Integrated Transcriptomics Reveals Evolutionary Trajectories and Cell Density‐Dependent Mechanisms in Aldosterone‐Producing Adenomas

open access: yesAdvanced Science, EarlyView.
Aldosterone‐producing adenomas (APAs) develop via two distinct paths: directly from adrenal zona glomerulosa (zG) cells, or stepwise from zG cells through aldosterone‐producing micronodules (APMs) before progressing to APAs. Advanced single‐cell and spatial analyses identified distinct cell states linked to oxidative stress and cell–cell interactions ...

Relationship Between Gastric Helicobacter pylori Infection and Colorectal Polyps: A Retrospective Cohort Study [PDF]

open access: yesIranian Journal of Colorectal Research
Background: Infection with Helicobacter pylori (H. pylori) infection is one of the most prevalent bacterialinfections worldwide. It is well-established as a contributing factor to various conditions, including chronicgastritis, peptic ulcers, and gastric

Gemella morbillorum Promotes Colorectal Carcinogenesis: LPBDCP‐Mediated Invasion Activates Ras Signaling and Destabilizes p53

open access: yesAdvanced Science, EarlyView.
ABSTRACT Gut microbiota dysbiosis promotes colorectal cancer (CRC) tumorigenesis. A global fecal metagenomic analysis identified Gemella morbillorum as a key contributor to the CRC‐associated microbiota. Fluorescence in situ hybridization revealed that Gemella morbillorum is enriched in CRC tumor tissues compared to adjacent normal tissues.

Characterization of Human Pituitary Adenomas in Cell Cultures by Light And Electron Microscopic Morphology And Immunolabeling [PDF]

open access: yes, 2005
The morphology and hormone production of pituitary adenoma cell cultures were compared in order to highlight their characteristic in vitro features. Cell suspensions were prepared from 494 surgical specimens.

A novel methodology for in vivo endoscopic phenotyping of colorectal cancer based on real-time analysis of the mucosal lipidome: a prospective observational study of the iKnife [PDF]

open access: yes, 2016
Background: This pilot study assessed the diagnostic accuracy of rapid evaporative ionization mass spectrometry (REIMS) in colorectal cancer (CRC) and colonic adenomas. Methods: Patients undergoing elective surgical resection for CRC were recruited at St.

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome

open access: yesAdvanced Science, EarlyView.
By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

AIP and MEN1 mutations and AIP immunohistochemistry in pituitary adenomas in a tertiary referral center. [PDF]

open access: yes, 2019
Background: Pituitary adenomas have a high disease burden due to tumor growth/ invasion and disordered hormonal secretion. Germline mutations in genes such as MEN1 and AIP are associated with early onset of aggressive pituitary adenomas that can be ...

A Soft Matrix Microenvironment Promotes Laterally Spreading Tumors via Oxidative Phosphorylation‐Dependent Cell Adhesion

open access: yesAdvanced Science, EarlyView.
Laterally spreading tumors (LSTs) are precancerous colorectal lesions characterized by a flat morphology. This study reveals a mechanochemical pathway through which a soft matrix microenvironment diminishes spatial constraints in intestinal adenomas. This process promotes deficiencies in tight junction proteins, mediated by the mechanoreceptor ADORA2B ...

Gastrointestinal Manifestations in Rubinstein‐Taybi Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Rubinstein–Taybi syndrome is a rare genetic condition associated with a wide range of physical, cognitive, and developmental impairments, yet its gastrointestinal manifestations remain poorly characterized. Case reports and small series suggest a high prevalence of gastroesophageal reflux, constipation, dysphagia, and nutritional compromise ...
