaceted role of TRIM21 in inflammation.

Tripartite motif (TRIM) family members participate in a variety of cellular activities, such as intracellular signaling, development, cellular death, protein quality control, immunological defense, waste degradation, and the emergence of cancer. These proteins usually act as E3 ubiquitin ligase. The final line of resistance against infectious viruses is a cytosolic ubiquitin ligase and antibody receptor called TRIM containing 21.

Extracellular Vesicles: the Next Frontier in Pregnancy Research.

Extracellular vehicles (EVs) have been involved in several aspects of pregnancy, including endometrial receptivity, embryo implantation, and embryo-maternal communication showing them associated with pregnancy disorders, such as preeclampsia, gestational diabetes mellitus, and preterm birth. Further research is warranted to fully comprehend the exact pathophysiological roles of EVs and to develop new therapies targeting EVs thereby improving pregnancy outcomes. Herein, we review the recent knowledge on the multifaceted roles of EVs during pregnancy and address the majority of the molecular interactions between EVs, maternal, and fetal cells with an emphasis on disorders of pregnancy under the influence of EVs.

Diagnostic and therapeutic value of EVs in lungs diseases and inflammation.

Extracellular vesicles (EVs) are membrane-derived messengers which have been playing an important role in the inflammation and pathogenesis of lung diseases. EVs contain varieties of DNA, RNA, and membrane receptors through which they work as a delivery system for bioactive molecules as well as intracellular communicators. EV signaling mediates tumor progression and metastasis.

Microplastics: unraveling the signaling pathways involved in reproductive health.

Microplastics (MPs) are biologically active environmental pollutants having significant impact on the ecosystem and human health. MPs have been reported to increase oxidative stress, resulting in tissue damage, developmental abnormalities, metabolic disorders, epigenetic changes, abnormal reproduction, and reduced gamete quality. At present, most of the existing literature has focused on the effects of MPs on the reproduction of various aquatic organisms; however, the effects of MPs on mammalian reproduction specifically humans are least studied except a few ones fragmentally discussing the effects of MPs on gametogenesis in human.

Mini-organs with big impact: Organoids in liver cancer studies.

Hepatocellular carcinoma, the most common primary liver cancer and a leading cause of death, is a difficult disease to treat due to its heterogeneous nature. Traditional models, such as 2D culture and patient-derived xenografts, have not proven effective. However, the development of 3D culture techniques, such as organoids, which can mimic the tumor microenvironment (TME) and preserve heterogeneity and pathophysiological properties of tumor cells, offers new opportunities for treatment and research.

From barriers to novel strategies: smarter CAR T therapy hits hard to tumors.

Chimeric antigen receptor (CAR) T cell therapy for solid tumors shows promise, but several hurdles remain. Strategies to overcome barriers such as CAR T therapy-related toxicities (CTT), immunosuppression, and immune checkpoints through research and technology are needed to put the last nail to the coffin and offer hope for previously incurable malignancies. Herein we review current literature and infer novel strategies for the mitigation of CTT while impeding immune suppression, stromal barriers, tumor heterogeneity, on-target/off-tumor toxicities, and better transfection strategies with an emphasis on clinical research and prospects.

Self-assembled and Zn(II)-coordinated dipeptide nanoparticles with membrane-rupturing action on bacteria.

Metal ion-coordinated self-assembled short-chain amino acid peptide molecules with multi-photon excitation wavelengths and their photoluminescence properties are advantageous for fluorescence-based diagnostics and treatments of biological diseases based on their extra features of antibacterial agents. We have designed a novel strategy based on tryptophan molecule coordinated with Zn(II) ions in the form of biocompatible spherical nanoparticles of diameter 30-80 nm which have been used for antibacterial treatments against different kinds of pathogenic bacteria (Escherichia coli, Salmonella typhimurium, and Pseudomonas). Preferably, we have used tryptophan-phenylalanine (Trp-Phe), a dipeptide molecule having tryptophan as principal material against E.

Recent advances to Neuroprotection: repurposing drugs against neuroinflammatory disorders.

Cell death is a natural mechanism for biological clearance for the maintenance of homeostasis in a dynamic microenvironment of the central nervous system. Stress and various factors can lead to imbalance between cellular genesis and cell death leading to dysfunctionality and a number of neuropathological disorders. Drug repurposing can help bypass development time and cost.

Emerging role of lipophagy in liver disorders.

Lipophagy is a selective degradation of lipids by a lysosomal-mediated pathway, and dysregulation of lipophagy is linked with the pathological hallmark of many liver diseases. Downregulation of lipophagy in liver cells results in abnormal accumulation of LDs (Lipid droplets) in hepatocytes which is a characteristic feature of several liver pathologies such as nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). Contrarily, upregulation of lipophagy in activated hepatic stellate cells (HSCs) is associated with hepatic fibrosis and cirrhosis.
