The inflammatory cytokine tumor necrosis factor modulates the expression of Salmonella typhimurium effector proteins.

Journal of inflammation (London, England)

Ma J, Zhang YG, Xia Y, Sun J.
PMID: 20704730
J Inflamm (Lond). 2010 Aug 12;7:42. doi: 10.1186/1476-9255-7-42.

Tumor necrosis factor alpha (TNF-alpha)is a host inflammatory factor. Bacteria increase TNF-alpha expression in a variety of human diseases including infectious diseases, inflammatory bowel diseases, and cancer. It is unknown, however, how TNF-alpha directly modulates bacterial protein expression during...

Probiotics, nuclear receptor signaling, and anti-inflammatory pathways.

Gastroenterology research and practice

Yoon SS, Sun J.
PMID: 21808643
Gastroenterol Res Pract. 2011;2011:971938. doi: 10.1155/2011/971938. Epub 2011 Jul 26.

There is increased investigation of the human microbiome as it relates to health and disease. Dysbiosis is implicated in various clinical conditions including inflammatory bowel disease (IBD). Probiotics have been explored as a potential treatment for IBD and other...

Enteric bacteria and cancer stem cells.

Cancers

Sun J.
PMID: 21297903
Cancers (Basel). 2010;3(1):285-97. doi: 10.3390/cancers3010285.

Intestinal bacteria can contribute to cell proliferation and cancer development, particularly in chronic infectious diseases in which bacteria and/or bacterial components might interfere with cell function. The number of microbial cells within the gut lumen is estimated to be...

Vitamin D, Vitamin D Receptor, and Tissue Barriers.

Tissue barriers

Zhang YG, Wu S, Sun J.
PMID: 24358453
Tissue Barriers. 2013 Jan 01;1(1). doi: 10.4161/tisb.23118.

Tissue barriers are critical in the pathogenesis of human diseases, such as atopic dermatitis, inflammatory bowel diseases, and various cancers. Preserving or restoring barrier functions of the epithelia cells is a therapeutic strategy to prevent and treat the illness....

Bacterial protein AvrA stabilizes intestinal epithelial tight junctions via blockage of the C-Jun N-terminal kinase pathway.

Tissue barriers

Zhang Y, Wu S, Ma J, Xia Y, Ai X, Sun J.
PMID: 25838979
Tissue Barriers. 2015 Apr 03;3(1):e972849. doi: 10.4161/21688362.2014.972849. eCollection 2015.

The Salmonella type III secretory system secretes virulence proteins, called effectors. Effectors are responsible for the alteration of tight junctions (TJ) and epithelial functions in intestinal infection and inflammation. In a previous study, we have demonstrated that a bacterial...

Leaky intestine and impaired microbiome in an amyotrophic lateral sclerosis mouse model.

Physiological reports

Wu S, Yi J, Zhang YG, Zhou J, Sun J.
PMID: 25847918
Physiol Rep. 2015 Apr;3(4). doi: 10.14814/phy2.12356.

Emerging evidence has demonstrated that intestinal homeostasis and the microbiome play essential roles in neurological diseases, such as Parkinson's disease. Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by a progressive loss of motor neurons and muscle...

Salmonella-infected crypt-derived intestinal organoid culture system for host-bacterial interactions.

Physiological reports

Zhang YG, Wu S, Xia Y, Sun J.
PMID: 25214524
Physiol Rep. 2014 Sep 11;2(9). doi: 10.14814/phy2.12147. Print 2014 Sep 01.

The in vitro analysis of bacterial-epithelial interactions in the intestine has been hampered by a lack of suitable intestinal epithelium culture systems. Here, we report a new experimental model using an organoid culture system to study pathophysiology of bacterial-epithelial...

Suppressed autophagy flux in skeletal muscle of an amyotrophic lateral sclerosis mouse model during disease progression.

Physiological reports

Xiao Y, Ma C, Yi J, Wu S, Luo G, Xu X, Lin PH, Sun J, Zhou J.
PMID: 25602021
Physiol Rep. 2015 Jan 19;3(1). doi: 10.14814/phy2.12271. Print 2015 Jan 01.

Accumulation of abnormal protein inclusions is implicated in motor neuron degeneration in amyotrophic lateral sclerosis (ALS). Autophagy, an intracellular process targeting misfolded proteins and damaged organelles for lysosomal degradation, plays crucial roles in survival and diseased conditions. Efforts were...

Probiotic Lactobacillus rhamnosus GG mono-association suppresses human rotavirus-induced autophagy in the gnotobiotic piglet intestine.

Gut pathogens

Wu S, Yuan L, Zhang Y, Liu F, Li G, Wen K, Kocher J, Yang X, Sun J.
PMID: 23924832
Gut Pathog. 2013 Aug 07;5(1):22. doi: 10.1186/1757-4749-5-22.

BACKGROUND: Human rotavirus (HRV) is the most important cause of severe diarrhea in infants and young children. Probiotic Lactobacillus rhamnosus GG (LGG) reduces rotavirus infection and diarrhea. However, the molecular mechanisms of LGG-mediated protection from rotavirus infection are poorly...

The Vitamin D Receptor, Inflammatory Bowel Diseases, and Colon Cancer.

Current colorectal cancer reports

Lu R, Wu S, Xia Y, Sun J.
PMID: 23814529
Curr Colorectal Cancer Rep. 2012 Mar 01;8(1):57-65. doi: 10.1007/s11888-011-0114-1.

The nuclear receptor is an emerging therapeutic target in various human diseases. Vitamin D receptor (VDR), a nuclear receptor, mediates the biological functions of vitamin D. Classically, vitamin D is recognized as an essential contributor to mineral and bone...
