Antibody generation requires the use of one or more time-consuming methods, namely animal immunization, and in vitro display technologies. However, the recent availability of large amounts of antibody sequence and structural data in the public domain along with the advent of generative deep learning algorithms raises the possibility of computationally generating novel antibody sequences with desirable developability attributes. Here, we describe a deep learning model for computationally generating libraries of highly human antibody variable regions whose intrinsic physicochemical properties resemble those of the variable regions of the marketed antibody-based biotherapeutics (medicine-likeness).

Article Synopsis
  • Normal tissues adjacent to breast tumors (NATs) may contain early signs of breast cancer development due to a phenomenon called field cancerization.
  • A study using advanced genomic techniques on samples from 43 breast cancer patients in Hong Kong revealed that NATs often had single-nucleotide variants (SNVs) in driver genes also found in tumor samples, but rarely had large-scale genomic changes.
  • The researchers identified different evolutionary patterns among NAT and tumor pairs, indicating distinct genomic characteristics and the influence of the tumor microenvironment on cancer development.

Article Synopsis
  • * A study identified a specific genetic variation at Chr6:31373718C>G that is associated with increased CRC risk, particularly in the younger population, with stronger odds for EOCRC compared to older adults.
  • * Analysis showed that individuals carrying the minor G allele have reduced expression of the immune-related MICA gene and lower levels of Natural Killer (NK) cell infiltration in tumors, suggesting a link between this genetic variation and tumor immune response.

Interpreting the phenotypes of alleles in genomes is complex. Whilst all strains are expected to carry a chromosomal copy conferring resistance to ampicillin, they may also carry mutations in chromosomal alleles or additional plasmid-borne alleles that have extended-spectrum β-lactamase (ESBL) activity and/or β-lactamase inhibitor (BLI) resistance activity. In addition, the role of individual mutations/a changes is not completely documented or understood.
