Cellular FLICE-like inhibitory protein (cFLIP) critically maintains apoptotic resistance in human lens epithelial cells.

Cell Death Dis 2021 Apr 9;12(4):386. Epub 2021 Apr 9.

Department of Cellular Biology and Anatomy, Medical College of Georgia at Augusta University, Augusta, GA, USA.

The present study aims to understand the mechanism of the lens epithelial cell's strong anti-apoptotic capacity and survival in the mature human lens that, on the one hand, maintains lens transparency over several decades, while on the other hand, increases the risk of posterior capsule opacification (PCO). Here we compared FHL124 cells and HeLa cells, spontaneously immortalized epithelial cell lines derived from the human lens and cervical cancer cells, respectively, of their resistance to TNFα-mediated cell death. TNFα plus cycloheximide (CHX) triggered almost all of HeLa cell death. Read More

Levels of Zinc Transporters mRNA Depending on Zinc Status and HIV-1 Tat Induced Inflammation in Muscle (Rhabdomyosarcoma) and Monocyte (THP-1) Cell Lines.

Biochemistry (Mosc) 2021 Feb;86(2):168-178

Molecular Biology Division, ICMR-National Institute of Nutrition, Hyderabad, 500007, India.

Monocytes and muscles demonstrate functionally contrasting behavior under conditions of zinc deficiency with relation to zinc storage system (muscle retain zinc in contrast to monocytes). We aimed to understand the effects of zinc status and HIV-1 Tat mediated inflammation on expression of zinc transporters in these types of cells. Expression of zinc transporters [ZnTs, ZIPs, and metallothionein (MT)] was quantified by qRT-PCR in RD, THP-1 cells separately and in co-cultured THP-1-RD cells. Read More

Persistent bone resorption lacunae on necrotic bone distinguish bisphosphonate-related osteonecrosis of jaw from denosumab-related osteonecrosis.

J Bone Miner Metab 2021 Apr 8. Epub 2021 Apr 8.

Tokyo Dental College Research Branding Project, 2-9-18 Kanda-Misaki-cho, Chiyoda-ku, Tokyo, 101-0061, Japan.

Background: Bisphosphonate and denosumab are widely used for the treatment of osteoporosis and bone metastasis of cancer to prevent excessive bone resorption. Osteonecrosis of the jaw is a serious adverse effect of bisphosphonate or denosumab referred to as bisphosphonate-related osteonecrosis of the jaw (BRONJ) or denosumab-related osteonecrosis of the jaw (DRONJ), respectively. Since bisphosphonate and denosumab inhibit bone resorption by different mechanism, we evaluated whether these drug types result in different histopathological characteristics related to bone resorption.

Sepsis in cougar (Puma concolor) associated with Chromobacterium violaceum.

Braz J Microbiol 2021 Apr 7. Epub 2021 Apr 7.

Laboratory of Microbiology and Molecular Biology, Veterinary Hospital from UFMT, Cuiabá, Brazil.

The genus Chromobacterium is widely distributed in the environment and is composed of Gram-negative, aerobic, or facultative anaerobic bacilli that occur in violet-colored colonies. These bacteria rarely cause infections, but when it occurs, it spreads quickly and has a high mortality. Because diseases are infrequent, the diagnosis is often delayed, and it takes time for suitable treatment to be initiated, leading to increased mortality due to the rapid progression of the disease.

Spoligotype-specific risk of finding lesions in tissues from cattle infected by Mycobacterium bovis.

BMC Vet Res 2021 Apr 7;17(1):148. Epub 2021 Apr 7.

VISAVET Health Surveillance Centre, Universidad Complutense de Madrid, Madrid, Spain.

Background: Although the pathogenic effect of members of the Mycobacterium tuberculosis complex in susceptible hosts is well known, differences in clinical signs and pathological findings observed in infected animals have been reported, likely due to a combination of host and pathogen-related factors. Here, we investigated whether Mycobacterium bovis strains belonging to different spoligotypes were associated with a higher risk of occurrence of visible/more severe lesions in target organs (lungs and/or lymph nodes) from infected animals. A large collection of 8889 samples belonging to cattle were classified depending on the presence/absence of tuberculosis-like lesions and its degree of severity. Read More

Interaction of amphiphilic lipoarabinomannan with host carrier lipoproteins in tuberculosis patients: Implications for blood-based diagnostics.

PLoS One 2021 7;16(4):e0243337. Epub 2021 Apr 7.

Physical Chemistry and Applied Spectroscopy, Chemistry Division, Los Alamos National Laboratory, Los Alamos, New Mexico, United States of America.

Lipoarabinomannan (LAM), an amphiphilic lipoglycan of the Mycobacterium tuberculosis cell wall, is a diagnostic target for tuberculosis. Previous work from our laboratory and others suggests that LAM is associated with host serum lipoproteins, which may in turn have implications for diagnostic assays. Our team has developed two serum assays for amphiphile detection: lipoprotein capture and membrane insertion. Read More

Targeting stanniocalcin-1-expressing tumor cells elicits efficient antitumor effects in a mouse model of human lung cancer.

Cancer Med 2021 Apr 7. Epub 2021 Apr 7.

Department of Thoracic Surgery, Institute of Development, Aging and Cancer, Tohoku University, Sendai, Japan.

Lung cancer is the most common cause of cancer-related death in developed countries; therefore, the generation of effective targeted therapeutic regimens is essential. Recently, gene therapy approaches toward malignant cells have emerged as attractive molecular therapeutics. Previous studies have indicated that stanniocalcin-1 (STC-1), a hormone involved in calcium and phosphate homeostasis, positively regulates proliferation, apoptosis resistance, and glucose metabolism in lung cancer cell lines.

Mitochondrial Pyruvate Carrier Subunits Are Essential for Pyruvate-Driven Respiration, Infectivity, and Intracellular Replication of Trypanosoma cruzi.

mBio 2021 04 6;12(2). Epub 2021 Apr 6.

Center for Tropical and Emerging Global Diseases and Department of Cellular Biology, University of Georgia, Athens, Georgia, USA

Pyruvate is the final metabolite of glycolysis and can be converted into acetyl coenzyme A (acetyl-CoA) in mitochondria, where it is used as the substrate for the tricarboxylic acid cycle. Pyruvate availability in mitochondria depends on its active transport through the heterocomplex formed by the mitochondrial pyruvate carriers 1 and 2 (MPC1/MPC2). We report here studies on MPC1/MPC2 of , the etiologic agent of Chagas disease. Read More

Department of Laboratory Animal Medicine, Research Institute for Veterinary Science, BK21 PLUS Program for Creative Veterinary Science Research, College of Veterinary Medicine, Seoul National University, Seoul 08826, Republic of Korea.

Environmental pollution (EP) is a well-known threat to wild animals, but its toxicological impact is poorly understood. In vitro toxicity evaluation using cells of lower predators could be a promising way to assess and monitor the effects of EPs on whole wildlife populations that are related in the food web. Here, we describe EPs' toxic effect and mechanism in the primary fibroblast derived from the embryo of the striped field mouse, Apodemus agrarius. Read More

Podocalyxin is a key negative regulator of human endometrial epithelial receptivity for embryo implantation.

Hum Reprod 2021 Apr 2. Epub 2021 Apr 2.

Centre for Reproductive Health, Hudson Institute of Medical Research, Clayton, VIC, Australia.

Study Question: How is endometrial epithelial receptivity, particularly adhesiveness, regulated at the luminal epithelial surface for embryo implantation in the human?

Summary Answer: Podocalyxin (PCX), a transmembrane protein, was identified as a key negative regulator of endometrial epithelial receptivity; specific downregulation of PCX in the luminal epithelium in the mid-secretory phase, likely mediated by progesterone, may act as a critical step in converting endometrial surface from a non-receptive to an implantation-permitting state.

What Is Known Already: The human endometrium must undergo major molecular and cellular changes to transform from a non-receptive to a receptive state to accommodate embryo implantation. However, the fundamental mechanisms governing receptivity, particularly at the luminal surface where the embryo first interacts with, are not well understood. Read More

Department of General and Visceral Surgery, Medical Center and Faculty of Medicine, University of Freiburg, Hugstetter Str. 55, 79106, Freiburg, Germany.

Pancreatic ductal adenocarcinoma (PDAC) is a disease with a very unfavorable prognosis. Surgical resection represents the only potentially curative treatment option, but recurrence after complete resection is almost certain. In an exploratory attempt we here aimed at identifying preoperative plasma protein biomarkers with the potential to predict early recurrence after resection of PDAC. Read More
