Elevated Histone Lactylation Mediates Ferroptosis Resistance in Endometriosis Through the METTL3‐Regulated HIF1A/HMOX1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study reveals that histone lactylation, a modification derived from lactate, plays a crucial role in ferroptosis resistance in ectopic endometrial stromal cells. This resistance is mediated via the HIF1A/HMOX1 pathway regulated by METTL3. In vivo, a combination of 2‐DG and erastin shows promise as an effective treatment for endometriosis ...

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Effect of leisure time physical activity on severe knee or hip osteoarthritis leading to total joint replacement: a population-based prospective cohort study

open access: yesBMC Musculoskeletal Disorders, 2012
Background Studies on leisure time physical activity as risk factor or protective factor for knee or hip osteoarthritis (OA) show divergent results. Longitudinal prospective studies are needed to clarify the association of physical activity with future ...

H3K36me3‐Guided m6A Modification of Oncogenic L1CAM‐AS1 Drives Macrophage Polarization and Immunotherapy Resistance in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
L1CAM‐AS1 is identified as a novel H3K36me3‐guided, m6A‐modified long noncoding RNA (lncRNA) in hepatocellular carcinoma (HCC) cells. L1CAM‐AS1 stabilizes RAN protein, enhances M2 macrophages‐released CCL5‐induced nuclear import of RELA, activates the NF‐κB signaling, up‐regulates CCL2 expression and secretion from HCC cells, and enhances M2 ...

Acetabular “up-and-in” defect treated with in-situ femoral head autograft technique during total hip arthroplasty

open access: yesArthroplasty Today, 2019
A 56-year-old male laborer with severe superior and medial acetabular protusio was treated with a cementless left total hip arthroplasty (THA) using an inexpensive technique that preserved the incarcerated femoral head in situ.

Exosomes From Intestinal Epithelial Cells Promote Hepatic Differentiation of Liver Progenitor Cells in Gut‐Liver‐on‐a‐Chip Models

open access: yesAdvanced Science, EarlyView.
The effects of intestinal epithelial cells and their exosomes on the hepatic differentiation of HPCs are explored in a gut‐liver‐on‐a‐chip. Exosomes from intestinal epithelial cells improve liver fibrosis. Moreover, the miR‐371‐373 cluster in the exosomes may mediate this effect by regulating the hepatic differentiation of HPCs.

Single‐Cell and Spatial Transcriptomic Profiling of Penile Squamous Cell Carcinoma Reveals Dynamics of Tumor Differentiation and Immune Microenvironment

open access: yesAdvanced Science, EarlyView.
This study uses single‐nucleus RNA sequencing and spatial transcriptomics to investigate penile squamous cell carcinoma (PSCC). It reveals that PSCC tumor cells mimic normal penile epithelium differentiation, independent of HPV status. The Tum_1 subtype shows basal stem‐like characteristics and promotes invasiveness. HPV‐positive basal stem‐like tumors

ACSS2‐Mediated Histone H4 Lysine 12 Crotonylation (H4K12cr) Alleviates Colitis via Enhancing Transcription of CLDN7

open access: yesAdvanced Science, EarlyView.
Histone lysine crotonylation (Kcr) is a highly conserved posttranslational modification implicated with crucial biological processes. This study reveals that ACSS2‐mediated H4K12cr upregulated CLDN7 transcription to strengthen intestinal epithelial barrier.
