Genetic and pharmacological inhibition of fatty acid-binding protein 4 alleviated inflammation and early fibrosis after toxin induced kidney injury.

Int Immunopharmacol 2021 May 12;96:107760. Epub 2021 May 12.

Kidney Research Institute, Division of Nephrology, West China Hospital of Sichuan University, Chengdu 610041, China.

Considerable data have suggested that acute kidney injury (AKI) is often incompletely repaired and could lead to chronic kidney disease (CKD). As we known, toxin-induced nephropathy triggers the rapid production of proinflammatory mediators and the prolonged inflammation allows the injured kidneys to develop interstitial fibrosis. In our previous study, fatty acid-binding protein 4 (Fabp4) has been reported to be involved in the process of AKI. Read More

Department of Biotechnology, University of Kashmir, Srinagar 190006, J&K, India. Electronic address:

β-Glucans are polysaccharides generally obtained from the cell wall of bacteria, fungi, yeasts, and aleurone layer of cereals. β-Glucans are polymers, with β-1,3 glucose as core linear structure, but they differ in their main branch length, linkages, and branching patterns, giving rise to high and low-molecular-weight β-glucans. They are well-known cell response modifiers with immune-modulating, nutraceutical, and health beneficial effects, including anticancer and pro-apoptotic properties. Read More

Cancer stem cell marker DCLK1 reprograms small extracellular vesicles toward migratory phenotype in gastric cancer cells.

Proteomics 2021 May 15:e2000098. Epub 2021 May 15.

Cancer Inflammation Laboratory, Olivia Newton-John Cancer Research Institute, Heidelberg, VIC, Australia.

Doublecortin-like kinase 1 (DCLK1) is a putative cancer stem cell marker, a promising diagnostic and prognostic maker for malignant tumors and a proposed driver gene for gastric cancer (GC). DCLK1 overexpression in a majority of solid cancers correlates with lymph node metastases, advanced disease and overall poor-prognosis. In cancer cells, DCLK1 expression has been shown to promote epithelial-to-mesenchymal transition (EMT), driving disruption of cell-cell adhesion, cell migration and invasion. Read More

PP1, PKA and DARPP-32 in breast cancer: A retrospective assessment of protein and mRNA expression.

J Cell Mol Med 2021 May 15. Epub 2021 May 15.

Division of Cancer and Stem Cells, Nottingham Breast Cancer Research Centre, School of Medicine, University of Nottingham Biodiscovery Institute, Nottingham, UK.

Cyclic AMP-dependent protein kinase A (PKA) and protein phosphatase 1 (PP1) are proteins involved in numerous essential signalling pathways that modulate physiological and pathological functions. Both PP1 and PKA can be inhibited by dopamine- and cAMP-regulated phosphoprotein 32 kD (DARPP-32). Using immunohistochemistry, PKA and PP1 expression was determined in a large primary breast tumour cohort to evaluate associations between clinical outcome and clinicopathological criteria (n > 1100).

Dual activity of anthocyanidin reductase supports the dominant plant proanthocyanidin extension unit pathway.

Sci Adv 2021 May 14;7(20). Epub 2021 May 14.

BioDiscovery Institute and Department of Biological Sciences, University of North Texas, Denton, TX 76203, USA.

Proanthocyanidins (PAs) are plant natural products important for agriculture and human health. They are polymers of flavan-3-ol subunits, commonly (-)-epicatechin and/or (+)-catechin, but the source of the in planta extension unit that comprises the bulk of the polymer remains unclear, as does how PA composition is determined in different plant species. Anthocyanidin reductase (ANR) can generate 2,3--epicatechin as a PA starter unit from cyanidin, which itself arises from 2,3--leucocyanidin, but ANR proteins from different species produce mixtures of flavan-3-ols with different stereochemistries in vitro.

Propionate production from carbon monoxide by synthetic co-cultures of spp. and propionigenic bacteria.

Appl Environ Microbiol 2021 May 14. Epub 2021 May 14.

Laboratory of Microbiology, Wageningen University & Research, Stippeneng 4, 6708 WE Wageningen, The Netherlands

Gas fermentation is a promising way for converting CO-rich gases to chemicals. We studied the use of synthetic co-cultures composed of carboxydotrophic and propionigenic bacteria to convert CO to propionate. So far isolated carboxydotrophs cannot directly ferment CO to propionate, and therefore this co-cultivation approach was investigated. Read More

Zinc limitation triggers anticipatory adaptations in Mycobacterium tuberculosis.

PLoS Pathog 2021 May 14;17(5):e1009570. Epub 2021 May 14.

School of Life Sciences, University of Hawai'i at Mānoa, Honolulu, Hawaii, United States of America.

Mycobacterium tuberculosis (Mtb) has complex and dynamic interactions with the human host, and subpopulations of Mtb that emerge during infection can influence disease outcomes. This study implicates zinc ion (Zn2+) availability as a likely driver of bacterial phenotypic heterogeneity in vivo. Zn2+ sequestration is part of "nutritional immunity", where the immune system limits micronutrients to control pathogen growth, but this defense mechanism seems to be ineffective in controlling Mtb infection.

Synthesis of a biotinylated heptose 1,7-bisphosphate analogue, a probe to study immunity and inflammation.

Org Biomol Chem 2021 May 14. Epub 2021 May 14.

University of Namur (UNamur), NARILIS, Department of Chemistry, rue de Bruxelles 61, 5000 Namur, Belgium.

d-glycero-d-manno-Heptose-1β,7-bisphosphate (HBP) is a bacterial metabolite that can induce a TIFA-dependent innate immune response in mammals. It was recently discovered that after HBP enters into the cytoplasm of the host cell, it is transformed into ADP-heptose-7-phosphate, which then leads to ALPK1-TIFA-dependent inflammatory response. In order to provide a molecular tool allowing the discovery of the proteins involved in this novel inflammatory pathway, we designed and synthesized a biotinylated analogue of HBP. Read More

Mapping of the amniotic fluid proteome of fetuses with congenital anomalies of the kidney and urinary tract identifies Plastin 3 as a protein involved in glomerular integrity.

J Pathol 2021 May 13. Epub 2021 May 13.

Institut National de la Santé et de la Recherche Médicale (INSERM), U1297, Institut of Cardiovascular and Metabolic Disease, Toulouse, France.

Congenital anomalies of the kidney and the urinary tract (CAKUT) are the first cause of chronic kidney disease in childhood. Several genetic and environmental origins are associated with CAKUT, but most pathogenic pathways remain elusive. Considering the amniotic fluid (AF) composition as a proxy for fetal kidney development, we analyzed the AF proteome from non-severe CAKUT (n=19), severe CAKUT (n=14), and healthy control (n=22) fetuses using LC-MS/MS.

Center of Deep Sea Research and Key Laboratory of Marine Ecology & Environmental Sciences (CODR and KLMEES), Institute of Oceanology, Chinese Academy of Sciences, Qingdao, China.

Symbiosis with chemosynthetic bacteria is an important ecological strategy for the deep-sea megafaunas including mollusks, tubeworms and crustacean to obtain nutrients in hydrothermal vents and cold seeps. How the megafaunas recognize symbionts and establish the symbiosis has attracted much attention. Bathymodiolinae mussels are endemic species in both hydrothermal vents and cold seeps while the immune recognition mechanism underlying the symbiosis is not well understood due to the nonculturable symbionts.

Exp Ther Med 2021 Jul 29;22(1):689. Epub 2021 Apr 29.

Department of Pediatric Allergy and Immunology, Celal Bayar University Medical Faculty, Manisa 45030, Turkey.

Besides maintaining a physical barrier with adherens junctional (AJ) and tight junctional proteins, airway epithelial cells have important roles in modulating the inflammatory processes of allergic asthma. E-cadherin and β-catenin are the key AJ proteins that are involved in airway remodeling. Various mediators such as transforming growth factor-β (TGF-β), epidermal growth factor (EGF), fibroblast growth factor (FGF), platelet derived growth factor (PDGF), insulin-like growth factor (IGF), tumor necrosis factor-α (TNF-α) and angiogenic factors, such as vascular endothelial growth factor (VEGF), are released by the airway epithelium in allergic asthma.
