The permissive binding theory of cancer.

The later stages of cancer, including the invasion and colonization of new tissues, are actively mysterious compared to earlier stages like primary tumor formation. While we lack many details about both, we do have an apparently successful explanatory framework for the earlier stages: one in which genetic mutations hold ultimate causal and explanatory power. By contrast, on both empirical and conceptual grounds, it is not currently clear that mutations alone can explain the later stages of cancer.

Impact of the Affordable Care Act on Prescription Contraceptive Use and Costs Among Privately Insured Women, 2006-2020.

Background: In the years immediately following the Affordable Care Act (ACA)'s contraceptive coverage requirement, out-of-pocket costs fell for all Food and Drug Administration-approved contraceptive methods and use of long-acting reversible contraception (LARC) increased. This analysis examines whether these trends have continued through 2020 for privately insured women.

Methods: Using 2006-2020 MarketScan data, we examined trends in prescription contraceptive use and out-of-pocket costs among women 13 to 49 years old.

Mixing genome annotation methods in a comparative analysis inflates the apparent number of lineage-specific genes.

Comparisons of genomes of different species are used to identify lineage-specific genes, those genes that appear unique to one species or clade. Lineage-specific genes are often thought to represent genetic novelty that underlies unique adaptations. Identification of these genes depends not only on genome sequences, but also on inferred gene annotations.

Defining characteristics and conservation of poorly annotated genes in Caenorhabditis elegans using WormCat 2.0.

Omics tools provide broad datasets for biological discovery. However, the computational tools for identifying important genes or pathways in RNA-seq, proteomics, or GWAS (Genome-Wide Association Study) data depend on Gene Ontogeny annotations and are biased toward well-described pathways. This limits their utility as poorly annotated genes, which could have novel functions, are often passed over.

The Origins and Functions of De Novo Genes: Against All Odds?

"De novo" genes evolve from previously non-genic DNA. This strikes many of us as remarkable, because it seems extraordinarily unlikely that random sequence would produce a functional gene. How is this possible? In this two-part review, I first summarize what is known about the origins and molecular functions of the small number of de novo genes for which such information is available.
