Summary: This study successfully identified seven known crustacean allergens and up to 39 unreported allergens in different shrimp species through mining complete transcriptomes. Multiple sequence alignment revealed high homology of these shrimp allergens with allergens from other invertebrates such as mites and cockroaches. This first transcriptomic analyses of allergens in a major food source provides a valuable resource for investigating shellfish allergens, comparing invertebrate allergens and future development of improved diagnostics for food allergy.

Summary: The prevalence of vitamin A deficiency varies among different ethnic groups, potentially linked to single nucleotide polymorphism (SNP) allele frequencies associated with vitamin A metabolism. Significant differences were found in the VAD prevalence for Hispanic pregnant women between datasets. Genetic variants conferring risk for low retinol levels showed higher frequencies in populations with more VAD.

Summary: Long noncoding RNAs (lncRNAs) are extensively transcribed and studied, but those overlapping with mRNA in the sense orientation have been less explored. We investigated the lncRNA DAPALR overlapping with the 5' UTR of the male determining gene Doublesex1 (Dsx1) in Daphnia magna. Through affinity purification, we identified an RNA binding protein, Shep, as a DAPALR binding protein. Shep binds to Dsx1 5' UTR by recognizing the overlapping sequence and suppresses mRNA translation. In vitro and in vivo analyses indicated that DAPALR enhances Dsx1 translation efficiency by sequestering Shep. This mechanism may play a significant role in displaying dimorphic gene expressions, such as sex determination, and could explain binary expression in various developmental processes.

Summary: Vitamin D plays a critical role in calcium homeostasis, the immune system, and normal development. Many global epidemiological studies have found high prevalence rates of vitamin D deficiency and insufficiency, particularly in reproductive age and pregnant women. This study using a mouse model found that prenatal vitamin D deficiency increases the occurrence of liver histopathological changes and alters gene expression profiles, potentially contributing to offspring health risks.

Summary: This review discusses the decline in the use of umbilical cord blood (UCB) as a source of donor hematopoietic stem cells (HSC) for transplantation and emphasizes the potential of UCB and related birthing tissues for a wide range of therapies. When best practices are followed, UCB transplant can provide better survival and decreased risks compared to other donor sources. The review suggests that the potential of UCB for transplant and other cell-based therapies is undervalued and underutilized.

Summary: By studying the gene expression and chromatin states of human fibroblasts infected with Toxoplasma gondii, we gained insights into the molecular interactions between the intracellular pathogen and its host cell. We found that host cell genes were activated to regulate cellular processes, some of which were protective of the host cell while others were advantageous to the pathogen. Analysis of the host and parasite genomic information allowed us to annotate the T. gondii genome more accurately and discover new genes and cis-regulatory elements. By inferring the involved transcription factors and cell signaling responses in the host cell, we could understand how T. gondii perturbs host cell physiology.

Summary: The uptake of exome/genome sequencing has introduced challenges related to unexpected testing results, especially for pediatric patients, sparking debate on whether incidental findings should be returned. Identification and return of non-ACMG-recommended incidental findings in pediatric patients can be complex and difficult. While returning incidental genetic findings can benefit patients and providers, challenges and risks are also present.

Summary: It is believed that environmental influences can affect gene expression by altering epigenetic regulators of transcription. These epigenetic changes can be maintained long term and through cell division, resulting in a prolonged effect of the exposure. The evidence supporting this model comes from the observation of changes in molecular regulators of transcription following exposures. However, this model may be oversimplistic, and further research is needed to fully understand the complex associations between environmental exposures and phenotypes.
