As an enzyme with a critical role in de novo purine synthesis, adenylosuccinate lyase (ADSL) expression is upregulated in various malignancies. However, whether ADSL possesses noncanonical functions that contribute to cancer progression remains poorly understood. Here, we demonstrate that protein kinase R-like endoplasmic reticulum kinase (PERK) activated by lipid deprivation or ER stress phosphorylates ADSL at S140, leading to an enhanced association between ADSL and Beclin1.

Nucleoside analogs (NAs), as antiviral drugs, play a significant role in clinical medicine, constituting approximately 50 % of all antiviral therapies in current use. Nucleoside inhibitors function by mimicking the structure of natural nucleosides, integrating themselves into viral genetic material during replication, and subsequently inhibiting the virus's ability to reproduce. They are used to treat a variety of viral infections, including herpes simplex, hepatitis B, and acquired immunodeficiency syndrome (AIDS).

Background: Resistance to chemoimmunotherapy in patients with advanced non-small cell lung cancer (NSCLC) necessitates effective prognostic biomarkers. Although F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) has shown potential for efficacy assessment, it has been mainly evaluated in immuno-monotherapy setting, lacking elaborations in the scenarios of immunotherapy combined with chemotherapy. To tackle this dilemma, we aimed to build a non-invasive PET/CT-based model for stratifying tumor heterogeneity and predicting survival in advanced NSCLC patients undergoing chemoimmunotherapy.

-Methyl-d-aspartate (NMDA) receptors, a subtype of ionotropic glutamate receptors in the central nervous system (CNS), have garnered attention for their role in brain disorders. Specifically, GluN2A-containing NMDA receptors have emerged as a potential therapeutic target for the treatment of depressive disorders and epilepsy. However, the development of GluN2A-containing NMDA receptor-selective antagonists, represented by -(4-(2-benzoylhydrazine-1-carbonyl)benzyl)-3-chloro-4-fluorobenzenesulfonamide (TCN-201) and its derivatives, faces a significant challenge due to their limited ability to penetrate the blood-brain barrier (BBB), hampering their characterization and further advancement.

Article Synopsis
  • Osteoarthritis (OA) is the most prevalent degenerative joint disease globally, particularly affecting the elderly and lacking effective early treatments due to limited understanding of its causes.
  • Interleukin-1 (IL-1β) is a key inflammatory mediator in early OA that harms chondrocytes and cartilage, emphasizing the need for targeted therapies.
  • This study explores the potential of echinatin, a health supplement with known anti-inflammatory properties, demonstrating its ability to inhibit chondrocyte activity through the NF-kB signaling pathway, offering promising new treatment options for OA.

Background: Trichophyton rubrum is a widespread human pathogenic fungus, colonizing keratinized tissue of outer body-parts. Thereby, the pathogen is relying on nutrients available from the host. The invasive mechanism of the pathogen is relaying on secreted proteases, which hydrolyze skin-proteins for subsequent up-take.

Inspired by our previous finding that targeting the 150-cavity with a multisite-binding strategy emerged as an effective approach to obtain more potent and selective neuraminidase (NA) inhibitors against influenza virus, we present here the design, synthesis, and optimization of novel boron-containing N-substituted oseltamivir (OSC) derivatives. Exploratory structure-activity relationship (SAR) studies led to the identification of compounds and as the most potent NA inhibitors, surpassing OSC in potency against both wild-type group-1 NAs and oseltamivir-resistant NAs. These compounds demonstrated significant antiviral activity against several wild-type strains and H1N1pdm09 strains (EC = 0.

Introduction: Defects in the DNA mismatch repair (MMR) pathway can predispose individuals to colorectal cancer (CRC), with germline mutations in this pathway leading to Lynch syndrome. Consequently, universal MMR testing is recommended for all newly diagnosed CRC patients to detect mismatch repair deficient (MMR-D) tumors, enabling informed treatment decisions. Given the increased potential for metachronous disease in patients with Lynch syndrome, the current guidelines for surgical management of Lynch-associated colon cancer recommend extended resection in patients under age 60.

Mitochondrial dysfunction is a key event driving the maladaptive repair of tubular epithelial cells during the transition from acute kidney injury to chronic kidney disease (CKD). Therefore, identifying potential targets involved in mitochondrial dysfunction in tubular epithelial cells is clinically important. Myeloid-derived growth factor (MYDGF), a novel secreted protein, plays important roles in multiple cardiovascular diseases, but the function of MYDGF in tubular epithelial cells remains unknown.

Papillary thyroid carcinoma (PTC) is generally considered a highly indolent endocrine malignancy, often accompanied by cervical lymph node metastasis and rarely involving distant metastases. We present a rare case of a 37-year-old woman with PTC, who exhibited regional lymph node metastasis, right breast metastasis, and probable right psoas major and multiple bone metastases. Initial symptoms included hoarseness, and subsequent examination revealed a secondary malignant tumor in the right breast, originating from the thyroid gland.
