Common and Sex-Biased Muscle Transcriptomic Aging Signatures Across Diverse Species

The paper identifies common and sex-biased aging biomarkers in skeletal muscle transcriptomes across six species, revealing shared and divergent molecular mechanisms of aging.

Wrong but useful: Bombyx silkworm W chromosome assemblies are flawed but still capture strongly reduced diversity of repetitive DNA

The paper evaluates W chromosome assemblies in Bombyx mori, finding them structurally flawed but revealing reduced repetitive DNA diversity and rapid repeat turnover.

Comparative Transcriptomic Analysis of Embryonic Stem Cells (ESCs) across Mammalian Species

This study compares transcriptomic profiles of embryonic stem cells across mammals, identifying conserved and species-specific pluripotency mechanisms and markers.

Sex-biased Transcriptome in in vitro Produced Bovine Early Embryos

This study identifies sex-biased gene expression, alternative splicing, and isoform dynamics in bovine embryos, linking male-biased metabolism to faster development and female-biased X-linked gene expression to sex-specific regulation.

Ghost W chromosomes and unique genome architecture in ghost moths of the family Hepialidae

This study investigates the W chromosome in ghost moths, revealing large genomes, absence of typical sex chromatin, and potential origin from a B chromosome.

Genome sequence of Ophryocystis elektroscirrha, an apicomplexan parasite of monarch butterflies: cryptic diversity and response to host-sequestered plant chemicals

The paper sequences the genome of Ophryocystis elektroscirrha, a monarch butterfly parasite, revealing its small genome size, gene loss, and potential evolutionary responses to host plant chemicals.

Transcriptomics of monarch butterflies (Danaus plexippus) reveals strong differential gene expression in response to host plant toxicity, but weak response to parasite infection

This study examines gene expression in monarch butterflies exposed to toxic and non-toxic milkweeds, finding strong responses to plant toxins but weak responses to parasite infection.

Contrasting Patterns Of Evolutionary Constraint And Novelty Revealed By Comparative Sperm Proteomic Analysis

The paper compares sperm proteomes across Lepidoptera species to reveal evolutionary patterns of constraint and novelty in spermatogenesis.

Neo-sex chromosomes in the Monarch butterfly, Danaus plexippus

The paper identifies a neo-sex chromosome in the Monarch butterfly and its relatives, using sequencing coverage and ortholog counts to assign chromosomes and detect assembly errors.
