Comparative analysis of clinical characteristics of symptomatic pituitary adenomas in elderly patients: a consecutive series of 114 patients.

Background: Pituitary adenomas (PAs) present with clinical features such as neuroendocrine abnormalities and mass effects, common in the general morbidity population. However, in elderly patients, the disease progression renders some clinical features difficult to detect and identify in time. Consequently, elderly patients with PAs are often not identified and receive sufficient intervention on time to achieve a satisfactory outcome.

Split-design approach enhances the therapeutic efficacy of ligand-based CAR-T cells against multiple B-cell malignancies.

To address immune escape, multi-specific CAR-T-cell strategies use natural ligands that specifically bind multiple receptors on malignant cells. In this context, we propose a split CAR design comprising a universal receptor expressed on T cells and ligand-based switch molecules, which preserves the natural trimeric structure of ligands like APRIL and BAFF. Following optimization of the hinges and switch labeling sites, the split-design CAR-T cells ensure the native conformation of ligands, facilitating the optimal formation of immune synapses between target cancer cells and CAR-T cells.

Chinese expert consensus on allergen component resolved diagnosis.

Background: Allergen component resolved diagnosis (CRD) is a method for identifying specific protein molecules that cause hypersensitivity. Unlike traditional methods that use crude allergen extracts containing multiple component species, CRD focuses on individual allergen protein molecules for more precise diagnosis. The World Allergy Organization (WAO) recommends CRD as a supplement to clinical history and allergen extract testing, and in some cases, it can replace crude extract tests.

TRIM33 promotes glycolysis through regulating P53 K48-linked ubiquitination to promote esophageal squamous cell carcinoma growth.

Esophageal squamous cell carcinoma (ESCC) is a common fatal malignant tumor of the digestive tract; however, its pathogenic mechanism is unknown and lacks specific molecular diagnosis and treatment. Therefore, it is particularly important to identify new tumor biomarkers to enhance the early diagnosis and molecular-targeted therapy of ESCC. Here, we found that the E3 ubiquitin ligase Tripartitemotif-containing33 (TRIM33) is highly expressed in ESCC tissues and cell lines, and is associated with adverse clinical outcomes.

Unravelling oncosis: morphological and molecular insights into a unique cell death pathway.

Programmed cell death (PCD) is a fundamental biological process for maintaining cellular equilibrium and regulating development, health, and disease across all living organisms. Among the various types of PCD, apoptosis plays a pivotal role in numerous diseases, notably cancer. Cancer cells frequently develop mechanisms to evade apoptosis, increasing resistance to standard chemotherapy treatments.

Alendronate sodium induces G1 phase arrest and apoptosis in human umbilical vein endothelial cells by inhibiting ROS-mediated ERK1/2 signaling.

Bisphosphonates are potent bone resorption inhibitors, among which alendronate sodium (ALN) is commonly prescribed for most osteoporosis patients, but long-term application of ALN can cause bisphosphonate-related osteonecrosis of jaw (BRONJ), the pathogenesis of which remains unclear. Previous studies have suggested that bisphosphonates cause jaw ischemia by affecting the biological behavior of vascular endothelial cells, leading to BRONJ. However, the impacts of ALN on vascular endothelial cells and its mechanism remain unclear.

Multi-omic validation of the cuproptosis-sphingolipid metabolism network: modulating the immune landscape in osteosarcoma.

Background: The current understanding of the mechanisms by which metal ion metabolism promotes the progression and drug resistance of osteosarcoma remains incomplete.

Pharmacological Activities of and Its Derivative-"Chrysoeriol" in Skin Diseases.

Unlabelled: Chrysoeriol is an active ingredient derived from the Chinese medicinal herb (CMH) "" in the dried flower bud or bloomed flower of Thunberg. Dermatoses are the most common diseases in humans, including eczema, acne, psoriasis, moles, and fungal infections, which are temporary or permanent and may be painless or painful. Topical corticosteroids are widely used in Western medicine, but there are some side effects when it is continuously and regularly utilized in a large dosage.

Higher TIGIT+ γδ T cells may predict poor prognosis in younger adult patients with non-acute promyelocytic AML.

Introduction: γδ T cells recognize and exert cytotoxicity against tumor cells. They are also considered potential immune cells for immunotherapy. Our previous study revealed that the altered expression of immune checkpoint T-cell immunoreceptor with immunoglobulin and ITIM domain (TIGIT) on γδ T cells may result in immunosuppression and is possibly associated with a poor overall survival in acute myeloid leukemia (AML).

Phosphoglycerate Kinase 1: An Effective Therapeutic Target in Cancer.

Phosphoglycerate kinase 1 (PGK1) serves as a pivotal enzyme in the cellular glycolysis pathway, facilitating adenosine-triphosphate (ATP) production in tumor cells and driving the Warburg effect. PGK1 generates ATP through the reversible phosphorylation reaction of 1,3-bisphosphoglycerate (1,3-BPG) to Mg-adenosine-5'-diphosphate (Mg-ADP). In addition to its role in regulating cellular metabolism, PGK1 plays a pivotal role in autophagy induction, regulation of the tricarboxylic acid cycle (TCA), and various mechanisms including tumor cell drug resistance, and so on.
