Research progress and application status of organoid in breast cancer subtypes.

Breast cancer (BC) is a prevalent malignant tumor that poses a significant health risk to women. The complexity of basic BC research and clinical treatment is influenced by multiple factors, including age, fertility, hormone metabolism, molecular subtypes, and tumor grading and staging. Traditional in vitro models often fall short of meeting modern research demands, whereas organoids-an emerging 3D primary culture technology-offer a unique platform that better replicates the tumor microenvironment (TME).

Reprogramming of Treg cell-derived small extracellular vesicles effectively prevents intestinal inflammation from PANoptosis by blocking mitochondrial oxidative stress.

Inflammatory bowel disease (IBD) is a chronic relapsing immune-mediated inflammatory disorder of the alimentary tract without exact etiology. Mitochondrial reactive oxygen species (mtROS) derived from mitochondrial dysfunction impair intestinal barrier function, increase gut permeability, and facilitate immune cell invasion, and, therefore, are considered to have a pivotal role in the pathogenesis of IBD. Here, we reprogrammed regulatory T cell (Treg)-derived exosomes loaded with the antioxidant trace element selenium (Se) and decorated them with the synthetic mitochondria-targeting SS-31 tetrapeptide via a peptide linker.

The Engineering Screen of Photoactive Nanozymes Based on N-Containing Covalent Organic Frameworks for Antibacterial Application.

Nitrogen (N)-heterocycles could effectively improve their photocatalytic activity of COFs. However, the systematic exploration of photoactive nanozymes based on N-containing COFs is still lacking.

Endoscopic transsphenoidal surgery for infradiaphragmatic craniopharyngiomas and impact of diaphragm sellae competence on hypothalamic injury.

Investigate the impact of diaphragm sellae competence on surgical outcomes and risk factors for postoperative hypothalamic injury (HI) in patients undergoing endoscopic transsphenoidal surgery (ETS) for infradiaphragmatic craniopharyngiomas (ICs). A retrospective analysis of 54 consecutive patients (2016-2023) with ICs treated by ETS was conducted. All tumors originated from the sellar region inferior to the diaphragm sellae and were classified into two subtypes in terms of diaphragm sellae competence: IC with competent diaphragm sellae (IC-CDS) and IC with incompetent diaphragm sellae (IC-IDS).

GSDMB interacts with IGF2BP1 to suppress colorectal cancer progression by modulating DUSP6-ERK pathway.

There is growing evidence that the protein family of Gasdermins (GSDMs) play an essential role during the progression of colorectal cancer (CRC). However, it is not completely clear that how GSDMB, abundantly expressed in epithelial cells of gastrointestinal tract, regulates the tumorigenesis of CRC. A wealth of evidence linking GSDMB to the pathogenesis of cancer has come from genome-wide association studies.

4-Octyl itaconate blocks GSDMB-mediated pyroptosis and restricts inflammation by inactivating granzyme A.

GSDMB-mediated pyroptosis facilitates a pro-inflammatory immune microenvironment and needs to be tightly regulated to avoid excessive inflammation. Here, we provide evidence that itaconate and its cell-permeable derivative 4-octyl itaconate (4-OI) can significantly inhibit GSDMB-rendered pyroptotic activity independent of Nrf2. 4-OI interferes proteolytic process of GSDMB by directly modifying Cys54, Cys148 and Ser212 on granzyme A (GrzA), a serine protease that site-specifically cleaves the inter-domain linker of GSDMB, instead of interaction with GSDMB, thereby blocking pyroptosis and exerts anti-inflammatory effects.

Clinical characteristics and treatment strategies for pituitary adenoma associated with intracranial aneurysm.

Background: This study aimed to investigate clinical features and treatment strategies for intracranial aneurysm (IA) associated with pituitary adenoma (PA).
