Effects of intestine-specific deletion of FGF15 on the development of fatty liver disease with vertical sleeve gastrectomy.

Background: Vertical sleeve gastrectomy (SGx) is a type of bariatric surgery to treat morbid obesity and metabolic dysfunction-associated steatotic liver disease (MASLD). The molecular mechanisms of SGx to improve MASLD are unclear, but increased bile acids (BAs) and FGF19 (mouse FGF15) were observed. FGF15/19 is expressed in the ileum in response to BAs and is critical in not only suppressing BA synthesis in the liver but also promoting energy expenditure.

The presence of retraction clefts correlates with lymphovascular invasion and lymph node metastasis and predicts poor outcome: Analysis of 2497 breast cancer patients.

Some invasive breast carcinomas are surrounded by a clear space that separate the tumor cells from the adjacent stroma, similar to invasive micropapillary carcinoma (IMPC), but lack the thin strands of connective tissue that separate the cells and characteristic "inside-out" growth pattern of IMPC on immunohistochemical stain for EMA. We consider the presence of the retraction clefts a common phenomenon that may present as a precursor stage of IMPC (PSIMPC). In this study, a total of 2497 cases of invasive breast carcinomas were prospectively collected.

Exploring Pharmacological Functions of Alternatively Spliced Variants of the Mu Opioid Receptor Gene, , via Gene-Targeted Animal Models.

The mu opioid receptor has a distinct place in the opioid receptor family, since it mediates the actions of most opioids used clinically (e.g., morphine and fentanyl), as well as drugs of abuse (e.

Alternative Pre-mRNA Splicing of the Mu Opioid Receptor Gene, : Insight into Complex Mu Opioid Actions.

Most opioid analgesics used clinically, including morphine and fentanyl, as well as the recreational drug heroin, act primarily through the mu opioid receptor, a class A Rhodopsin-like G protein-coupled receptor (GPCR). The single-copy mu opioid receptor gene, , undergoes extensive alternative splicing, creating multiple splice variants or isoforms via a variety of alternative splicing events. These splice variants can be categorized into three major types based on the receptor structure: (1) full-length 7 transmembrane (TM) C-terminal variants; (2) truncated 6TM variants; and (3) single TM variants.

Real-World Observational Review of Andexanet Alfa Prescribing and Utilization Outcomes at a Community Teaching Hospital.

Objectives: Andexanet alfa is the first approved antidote in the management of life-threatening bleeds in patients treated with Xa inhibitors. The ANNEXA-4 study was successful in reducing factor Xa levels during time of administration but lacked correlation to improved patient outcomes. Given its novel mechanism of action, U.

Targeting abnormal metabolism in Alzheimer's disease: The Drug Repurposing for Effective Alzheimer's Medicines (DREAM) study.

Drug discovery for disease-modifying therapies for Alzheimer's disease and related dementias (ADRD) based on the traditional paradigm of experimental animal models has been disappointing. We describe the rationale and design of the Drug Repurposing for Effective Alzheimer's Medicines (DREAM) study, an innovative multidisciplinary alternative to traditional drug discovery. First, we use a systems biology perspective in the "hypothesis generation" phase to identify metabolic abnormalities that may either precede or interact with the accumulation of ADRD neuropathology, accelerating the expression of clinical symptoms of the disease.

Should Perturbation of the Preconceptive Environment be Considered a Risk Factor for the Development of Cardiovascular Disease Later in Life?

The anti-parkinsonian drug zonisamide reduces neuroinflammation: Role of microglial Na 1.6.

Parkinson's disease (PD), the second most common age-related progressive neurodegenerative disorder, is characterized by dopamine depletion and the loss of dopaminergic (DA) neurons with accompanying neuroinflammation. Zonisamide is an-anti-convulsant drug that has recently been shown to improve clinical symptoms of PD through its inhibition of monoamine oxidase B (MAO-B). However, zonisamide has additional targets, including voltage-gated sodium channels (Na), which may contribute to its reported neuroprotective role in preclinical models of PD.

Precise pathologic diagnosis and individualized treatment improve the outcomes of invasive micropapillary carcinoma of the breast: a 12-year prospective clinical study.

Invasive micropapillary carcinoma of the breast is a histologic subtype of breast cancer and associated with high incidence of lymphovascular invasion, lymph node metastasis and poor prognosis. The aim of this prospective study was to investigate the impact of precise pathologic diagnosis and individualized treatment on the outcomes of invasive micropapillary carcinoma of the breast. The study group included 2299 women with invasive micropapillary carcinoma diagnosed at Tianjin Medical University Cancer Institute and Hospital between January 2004 and December 2015.

FDA's Expedited Programs and Their Impact on the Availability of New Therapies.

The US Food and Drug Administration's (FDA's) Priority Review, Accelerated Approval, Fast Track, and Breakthrough Therapy programs have been successful in facilitating the drug approval process and getting medications to patients quicker. To qualify for one or more of these FDA programs, a sponsor must meet specific criteria. Once a drug is given one or more designations, benefits can range from frequent meetings with FDA representatives to appointed FDA senior managers to facilitate the approval process.

Protective effects of farnesoid X receptor (FXR) on hepatic lipid accumulation are mediated by hepatic FXR and independent of intestinal FGF15 signal.

Background & Aims: There is a growing evidence that bile acids are involved in the regulation of triglyceride-, cholesterol-homoeostasis and fat absorption. In this study organ-specific Fxr knockout mice were used to further investigate the influence of farnesoid X receptor FXR in lipogenesis.

Methods: Liver- and intestine-specific Fxr knockout mice were fed a 1% cholesterol diet for 28 days.
