Novel therapies in Sjögren's disease: A systematic review of the literature.

Sjögren's disease (SjD) is a chronic systemic autoimmune disorder that primarily involves lymphocytic infiltration of exocrine glands, with frequent extra-glandular manifestations. Historically, treatment options for SjD have been limited to alleviating symptoms, rather than treating the underlying cause or preventing disease progression. Furthermore, past clinical trials of therapies such as rituximab failed to demonstrate improvement in symptoms or disease activity.

Neuron-targeted caveolin-1 overexpression attenuates cognitive loss and pathological transcriptome changes in symptomatic Alzheimer's disease models.

Alzheimer's disease (AD) is a devastating neurodegenerative disorder characterized by progressive synaptic loss and cognitive decline. Gene therapy that augments intrinsic neuroprotective pathways offers a promising strategy to mitigate neurodegeneration and prevent further cognitive loss. Caveolin-1 (Cav-1), a membrane lipid raft (MLR) scaffolding protein, regulates multiple pro-growth and pro-survival signaling pathways within plasmalemmal microdomains.

Diabetic neuropathy: cutting-edge research and future directions.

Diabetic neuropathy (DN) is a prevalent and debilitating complication of diabetes mellitus, significantly impacting patient quality of life and contributing to morbidity and mortality. Affecting approximately 50% of patients with diabetes, DN is predominantly characterized by distal symmetric polyneuropathy, leading to sensory loss, pain, and motor dysfunction, often resulting in diabetic foot ulcers and lower-limb amputations. The pathogenesis of DN is multifaceted, involving hyperglycemia, dyslipidemia, oxidative stress, mitochondrial dysfunction, and inflammation, which collectively damage peripheral nerves.

Intravenous Magnesium and Cisplatin-Associated Acute Kidney Injury.

Importance: Cisplatin-associated acute kidney injury (CP-AKI) is a frequent complication of cisplatin chemotherapy and is associated with considerable morbidity and mortality. Prophylactic administration of intravenous (IV) magnesium attenuates CP-AKI in animal models; however, its association with CP-AKI in humans has not been rigorously evaluated.

Objective: To evaluate the association of prophylactic IV magnesium administration with CP-AKI in patients with cancer undergoing cisplatin chemotherapy.

Overcoming extracellular vesicle-mediated fratricide improves CAR T cell treatment against solid tumors.

The efficacy of chimeric antigen receptor (CAR) T cells against solid tumors is limited. The molecular mechanisms underlying CAR T cell resistance are yet to be elucidated and new strategies need to be developed to improve treatment outcomes. Here we report that solid tumors respond to CAR T cells by upregulating the secretion of small extracellular vesicles carrying tumor antigens, which are horizontally transferred to CAR T cells, leading to antigen recognition and CAR T cell fratricide.

Nonoperative Management of Technically Resectable Pancreatic Cancer With Ablative Radiation Therapy.

Importance: Surgical resection of pancreatic ductal adenocarcinoma (PDAC) modestly improves long-term survival due to the competing risk of metastatic disease. However, postoperative morbidity often interferes with administration of systemic therapy and may be unacceptable to some patients. Ablative radiation therapy (A-RT) has emerged as an effective noninvasive local treatment in many tumor types and may provide an alternative to surgery in select patients with resectable PDAC.

Immune Cell Engagers: Advancing Precision Immunotherapy for Cancer Treatment.

Immune cell engagers (ICEs) are an emerging class of immunotherapies designed to harness the immune system's anti-tumor potential through precise targeting and activation of immune effector cells. By engaging T cells, natural killer (NK) cells, and phagocytes, ICEs overcome challenges such as immune evasion and MHC downregulation, addressing critical barriers in cancer treatment. T-cell engagers (TCEs), led by bispecific T-cell engagers (BiTEs), dominate the field, with innovations such as half-life-extended BiTEs, trispecific antibodies, and checkpoint inhibitory T-cell engagers driving their application in hematologic and solid malignancies.

Glibenclamide targets MDH2 to relieve aging phenotypes through metabolism-regulated epigenetic modification.

Mitochondrial metabolism-regulated epigenetic modification is a driving force of aging and a promising target for therapeutic intervention. Mitochondrial malate dehydrogenase (MDH2), an enzyme in the TCA cycle, was identified as an anti-aging target through activity-based protein profiling in present study. The expression level of MDH2 was positively correlated with the cellular senescence in Mdh2 knockdown or overexpression fibroblasts.

Epigenetics-targeted drugs: current paradigms and future challenges.

Epigenetics governs a chromatin state regulatory system through five key mechanisms: DNA modification, histone modification, RNA modification, chromatin remodeling, and non-coding RNA regulation. These mechanisms and their associated enzymes convey genetic information independently of DNA base sequences, playing essential roles in organismal development and homeostasis. Conversely, disruptions in epigenetic landscapes critically influence the pathogenesis of various human diseases.

Two distinct epithelial-to-mesenchymal transition programs control invasion and inflammation in segregated tumor cell populations.

Epithelial-to-mesenchymal transition (EMT) triggers cell plasticity in embryonic development, adult injured tissues and cancer. Combining the analysis of EMT in cell lines, embryonic neural crest and mouse models of renal fibrosis and breast cancer, we find that there is not a cancer-specific EMT program. Instead, cancer cells dedifferentiate and bifurcate into two distinct and segregated cellular trajectories after activating either embryonic-like or adult-like EMTs to drive dissemination or inflammation, respectively.

Iron homeostasis and ferroptosis in human diseases: mechanisms and therapeutic prospects.

Iron, an essential mineral in the body, is involved in numerous physiological processes, making the maintenance of iron homeostasis crucial for overall health. Both iron overload and deficiency can cause various disorders and human diseases. Ferroptosis, a form of cell death dependent on iron, is characterized by the extensive peroxidation of lipids.

Glucagon-like peptide-1 receptor: mechanisms and advances in therapy.

The glucagon-like peptide-1 (GLP-1) receptor, known as GLP-1R, is a vital component of the G protein-coupled receptor (GPCR) family and is found primarily on the surfaces of various cell types within the human body. This receptor specifically interacts with GLP-1, a key hormone that plays an integral role in regulating blood glucose levels, lipid metabolism, and several other crucial biological functions. In recent years, GLP-1 medications have become a focal point in the medical community due to their innovative treatment mechanisms, significant therapeutic efficacy, and broad development prospects.

Hyperuricemia and its related diseases: mechanisms and advances in therapy.

Hyperuricemia, characterized by elevated levels of serum uric acid (SUA), is linked to a spectrum of commodities such as gout, cardiovascular diseases, renal disorders, metabolic syndrome, and diabetes, etc. Significantly impairing the quality of life for those affected, the prevalence of hyperuricemia is an upward trend globally, especially in most developed countries. UA possesses a multifaceted role, such as antioxidant, pro-oxidative, pro-inflammatory, nitric oxide modulating, anti-aging, and immune effects, which are significant in both physiological and pathological contexts.

Feeding gut microbes to nourish the brain: unravelling the diet-microbiota-gut-brain axis.

The prevalence of brain disorders, including stress-related neuropsychiatric disorders and conditions with cognitive dysfunction, is rising. Poor dietary habits contribute substantially to this accelerating trend. Conversely, healthy dietary intake supports mood and cognitive performance.

Aspirin Use and Incidence of Colorectal Cancer According to Lifestyle Risk.

Importance: Aspirin reduces the risk of colorectal cancer (CRC). Identifying individuals more likely to benefit from regular aspirin use for CRC prevention is a high priority.

Objective: To assess whether aspirin use is associated with the risk of CRC across different lifestyle risk factors.

A 160 Gbp fork fern genome shatters size record for eukaryotes.

Vascular plants are exceptional among eukaryotes due to their outstanding genome size diversity which ranges ∼2,400-fold, including the largest genome so far recorded in the angiosperm (148.89 Gbp/1C). Despite available data showing that giant genomes are restricted across the Tree of Life, the biological limits to genome size expansion remain to be established.

Tumor evolution metrics predict recurrence beyond 10 years in locally advanced prostate cancer.
