Estimated Burden Of Coccidioidomycosis, Samantha L Williams, Andrej Spec, Et Al.

2020-Current year OA Pubs

IMPORTANCE: Coccidioidomycosis is an underrecognized fungal infection that can cause serious illness and constitutes a considerable public health burden. The number of cases is likely substantially higher than the nationally reported total, as surveillance does not capture patients who do not seek medical care or who are undiagnosed or misdiagnosed. Coccidioidomycosis is not reportable in all states, and cases not reported to public health entities are likewise missed. A systematic estimate of coccidioidomycosis burden is needed to raise awareness and inform public health interventions and policy.

OBJECTIVE: To assess the annual burden of symptomatic coccidioidomycosis in the US.

Age-Related Mesenchymal Stromal Cell Senescence Is Associated With Progression From Mgus To Multiple Myeloma, Natalya Plakhova, Sheila A Stewart, Et Al.

2020-Current year OA Pubs

The risk of progression of monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM) increases with advancing age, suggesting that progression may be influenced by age-related changes within the bone marrow (BM) microenvironment. We hypothesise that senescent mesenchymal stromal cells (MSCs), which accumulate in the BM with age, may contribute to MGUS progression to MM. Here, we show that, like BM MSCs from aged non-cancer controls, BM MSCs from both MM and MGUS patients exhibit a senescent phenotype characterised by enlarged, flattened morphology, increased β-galactosidase activity and CDKN2A expression, and decreased proliferation rate compared with BM MSCs from healthy …

Rna Interference In Protozoan Parasites And Its Application, Lon-Fye Lye, Deborah E Dobson, Stephen M Beverley, Min-Che Tung

2020-Current year OA Pubs

RNA interference (RNAi) is a biological process in which RNA molecules are involved in sequence-specific suppression of gene expression, via small RNA triggers derived from double-stranded RNA that can target specific genes; it is a natural process that plays a role in both the regulation of protein synthesis and in immunity. Discovery of RNAi by Fire and Mello in 1998 had a profound impact on unraveling novel aspects of eukaryotic biology. RNA interference (RNAi) has proven to be an immensely useful tool for studying gene function and validation of potential drug targets in almost all organisms. A great advance in …

Role Of The Ctcf Binding Site In Human T-Cell Leukemia Virus-1 Pathogenesis, Ancy Joseph, Xiaogang Cheng, John Harding, Jacob Al-Saleem, Patrick Green, Malachi Griffith, Deborah Veis, Daniel A. Rauch, Lee Ratner

2020-Current year OA Pubs

During HTLV-1 infection, the virus integrates into the host cell genome as a provirus with a single CCCTC binding protein (CTCF) binding site (vCTCF-BS), which acts as an insulator between transcriptionally active and inactive regions. Previous studies have shown that the vCTCF-BS is important for maintenance of chromatin structure, regulation of viral expression, and DNA and histone methylation. Here, we show that the vCTCF-BS also regulates viral infection and pathogenesis in vivo in a humanized (Hu) mouse model of adult T-cell leukemia/lymphoma. Three cell lines were used to initiate infection of the Hu-mice, i) HTLV-1-WT which carries an intact HTLV-1 …

Large-Scale Network Analysis Of The Cerebrospinal Fluid Proteome Identifies Molecular Signatures Of Frontotemporal Lobar Degeneration, Rowan Saloner, Nupur Ghoshal, Et Al.

2020-Current year OA Pubs

The pathophysiological mechanisms driving disease progression of frontotemporal lobar degeneration (FTLD) and corresponding biomarkers are not fully understood. Here we leveraged aptamer-based proteomics (>4,000 proteins) to identify dysregulated communities of co-expressed cerebrospinal fluid proteins in 116 adults carrying autosomal dominant FTLD mutations (C9orf72, GRN and MAPT) compared with 39 non-carrier controls. Network analysis identified 31 protein co-expression modules. Proteomic signatures of genetic FTLD clinical severity included increased abundance of RNA splicing (particularly in C9orf72 and GRN) and extracellular matrix (particularly in MAPT) modules, as well as decreased abundance of synaptic/neuronal and autophagy modules. The generalizability of genetic FTLD proteomic …

Cysteine Depletion Triggers Adipose Tissue Thermogenesis And Weight Loss, Aileen H Lee, Irina Shchukina, Prabhakar Sairam Andhey, Maxim N Artyomov, Et Al.

2020-Current year OA Pubs

Caloric restriction and methionine restriction-driven enhanced lifespan and healthspan induces 'browning' of white adipose tissue, a metabolic response that increases heat production to defend core body temperature. However, how specific dietary amino acids control adipose thermogenesis is unknown. Here, we identified that weight loss induced by caloric restriction in humans reduces thiol-containing sulfur amino acid cysteine in white adipose tissue. Systemic cysteine depletion in mice causes lethal weight loss with increased fat utilization and browning of adipocytes that is rescued upon restoration of cysteine in diet. Mechanistically, cysteine-restriction-induced adipose browning and weight loss requires sympathetic nervous system-derived noradrenaline signalling via …
