Counterbalancing O‐GlcNAcylation and STAT3 Phosphorylation in Ventral Tegmental Area Dopaminergic Neurons Mediates Behavioral Adaptations to Acute Restraint Stress

open access: yesAdvanced Science, EarlyView.
Acute restraint stress enhances STAT3Ser727 phosphorylation in dopaminergic neurons in mice. This modification promotes the upregulation of GABBR2 and GABRB3, reduces neuronal activity, and contributes to anxiety‐like behavior and diminished reward‐seeking following stress exposure.

HIGD1A Alleviates Oxidative Stress Related Ovarian Hypofunction by Enhancing Granulosa Cell Functions via NF‐κB/SOD2 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
HIGD1A maintains redox homeostasis in granulosa cells by modulating SOD2‐mediated dismutation of superoxide into H2O2, which is cleared by CAT and GPX enzymes. However, reduced HIGD1A activates the NF‐κB pathway and upregulates SOD2, leading to intracellular H2O2 accumulation due to impaired clearance.

GHSR‐Foxo1 Signaling in Macrophages Promotes Liver Fibrosis via Inflammatory Response and Hepatic Stellate Cell Activation

open access: yesAdvanced Science, EarlyView.
Macrophage GHSR‐Foxo1 axis regulates CCl4‐induced liver fibrosis by promoting inflammation and TGF‐β1‐mediated HSC activation. GHSR activates PKA‐dependent phosphorylation of Foxo1 at serine 273, promoting macrophage pro‐inflammatory polarization to enhance the production of pro‐inflammatory cytokines that damage hepatocytes, thereby inducing liver ...

The effect of endoscopic transsphenoidal somatotroph tumors resection on pituitary hormones: systematic review and meta-analysis

open access: yesWorld Journal of Surgical Oncology, 2023
Purpose Currently, endoscopic transsphenoidal surgery is the main treatment for pituitary neuroendocrine tumors (PitNETs). Excision of the tumor may have positive or negative effects on pituitary endocrine function, and the pituitary function of ...

Alternative Models for Anticancer Drug Discovery From Natural Products Using Binary Tumor‐Microenvironment‐on‐a‐Chip

open access: yesAdvanced Science, EarlyView.
This study presents a binary tumor‐microenvironment‐on‐a‐chip (T‐MOC) system incorporating multicellular tumor spheroids (MCTs) as an alternative preclinical platform to evaluate the efficacy of anticancer natural products. The T‐MOC model reproduces in vivo drug delivery barriers and physiological conditions, enabling morphological analysis to predict

Metabolic profiling reveals distinct metabolic alterations in different subtypes of pituitary adenomas and confers therapeutic targets

open access: yesJournal of Translational Medicine, 2019
Background Pituitary adenomas are common brain tumors. Although transsphenoidal surgery are able to achieve extensive tumor removal, the rate of recurrence ranges from 5 to 20% depending on the different subtype.

Target delineation and optimal radiosurgical dose for pituitary tumors

open access: yesRadiation Oncology, 2016
Stereotactic radiosurgery (SRS) delivered as either single-fraction or multi-fraction SRS (2–5 fractions) is frequently employed in patients with residual or recurrent pituitary adenoma. The most common delivery systems used for SRS include the cobalt-60

Impact of Ghrelin‐Depleting Gastrectomy on Long‐Term Endocrine and Metabolic Health With a Focus on Skeletal Muscle and Bone Mineral Content

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This study investigates the long‐term endocrine and metabolic consequences of ghrelin‐depleted gastrectomy, with a focus on skeletal muscle mass and bone mineral content. Sustained reductions in serum desacyl‐ghrelin were linked to lower IGF‐1 levels, resulting in significant loss of muscle and bone.

A Hybrid Transfer Learning Framework for Brain Tumor Diagnosis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel hybrid transfer learning approach for brain tumor classification achieves 99.47% accuracy using magnetic resonance imaging (MRI) images. By combining image preprocessing, ensemble deep learning, and explainable artificial intelligence (XAI) techniques like gradient‐weighted class activation mapping and SHapley Additive exPlanations (SHAP), the ...
