Article Synopsis
  • - Influenza vaccination is linked to lower rates of cardiovascular issues and overall mortality, but the role of related immunoglobulins isn't fully understood.
  • - A specific immunoglobulin heavy chain junction sequence (SD6) was found to inhibit plasma kallikrein activity, potentially reducing thromboinflammatory responses and stroke damage.
  • - In tests on mice, SD6 decreased thrombosis and cerebral injury without increasing bleeding risk, indicating its promise as a treatment for conditions related to blood inflammation.

TOTEM: a multi-cancer detection and localization approach using circulating tumor DNA methylation markers.

BMC Cancer

July 2024

Department of Colorectal and Anal Surgery/Hubei Key Laboratory of Intestinal and Colorectal Diseases, Zhongnan Hospital of Wuhan University, Wuhan, 430071, China.

Background: Detection of cancer and identification of tumor origin at an early stage improve the survival and prognosis of patients. Herein, we proposed a plasma cfDNA-based approach called TOTEM to detect and trace the cancer signal origin (CSO) through methylation markers.

Methods: We performed enzymatic conversion-based targeted methylation sequencing on plasma cfDNA samples collected from a clinical cohort of 500 healthy controls and 733 cancer patients with seven types of cancer (breast, colorectum, esophagus, stomach, liver, lung, and pancreas) and randomly divided these samples into a training cohort and a testing cohort.

HSP70 protects against acute pancreatitis-elicited intestinal barrier damage in rats.

Clin Res Hepatol Gastroenterol

August 2024

Department of Gastroenterology, The Affiliated Yan'An Hospital of Kunming Medical University, Kunming 650051, Yunnan, People's Republic of China. Electronic address:

Acute pancreatitis (AP) is a frequent but severe abdominal emergency in general surgery with intestinal barrier dysfunction. Heat shock protein 70 (HSP70) is a ubiquitous molecular chaperone that has been proposed to exert favorable effects on AP. Nonetheless, the detailed impacts of HSP70 on the intestinal barrier function in AP are unknown, which will be investigated here.

FNDC5 inhibits autophagy of bone marrow mesenchymal stem cells and promotes their survival after transplantation by downregulating Sp1.

Department of Neurology, The First Affiliated Hospital, Sun Yat-sen University; Guangdong Provincial Key Laboratory of Diagnosis and Treatment of Major Neurological Diseases, National Key Clinical Department and Key Discipline of Neurology, Guangzhou, China.

Regenerative therapy based on mesenchymal stem cells (MSCs) has great promise to achieve functional recovery in cerebral infarction patients. However, the survival rate of transplanted MSCs is extremely low because of destructive autophagy caused by the harsh ischemic microenvironment in cerebral infarct tissue. The mechanism by which fibronectin type III domain protein 5 (FNDC5) regulates autophagy of transplanted bone marrow-MSCs (BMSCs) following ischemic injury needs to be elucidated.

Background: Acute pancreatitis (AP) is a disease featuring acute inflammation of the pancreas and histological destruction of acinar cells. Approximately 20% of AP patients progress to moderately severe or severe pancreatitis, with a case fatality rate of up to 30%. However, a single indicator that can serve as the gold standard for prognostic prediction has not been discovered.

Alzheimer's disease (AD) is neurodegenerative disease common in the elderly, whose pathological mechanism is the deposition of amyloid-β (Aβ) plaques and neurofibrillary tangles in the brain. Pyroptosis is a programmed cell death mediated by Gasdermin protein. After the activation of inflammasomes, the cleaved caspase⁃ 1/4/5/11 activates GSDMD, which promotes the release of inflammatory substances and eventually causes cell swelling and death.

Parkinson's disease (PD) is a common neurodegenerative disease in middle-aged and elderly people, and there is less research on the relationship between immunity and PD. In this study, the protein-protein interaction networks (PPI) data, 2747 human immune-related genes (HIRGs), 2078 PD-related genes (PDRGs), and PD-related datasets (GSE49036 and GSE20292) were downloaded from the Human Protein Reference Database (HPRD), Amigo 2, DisGeNET, and Gene Expression Omnibus (GEO) databases, respectively. An immune- or PD-directed neighbor co-expressed network construction (IOPDNC) was drawn based on the GSE49036 dataset and HPRD database.

Kidney Disease Center, The First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou, PR China; National Key Clinical Department of Kidney Diseases, PR China; Institute of Nephropathy, Zhejiang University, Hangzhou, PR China; Zhejiang Dialysis Quality Control Center, PR China. Electronic address:

Article Synopsis
  • Long-term exposure to particulate air pollutants is known to increase mortality in hemodialysis patients, but little research has focused on the effects of short-term exposure.
  • A comprehensive study analyzed data from over 18,000 hemodialysis patient deaths across multiple hospitals and cities to investigate the relationship between short-term particulate matter exposure and mortality rates.
  • The results indicated that even a slight increase in particulate matter levels significantly raises daily mortality rates among hemodialysis patients, underscoring the need for improved air quality policies to protect vulnerable populations.

FNDC5 overexpression promotes the survival rate of bone marrow mesenchymal stem cells after transplantation in a rat cerebral infarction model.

Ann Transl Med

January 2022

Department of Neurology, The First Affiliated Hospital, Sun Yat-sen University, Guangdong Provincial Key Laboratory of Diagnosis and Treatment of Major Neurological Diseases, National Key Clinical Department and Key Discipline of Neurology, Guangzhou, China.

Background: Most bone marrow mesenchymal stem cell (BMSC) death is caused by the harsh ischemia and hypoxic microenvironment, which impacts the therapeutic effects of transplanted BMSCs. Fibronectin type III domain-containing protein 5 (FNDC5) and its cleaved product, irisin, are reportedly involved in cerebral protective effect. Research into whether FNDC5 plays a key role in the survival rate of BMSCs and cerebral infarction (CI) remains inadequate.

Toll-like receptor 2 and 4 (TLR2, TLR4) signaling is implicated in atherosclerotic plaque formation. The two-stage master regulator Virtual Inference of Protein-activity by Enriched Regulon (VIPER) analysis of macrophage TLR2 and TLR4 signature genes integrated with coexpression network genes derived from 371 patient-derived carotid specimens identifies activated RNA polymerase II transcriptional coactivator p15 (SUB1/Sub1, PC4) as a master regulon in the atherogenic TLR response. It is found that TLR2 and TLR4 signaling is proinflammatory and proatherosclerotic in chow-fed apolipoprotein E-deficient (ApoE ) mice.

Rituximab is a chimeric monoclonal antibody directed against the CD20 expressed on B cells, originally used to treat lymphoma but is increasingly used for the treatment of autoimmune diseases. Membranous nephropathy is an autoimmune disease resulting from the deposition of IgG and complements components onto the subepithelial layer of the glomerular capillary wall and remains the leading cause of nephrotic syndrome in adults. Several prospective and retrospective studies showed rituximab induces remission and may decrease proteinuria in patients with membranous nephropathy.
