Genome Editing Therapy for the Blood: Success and Prospects.

Hematopoietic stem cells (HSCs) provide the body with a continuous supply of healthy, functional blood cells. In patients with hematopoietic malignancies, immunodeficiencies, lysosomal storage disorders, and hemoglobinopathies, therapeutic genome editing offers hope for corrective intervention, with even modest editing efficiencies likely to provide clinical benefit. Engineered white blood cells, such as T cells, can be applied therapeutically to address monogenic disorders of the immune system, HIV infection, or cancer.

Peptide-enabled ribonucleoprotein delivery for CRISPR engineering (PERC) in primary human immune cells and hematopoietic stem cells.

Peptide-enabled ribonucleoprotein delivery for CRISPR engineering (PERC) is a new approach for ex vivo genome editing of primary human cells. PERC uses a single amphiphilic peptide reagent to mediate intracellular delivery of the same pre-formed CRISPR ribonucleoprotein enzymes that are broadly used in research and therapeutics, resulting in high-efficiency editing of stimulated immune cells and cultured hematopoietic stem and progenitor cells (HSPCs). PERC facilitates nuclease-mediated gene knockout, precise transgene knock-in, and base editing.

Nutritional Indexes as Predictors of Survival and Their Genomic Implications in Gastric Cancer Patients.

Gastric cancer is an aggressive malignancy with poor prognosis. Although obesity is a risk factor, an association between overweight and better survival has been reported. We explored the genomic implications of such association.

Identification of CFTR variants in Latino patients with cystic fibrosis from the Dominican Republic and Puerto Rico.

Background: In cystic fibrosis (CF), the spectrum and frequency of CFTR variants differ by geography and race/ethnicity. CFTR variants in White patients are well-described compared with Latino patients. No studies of CFTR variants have been done in patients with CF in the Dominican Republic or Puerto Rico.

The moderating role of age in the relationship between different stressors and the quality of life of the relatives of people with intellectual disabilities.

Purpose: The level of support needed for adaptive functioning and behavioral problems of individuals with intellectual disabilities (ID) can be a source of stress for caregivers. The aim of this study was to explore the moderating role of caregivers' age on the associations between these stressors and quality of life (QoL) of the family caregivers. As these sources of stress in people with ID can coexist, the triple interaction between stressors and age was also examined.
