The 2'-5'-oligoadenylate synthetases (OASs) are members of a family of interferon-induced proteins playing an important role in the antiviral effect of interferons as well as being involved in apoptosis and control of cellular growth. Based on sequence data from the murine BAC clone (RP23-39M18), and a number of EST and IMAGE clones and the Celera Mouse database, we identified twelve Oas genes in the mouse genome, all localized to the chromosome 5F region. In contrast to the single OAS1 gene found in humans, we identified eight closely linked Oas1 genes in the murine genome, together with the genes of Oas2 and Oas3. Compared to the single OASL gene found in humans, two genes of OAS-like proteins, Oasl1 and Oasl2, were identified. All the putative genes seem to be transcribed. The exon/intron structures of the murine Oas genes were found to be identical to those of the human genes.

Article Synopsis
- Hematologic malignancies significantly impact the health of children, young adults, and older adults, yet their biological causes are not well understood.
- A study revealed notable differences in clinical features and genomic mutations between children/young adults (CYAs) and older adults (OAs) in these diseases, including lower mutational burdens in CYAs for many key genes.
- The research identified specific genes with varying mutation rates and emphasized the need for age-oriented personalized treatment options based on the distinct genetic and clinical landscapes of CYAs and OAs.

Background: Breast cancer is the most common malignancy among women worldwide, characterized by complex molecular and cellular heterogeneity. Despite advances in diagnosis and treatment, there is an urgent need to identify reliable biomarkers and therapeutic targets to improve early detection and personalized therapy. The OAS (2'-5'-oligoadenylate synthetase) family genes, known for their roles in antiviral immunity, have emerged as potential regulators in cancer biology.

Article Synopsis
- Rice grains often have high arsenic levels and low essential nutrients, which can impact human health and nutrition.
- Researchers created genetically modified rice that expresses a mutant gene (astol1) to boost cysteine production and reduce arsenic accumulation.
- This modified rice showed increased essential nutrient levels and improved arsenic tolerance, suggesting a promising approach to both enhance nutrition and decrease toxicity in rice.
