Myosin Vb as a tumor suppressor gene in intestinal cancer.

Colorectal cancer causes >900,000 deaths every year and a deeper understanding of the molecular mechanisms underlying this disease will contribute to improve its clinical management and survival. Myosin Vb (MYO5B) regulates intracellular vesicle trafficking, and inactivation of this myosin disrupts the polarization and differentiation of intestinal epithelial cells causing microvillous inclusion disease (MVID), a rare congenital disorder characterized by intractable life-threatening diarrhea. Here, we show that the loss Myosin Vb interfered with the differentiation/polarization of colorectal cancer cells.

LCOR mediates interferon-independent tumor immunogenicity and responsiveness to immune-checkpoint blockade in triple-negative breast cancer.

Ligand-dependent corepressor (LCOR) mediates normal and malignant breast stem cell differentiation. Cancer stem cells (CSCs) generate phenotypic heterogeneity and drive therapy resistance, yet their role in immunotherapy is poorly understood. Here we show that immune-checkpoint blockade (ICB) therapy selects for LCOR CSCs with reduced antigen processing/presentation machinery (APM) driving immune escape and ICB resistance in triple-negative breast cancer (TNBC).

Needs and Supports of People with Intellectual Disability and Their Families in Catalonia.

Background: The study assesses the support needs of individuals with intellectual disability and their families in Catalonia. The present authors examine family quality of life (FQoL), identify the individual services required and assess families' perceptions of the extent to which their family member with intellectual disability and they themselves receive the services they need.

Materials And Methods: The N&S questionnaire (Needs and Supports for people with intellectual disability and their families) was administered to 2160 families with a family member with intellectual disability aged under 70 in Catalonia (Spain).

Spanish family quality of life scales: under and over 18 years old.

Background: Researchers, professionals, and families have shown increasing concern with the family quality of life (FQoL) of people with intellectual disability (ID) and their families. The goals of this research were (a) to explore how Spanish families understand FQoL by developing 2 different measurement tools for families with a member with ID under and over 18 years old, and (b) to provide 2 diagnostic instruments that will be useful for designing action plans.

Method: The study comprised 4 stages: (a) focus groups, (b) expert assessment, (c) pilot study, and (d) normalisation and standardisation.
