Steroid Receptor Coactivator‐1 Drives Tumor‐Associated Macrophage Reprogramming by Mediating MMP12 Transcription in Pancreatic Cancer Perineural Invasion

open access: yesAdvanced Science, EarlyView.
Steroid receptor coactivator‐1 (SRC‐1) reprograms tumor‐associated macrophages (TAMs) via signal transducer and activator of transcription 1(STAT1)‐mediated matrix metallopeptidase 12 (MMP12) transcription to drive perineural invasion (PNI) in pancreatic cancer.

Structural Studies of Calmodulin Activation of Estrogen Receptor Alpha [PDF]

open access: yesBiophysical Journal, 2011
The goal is to determine the mechanism of calcium-dependent activation of estrogen receptor alpha (ERa) by calmodulin (CaM) and to ascertain how oxidative stress and oxidative modifications mediate the interactions between CaM, ERa and antiestrogens.

Lifespan‐Regulated CAR‐Macrophages from Myeloid Progenitors for Enhanced Colorectal Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Using a tamoxifen‐inducible Hoxb8 system, proliferative bone marrow progenitors can be generated, which are subsequently engineered with an anti‐CEA CAR construct containing a suicide gene (iCas9) and differentiated into CAR‐macrophages. This method facilitates scale up the production of CAR‐macrophages.

Pigment Epithelium‐Derived Factor Deficiency Impairs Hippocampal Glutamate Homeostasis and Cognitive Function by Downregulating Astrocytic GLT‐1

open access: yesAdvanced Science, EarlyView.
The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

Integrative Omics Reveals Glutamine Catabolism‐Driven Apoptotic Suppression in Monocytes upon Mechanical Unloading

open access: yesAdvanced Science, EarlyView.
This research integrated multi‐omics analysis of bone tissue from HLU and control mice revealed that mechanical unloading suppresses intrinsic apoptosis and augments glutamine (Gln) catabolism in osteoclast lineage cells. The findings highlight pivotal roles for SLC1A5‐mediated Gln metabolism and XIAP/Diablo axis‐mediated apoptosis suppression.

Effects of Inhibiting the Proteasomal Degradation of Estrogen Receptor .ALPHA. on Estrogen Receptor .ALPHA. Activation under Hypoxic Conditions

open access: yesBiological and Pharmaceutical Bulletin, 2009
Hypoxia, which is intimately associated with the biology of breast carcinomas, modulates the level of estrogen receptor (ER) alpha expression and transactivation. We investigated the effect of blocking ER degradation on ERalpha-mediated transactivation under hypoxic conditions using the proteasome inhibitor MG132.

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

open access: yesAdvanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

Life Factors and Melanoma: From the Macroscopic State to the Molecular Mechanism

open access: yesAdvanced Science, EarlyView.
Melanoma, an aggressive skin cancer, arises from dynamic interactions between genetic, environmental, and lifestyle factors. This review explores how age, gender, obesity, diet, exercise, smoking, alcohol, UV exposure, circadian rhythms, and medications influence melanoma risk and progression.

The effects of female sexual steroids on gastric function and barrier resistance of gastrointestinal tract following traumatic brain injury

open access: yesJournal of Pharmacy and Bioallied Sciences, 2015
Aim: The aim was to assess the alteration of gastric function and barrier function of gastrointestinal (GI) tract following diffuse brain injury in varying ovarian hormone status. Materials and Methods: Diffuse traumatic brain injury (TBI) was induced by
