State Key Laboratory of Primate Biomedical Research, Institute of Primate Translational Medicine, Kunming University of Science and Technology, Kunming, China; Yunnan Key Laboratory of Primate Biomedical Research, Kunming, Yunnan, China. Electronic address:

Article Synopsis
  • The study explores how childhood maltreatment (CM) affects brain development in adults, using MRI data from 214 participants.
  • CM seems to result in accelerated brain aging in younger adults, while older adults show signs of delayed brain development compared to those without CM.
  • The findings suggest that types of maltreatment, such as abuse versus neglect, have distinct impacts on neurodevelopment, and CM is linked to increased attentional impulsivity in affected individuals.

January 2025

State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, Sun Yat-Sen University Cancer Center, Guangzhou, Guangdong, China.

Microsatellite stable (MSS) colorectal cancer (CRC) is a subtype of CRC that generally exhibits resistance to immunotherapy, particularly immune checkpoint inhibitors such as PD-1 blockade. This study investigates the effects and underlying mechanisms of combining PD-1 blockade with IDO1 inhibition in MSS CRC. Bioinformatics analyses of TCGA-COAD and TCGA-READ cohorts revealed significantly elevated IDO1 expression in CRC tumors, correlating with tumor mutation burden across TCGA datasets.

Advances in Aggrephagy: Mechanisms, Disease Implications, and Therapeutic Strategies.

J Cell Physiol

January 2025

Guangzhou Municipal and Guangdong Provincial Key Laboratory of Protein Modification and Degradation, School of Basic Medical Sciences, Guangzhou Medical University, Guangzhou, China.

The accumulation of misfolded proteins within cells leads to the formation of protein aggregates that disrupt normal cellular functions and contribute to a range of human pathologies, notably neurodegenerative disorders. Consequently, the investigation into the mechanisms of aggregate formation and their subsequent clearance is of considerable importance for the development of therapeutic strategies. The clearance of protein aggregates is predominantly achieved via the autophagy-lysosomal pathway, a process known as aggrephagy.

In a prospective longitudinal study with 218 Parkinson's disease (PD) patients in the discovery cohort and 84 in the validation cohort, we aimed to identify novel blood biomarkers predicting disability milestones in PD. Through Least Absolute Shrinkage and Selection Operator-Cox (Lasso-Cox) regression, developed nomogram predictive model and Linear mixed-effects models, we identified low level of plasma fibronectin (pFN) as one of the best-performing risk markers in predicting disability milestones. A low level of pFN was associated with a short milestone-free survival period in PD.

January 2025

Cancer Prevention and Treatment Institute of Chengdu, Department of Neurosurgery, Chengdu Fifth People's Hospital (The Second Clinical Medical College, Affiliated Fifth People's Hospital of Chengdu University of Traditional Chinese Medicine), Chengdu 611137, China.

Glioblastoma (GBM), notorious for its poor prognosis, stands as a formidable challenge within the central nervous system tumor category, primarily due to its intricate pathology that encompasses stemness and the epithelial-mesenchymal transition (EMT). The ubiquity of S phase kinase-associated protein 2 (Skp2) overexpression in GBM, a protein implicated in both EMT and stemness traits, correlates with increased drug resistance, elevated tumor grades, and adverse outcomes. This investigation delves into the impact of Raddeanin A (RA), a triterpenoid compound extracted from Anemone raddeana Regel, on GBM, with a special focus on its influence over Skp2 expression levels.
