The role of liver X receptors (LXR) in rheumatoid arthritis (RA) remains controversial. We studied the effect of LXR agonists on fibroblast-like synoviocytes (FLS) from RA patients and the K/BxN arthritis model in LXRα and β double-deficient (Nr1h2/3) mice. Two synthetic LXR agonists, GW3965 and T0901317, were used to activate LXRs and investigate their effects on cell growth, proliferation and matrix metalloproteinases, and chemokine production in cultured FLS from RA patients.

Introduction: The pathogenesis of Post-Transplant Diabetes Mellitus (PTDM) is complex and multifactorial and it resembles that of Type-2 Diabetes Mellitus (T2DM). One risk factor specific to PTDM differentiates both entities: the use of immunosuppressive therapy. Specifically, Tacrolimus interacts with obesity and insulin resistance (IR) in accelerating the onset of PTDM.

Article Synopsis
  • Autosomal polycystic kidney disease (ADPKD) is a genetic condition leading to kidney failure, with tolvaptan being the only approved treatment, but it's only for those with rapid disease progression.
  • A study assessed the accuracy of estimating GFR decline through serum creatinine and cystatin-C formulas, noting poor agreement with actual measured GFR declines using iohexol clearance.
  • This discrepancy means that about 37% of rapid GFR declines were missed, and many stable cases were wrongly identified as rapid progressors, which could lead to incorrect treatment decisions for tolvaptan therapy.

Article Synopsis
  • The study investigates the relationship between renal disease and metabolic syndrome (MS) by evaluating kidney histology in participants from the European Nephrectomy Biobank.
  • Researchers defined MS based on criteria like BMI, blood pressure, glucose levels, and cholesterol, excluding patients with diabetes or known renal disease.
  • Results show that individuals with MS are older, have a higher prevalence of chronic kidney disease, and display more severe renal morphological changes compared to those without MS, suggesting that ischemic renal disease and potential diabetic nephropathy may contribute to their kidney issues.

The default mode network is a central cortical brain network suggested to play a major role in several disorders and to be particularly vulnerable to the neuropathological hallmarks of Alzheimer's disease. Subcortical involvement in the default mode network and its alteration in Alzheimer's disease remains largely unknown. We performed a systematic review, meta-analysis and empirical validation of the subcortical default mode network in healthy adults, combined with a systematic review, meta-analysis and network analysis of the involvement of subcortical default mode areas in Alzheimer's disease.

TDP-43-M323K causes abnormal brain development and progressive cognitive and motor deficits associated with mislocalised and increased levels of TDP-43.

Neurobiol Dis

April 2024

Neurological Disorders Group, Hospital Clínico San Carlos, Instituto de Investigación Sanitaria Hospital Clínico San Carlos (IdiSSC), Madrid 28040, Spain; MRC Harwell Institute, Oxfordshire, UK. Electronic address:

TDP-43 pathology is found in several neurodegenerative disorders, collectively referred to as "TDP-43 proteinopathies". Aggregates of TDP-43 are present in the brains and spinal cords of >97% of amyotrophic lateral sclerosis (ALS), and in brains of ∼50% of frontotemporal dementia (FTD) patients. While mutations in the TDP-43 gene (TARDBP) are usually associated with ALS, many clinical reports have linked these mutations to cognitive impairments and/or FTD, but also to other neurodegenerative disorders including Parkinsonism (PD) or progressive supranuclear palsy (PSP).

Article Synopsis
  • A study was done to see if a type of screening test called FIT was better than the usual procedure, colonoscopy, for first-degree relatives of people with colorectal cancer.
  • The researchers wanted to know if more people would agree to take the FIT test compared to colonoscopy and if both tests would find the same number of serious issues.
  • The study was planned to involve many people over several years but had to stop early because it wasn't looking like it would have good results, even though they still gathered data for two years after.

Role of colonoscopy in colorectal cancer screening: Available evidence.

Best Pract Res Clin Gastroenterol

October 2023

Department of Gastroenterology of Hospital Universitario de Canarias, Instituto Universitario de Tecnologías Biomédicas (ITB) & Centro de Investigación Biomédica de Canarias (CIBICAN), Universidad de La Laguna, Spain. Electronic address:

Colonoscopy is the cornerstone examination for colorectal cancer (CRC) screening and it is recommended as the first examination in the context of individuals with high risk of CRC development. Thereby, this examination is of choice in the setting of patients with hereditary CRC syndromes or in patients with long-standing inflammatory bowel disease with colon involvement. However, its role is less clear in the average risk-risk population and in patients with family history of CRC not linked to hereditary CRC syndromes.

Background: Albuterol is the first-line asthma medication used in diverse populations. Although DNA methylation (DNAm) is an epigenetic mechanism involved in asthma and bronchodilator drug response (BDR), no study has assessed whether albuterol could induce changes in the airway epithelial methylome. We aimed to characterize albuterol-induced DNAm changes in airway epithelial cells, and assess potential functional consequences and the influence of genetic variation and asthma-related clinical variables.
