2020-Current year OA Pubs

OBJECTIVE: Adipose tissue mass is maintained by a balance between lipolysis and lipid storage. The contribution of adipose tissue lipogenesis to fat mass, especially in the setting of high-fat feeding, is considered minor. Here we investigated the effect of adipose-specific inactivation of the peroxisomal lipid synthetic protein PexRAP on fatty acid synthase (FASN)-mediated lipogenesis and its impact on adiposity and metabolic homeostasis.

METHODS: To explore the role of PexRAP in adipose tissue, we metabolically phenotyped mice with adipose-specific knockout of PexRAP. Bulk RNA sequencing was used to determine transcriptomic responses to PexRAP deletion and

RESULTS: Adipose-specific PexRAP deletion promoted diet-induced …

A Protective Role For Type I Interferon Signaling Following Infection With Mycobacterium Tuberculosis Carrying The Rifampicin Drug Resistance-Conferring Rpob Mutation H445y, Suhas Bobba, Kuldeep S. Chauhan, Sadia Akter, Shibali Das, Ekansh Mittal, Barun Mathema, Jennifer A. Philips, Shabaana A. Khader

2020-Current year OA Pubs

Interleukin-1 (IL-1) signaling is essential for controlling virulent Mycobacterium tuberculosis (Mtb) infection since antagonism of this pathway leads to exacerbated pathology and increased susceptibility. In contrast, the triggering of type I interferon (IFN) signaling is associated with the progression of tuberculosis (TB) disease and linked with negative regulation of IL-1 signaling. However, mice lacking IL-1 signaling can control Mtb infection if infected with an Mtb strain carrying the rifampin-resistance conferring mutation H445Y in its RNA polymerase β subunit (rpoB-H445Y Mtb). The mechanisms that govern protection in the absence of IL-1 signaling during rpoB-H445Y Mtb infection are unknown. In this study, …

Neighborhood Disadvantage And Breast Cancer-Specific Survival In The Us, Neha Goel, Alexandra E Hernandez, Angela Mazul

2020-Current year OA Pubs

IMPORTANCE: Despite improvements in breast cancer screening, treatment, and survival, disparate breast cancer-specific survival outcomes persist, particularly in disadvantaged neighborhoods. Most of these disparities are attributed to disparities in individual, tumor, and treatment characteristics. However, a critical knowledge gap exists as to whether disparities in breast cancer-specific survival remain after accounting for individual, tumor, and treatment characteristics.

OBJECTIVE: To evaluate if neighborhood disadvantage is associated with shorter breast cancer-specific survival after controlling for individual, tumor, and treatment characteristics in a national population.

DESIGN, SETTING, AND PARTICIPANTS: This national retrospective cohort study included patients with breast cancer diagnosed from 2013 to …

Pyridoxine Challenge Reflects Pediatric Hypophosphatasia Severity And Thereby Examines Tissue-Nonspecific Alkaline Phosphatase's Role In Vitamin B6 Metabolism, Michael P Whyte, Fan Zhang, Karen E Mack, Deborah Wenkert, Gary S Gottesman, Karen L Ericson, Jeffrey T Cole, Stephen P Coburn

2020-Current year OA Pubs

Alkaline phosphatase (ALP) is detected in most human tissues. However, ALP activity is routinely assayed using high concentrations of artificial colorimetric substrates in phosphate-free laboratory buffers at lethal pH. Hypophosphatasia (HPP) is the inborn-error-of-metabolism caused by loss-of-function mutation(s) of the ALPL gene that encodes the ALP isoenzyme expressed in bone, liver, kidney, and elsewhere and is therefore designated "tissue-nonspecific" ALP (TNSALP). Consequently, HPP harbors clues concerning the biological function of this phosphohydrolase that is anchored onto the surface of cells. The biochemical signature of HPP features low serum ALP activity (hypophosphatasemia) together with elevated plasma levels of three natural substrates …

The WHO Model List of Essential Medicines (EML) prioritizes medicines that have significant global public health value. The EML can also deliver important messages on appropriate medicine use. Since 2017, in response to the growing challenge of antimicrobial resistance, antibiotics on the EML have been reviewed and categorized into three groups: Access, Watch, and Reserve, leading to a new categorization called AWaRe. These categories were developed taking into account the impact of different antibiotics and classes on antimicrobial resistance and the implications for their appropriate use. The 2023 AWaRe classification provides empirical guidance on 41 essential antibiotics for over 30 …

Dna Combing Versus Dna Spreading And The Separation Of Sister Chromatids, Alice Meroni, Sophie E Wells, Carmen Fonseca, Arnab Ray Chaudhuri, Keith W Caldecott, Alessandro Vindigni

2020-Current year OA Pubs

DNA combing and DNA spreading are two central approaches for studying DNA replication fork dynamics genome-wide at single-molecule resolution by distributing labeled genomic DNA on coverslips or slides for immunodetection. Perturbations in DNA replication fork dynamics can differentially affect either leading or lagging strand synthesis, for example, in instances where replication is blocked by a lesion or obstacle on only one of the two strands. Thus, we sought to investigate whether the DNA combing and/or spreading approaches are suitable for resolving adjacent sister chromatids during DNA replication, thereby enabling the detection of DNA replication dynamics within individual nascent strands. To …

A Targeted Proteomics Method For Quantifying Plasma Apolipoprotein Kinetics In Individual Mice Using Stable Isotope Labeling, Baohai Shao, Masami Shimizu-Albergine, Farah Kramer, Jenny E Kanter, Jay W Heinecke, Tomas Vaisar, Bettina Mittendorfer, Bruce W Patterson, Karin E Bornfeldt

2020-Current year OA Pubs

Altered apolipoprotein kinetics play a critical role in promoting dyslipidemia and atherogenesis. Human apolipoprotein kinetics have been extensively evaluated, but similar studies in mice are hampered by the lack of robust methods suitable for the small amounts of blood that can be collected at sequential time points from individual mice. We describe a targeted liquid chromatography tandem mass spectrometry method for simultaneously quantifying the stable isotope enrichment of several apolipoproteins represented by multiple peptides in serial blood samples (15 μl each) obtained after retro-orbital injection of

T-Cell Acute Lymphoblastic Leukemia/Lymphoma (T-All) With Negative Screening Immaturity Markers And Gamma-Delta Receptor Expression, Maria Faraz, Anita Parmigiani, Nina Monkash, Anne Chen

2020-Current year OA Pubs

T-cell acute lymphoblastic leukemia/lymphoma (T-ALL) is characterized by the combination of T-cell lineage and the presence of immaturity marker(s). Sometimes, the most common immaturity markers for initial flow cytometry screening in T-ALL may be negative, which can be a diagnostic pitfall. When a lack of common first-line immaturity markers is encountered in combination with gamma/delta T-cell receptor expression, a misdiagnosis of mature gamma-delta T-cell leukemia/lymphoma could be rendered. Here, we discuss two T-ALL cases with the absence of common flow cytometry immaturity markers and positive gamma/delta receptor expression.

The elderly demographic is the fastest-growing segment of the world's population and is projected to exceed 1.5 billion people by 2050. With multimorbidity, polypharmacy, susceptibility to drug-drug interactions, and frailty as distinct risk factors, elderly patients are especially vulnerable to developing potentially life-threatening safety events such as serious forms of drug-induced liver injury (DILI). It has been a longstanding shortcoming that elderly individuals are often a vulnerable population underrepresented in clinical trials. As such, an improved understanding of DILI in the elderly is a high-priority, unmet need. This challenge is underscored by recent documents put forward by the U.S. Food …

Exploring The Association Between Weight Loss-Inducing Medications And Multiple Sclerosis: Insights From The Fda Adverse Event Reporting System Database, Afsaneh Shirani, Anne H Cross, Olaf Stuve

2020-Current year OA Pubs

BACKGROUND: Several studies have demonstrated that early childhood and adolescent obesity are risk factors for multiple sclerosis (MS) susceptibility. Obesity is thought to share inflammatory components with MS through overproduction of pro-inflammatory adipokines (e.g., leptin) and reduction of anti-inflammatory adipokines (e.g, adiponectin). Recently, drug repurposing (i.e. identifying new indications for existing drugs) has garnered significant attention. The US Food and Drug Administration Adverse Event Reporting System (FAERS) database serves not only as a resource for mining adverse drug reactions and safety signals but also for identifying inverse associations and potential medication repurposing opportunities.
