DUSP12 promotes cell cycle progression and protects cells from cell death by regulating ZPR9.

Protein phosphatases are critical for regulating cell signaling, cell cycle, and cell fate decisions, and their dysregulation leads to an array of human diseases like cancer. The dual specificity phosphatases (DUSPs) have emerged as important factors driving tumorigenesis and cancer therapy resistance. DUSP12 is a poorly characterized atypical DUSP widely conserved throughout evolution.

Radiological and anatomical evaluation of the internal venous system in the context of access to the third ventricle - proposal of a new classification.

Background: The internal venous system of the brain is a crucial anatomical landmark during accesses to the third ventricle through the foramen of Monro. Many classifications based on radiological assessment of the system have been developed, but they tend to be descriptive and do not highlight favorable anatomical variants. The aim of our study was to create a system based on morphometric measurements to facilitate preoperative decision-making regarding access to third ventricle tumors.

Human REXO4 is Required for Cell Cycle Progression.

Human REXO4 is a poorly characterized exonuclease that is overexpressed in human cancers. To better understand the function of REXO4 and its relationship to cellular proliferation, we have undertaken multidisciplinary approaches to characterize its cell cycle phase-dependent subcellular localization and the cis determinants required for this localization, its importance to cell cycle progression and cell viability, its protein-protein association network, and its activity. We show that the localization of REXO4 to the nucleolus in interphase depends on an N-terminal nucleolar localization sequence and that its localization to the perichromosomal layer of mitotic chromosomes is dependent on Ki67.

In vivo Differential Effects of Extractable and Non-Extractable Phenolic Compounds from Grape Pomace on the Regulation of Obesity and Associated Metabolic Alterations.

Grape pomace (GP) is a by-product rich in phytochemicals, including extractable polyphenols (EPPs) and non-extractable polyphenols (NEPPs), which have distinct metabolic fates that may affect their biological activities. The benefits of GP have been reported in relation to obesity and its comorbidities, particularly when administered preventively focusing on EPPs. Therefore, the aim of this study was to investigate the effects of EPPs and NEPPs from GP as a treatment for obesity and its associated metabolic alterations.

Multimodal Inpatient Prehabilitation Prior to Heart or Lung Transplantation in a Latin American Transplant Reference Center.

Introduction: Whether the implementation of a multimodal prehabilitation program is effective and safe for high-risk heart or lung transplantation candidates, whose condition prevents hospital discharge, is unclear.

Methods: We conducted a retrospective study at a cardiothoracic transplant center in Chile. Two cohorts of hospitalized patients listed for heart or lung transplant were studied: the first underwent traditional (historical) and nonstructured prehabilitation, and the second underwent protocol-driven multimodal prehabilitation (MP).
