Background: Malaria, characterised by inflammation and multi-organ complications, needs novel chemotherapeutics due to the rise of drug-resistant malaria parasites, which is a serious health issue. Naringin (NGN), a flavanone glycoside (naringenin 7-O-neohesperidose), has a broad spectrum of pharmacological activities but its effect against malaria, alone and in combination, was not deeply investigated.

Purpose: To assess the pharmacological efficacy of NGN alone and in combination with chloroquine (CQ) against a Plasmodium strain resistant to CQ and to elucidate its potential mode of action.

CCAAT/enhancer-binding protein α (C/EBPα), a key myeloid transcription factor, drives myeloid differentiation from blast cells by regulating the expression of granulocyte colony stimulating factor receptor and C/EBPε as required for promoting granulocyte differentiation. Here, we show that serine/threonine-protein kinase NLK, also known as Nemo-like kinase, physically associates with C/EBPα and phosphorylates it at multiple sites, including Ser21, Thr226, Thr230 and S234, leading to its ubiquitin-mediated degradation. Individual phospho-point mutants of C/EBPα could be phosphorylated by NLK, but a mutant with all phosphorylatable residues replaced by alanine resisted phosphorylation and degradation by NLK, as did the single point mutants.

The escalating severity of the menace posed by bacterial resistance has rendered the existing antibiotics less effective, thus necessitating the discovery of new antibacterial agents. The current study reports the exploration of substituted N-pyridinylaminonaphthols produced by a straightforward, one-pot multicomponent reaction process as antibacterial agents. The synthesized derivatives were assessed in vitro for their antibacterial properties against a panel of bacterial pathogens.

Article Synopsis
  • The review talks about how liver problems (like cirrhosis) can lead to a type of diabetes called hepatogenous diabetes (HD).
  • It shows how the body’s use of insulin and sugar is messed up in both cirrhosis and type II diabetes, hinting that they may have similar causes.
  • Finally, it stresses the importance of figuring out and treating these issues in patients with liver cirrhosis to help them stay healthy.

The Duffy antigen receptor is a seven-transmembrane (7TM) protein expressed primarily at the surface of red blood cells and displays strikingly promiscuous binding to multiple inflammatory and homeostatic chemokines. It serves as the basis of the Duffy blood group system in humans and also acts as the primary attachment site for malarial parasite Plasmodium vivax and pore-forming toxins secreted by Staphylococcus aureus. Here, we comprehensively profile transducer coupling of this receptor, discover potential non-canonical signaling pathways, and determine the cryoelectron microscopy (cryo-EM) structure in complex with the chemokine CCL7.

Introduction: The sodium-glucose co-transporter 2 (SGLT2) inhibitors are FDA-approved class of drugs for diabetes management. They improve glycemic control by inducing glucosuria. Notwithstanding with potent anti-hyperglycemic activity, SGLT2 inhibitors are emerging as drugs with multifaceted therapeutic potential, evidenced for cardioprotective, renoprotective, antihypertensive, and neuroprotective activities.

Division of Endocrinology and Centre for Research in Anabolic Skeletal Targets in Health and Illness (ASTHI), CSIR-Central Drug Research Institute, Sector 10, Jankipuram Extension, Sitapur Road, Lucknow, 226031, India.

Article Synopsis
  • Adiponectin is a protein that helps control how our bodies use sugar and fat, and there's a special piece of it called ADP-1 that can help build bones better than the whole protein.
  • Researchers found that ADP-1 helps bone cells called osteoblasts grow and work by using two different methods, one involving energy production and the other involving a signaling pathway important for bone health.
  • In tests on rats with weak bones, ADP-1 improved bone strength and structure by encouraging new bone formation and stopping the breakdown of old bone, which could help people with osteoporosis.

The construction of biologically interesting -heterocycles under metal-free conditions is a constant goal in industry and academia. Herein, we have developed an hexafluoroisopropanol (HFIP)-mediated intramolecular cyclization of allenamides, providing tetrahydro-β-carboline derivatives embedded with a C1-vinyl functionality. The metal-free protocol provided tetrahydro-β-carboline derivatives atom-efficiently under room temperature with a broad substrate scope in good to excellent yields.

Background: Spermatogenesis is a temperature-sensitive process, and elevation in temperature hampers this process quickly and significantly. We studied the molecular effects of testicular heating on piRNAs and gene expression in rat testicular germ cells.

Methods: We generated a cryptorchid rat model by displacing the testis from the scrotal sac (34 °C) to the abdominal area (37 °C) and sacrificed animals after 1 day, 3 days, and 5 days.

Background: Glioblastoma (GBM) is the most aggressive among the tumors of the central nervous system (CNS), and has a dismal prognosis. Altered metabolism, especially the increased rate of aerobic glycolysis promotes rapid proliferation of GBM cells. Here, we investigated the role of aldehyde dehydrogenase 5 family member A1 (ALDH5A1), a mitochondrial enzyme in the aspect of GBM metabolism.

sporozoites invade hepatocytes, transform into liver stages, and replicate into thousands of merozoites that infect erythrocytes and cause malaria. Proteins secreted from micronemes play an essential role in hepatocyte invasion, and unneeded micronemes are subsequently discarded for replication. The liver-stage parasites are potent immunogens that prevent malarial infection.

Organoid technology, revolutionizing biomedical research, offers a transformative approach to studying human developmental biology, disease pathology, and drug discovery. Originating from the pioneering work of Henry Van Peters Wilson in 1907 and evolving through subsequent breakthroughs, organoids are three-dimensional structures derived from stem cells or tissue explants that mimic the architecture and function of organs . With the ability to model various organs such as intestine, liver, brain, kidney, and more, organoids provide unprecedented insights into organ development, disease mechanisms, and drug responses.

  • Runx2 is super important for making bones, and without it, baby animals can't grow bones and die after birth.
  • We found a protein called Hakai that helps Runx2 work better and is also linked to bone health.
  • When we increased Hakai in lab tests, it helped cells turn into bone-making cells, but if we changed Hakai to a non-working form, it didn't help at all.

Hypertension-induced brain renin-angiotensin system (RAS) activation and neuroinflammation are hallmark neuropathological features of neurodegenerative diseases. Previous studies from our lab have shown that inhibition of ACE/Ang II/AT1R axis (by AT1R blockers or ACE inhibitors) reduced neuroinflammation and accompanied neurodegeneration via up-regulating adult hippocampal neurogenesis. Apart from this conventional axis, another axis of RAS also exists i.

Breast cancer is a heterogeneous disease, with a subpopulation of tumor cells known as breast cancer stem cells (BCSCs) with self-renewal and differentiation abilities that play a critical role in tumor initiation, progression, and therapy resistance. The tumor microenvironment (TME) is a complex area where diverse cancer cells reside creating a highly interactive environment with secreted factors, and the extracellular matrix. Autophagy, a cellular self-digestion process, influences dynamic cellular processes in the tumor TME integrating diverse signals that regulate tumor development and heterogeneity.
