The novel HLA-B*44:130 allele was found in a Spanish donor. B*44:130 differs from B*44:40 by four nucleotide changes at codons 11, 12 and 24, producing three amino acid replacements, 11A>S, 12M>V and 24T>S.

Background: Peripheral nerve sheath tumors (PNSTs) encompass entities with different cellular differentiation and degrees of malignancy. Spatial heterogeneity complicates diagnosis and grading of PNSTs in some cases. In malignant PNST (MPNST) for example, single cell sequencing data has shown dissimilar differentiation states of tumor cells.

Cytochromes of the P450 superfamily are widespread in nature; they were found in all studied aerobic organisms. Although the degree of similarity between cytochromes P450 of different families is low, all enzymes of this superfamily have similar tertiary structures. In addition, all cytochromes P450, including enzymes of the CYP74 clan, contain substrate recognition sites in their sequences, which form the catalytic center.

Cowpea (Vigna unguiculata) is recognized as a promiscuous legume in its symbiotic relationships with rhizobia, capable of forming associations with a wide range of bacterial species. Our study focused on assessing the diversity of bacterial strains present in cowpea nodules when inoculated with soils from six indigenous lands of Mato Grosso do Sul state, Central-Western Brazil, comprising the Cerrado and the Pantanal biomes, which are known for their rich diversity. The DNA profiles (BOX-PCR) of 89 strains indicated great genetic diversity, with 20 groups and 23 strains occupying single positions, and all strains grouped at a final similarity level of only 25%.

Background: Pancreatic ductal adenocarcinoma (PDAC) has a heterogeneous make-up of myeloid cells that influences the therapeutic response and prognosis. However, understanding the myeloid cell at both a genetic and cellular level remains a significant challenge.
Methods: Single-cell RNA sequencing (scRNA-seq) data were downloaded from t the Tumor Immune Single-cell Hub and gene expression data were retrieved from The Cancer Genome Atlas (TCGA) database and the Gene Expression Omnibus (GEO) database.

Background: TRIM28 plays a crucial role in maintaining genomic stability and establishing imprinting, facilitated by the diversity of KRAB zinc finger proteins. The SUMOylation of TRIM28 is essential for its function and is enhanced in the presence of the KRAB domain. Previously, we demonstrated that Kaiso, another factor capable of interacting with TRIM28, can promote its SUMOylation.
