GENCODE produces comprehensive reference gene annotation for human and mouse. Entering its twentieth year, the project remains highly active as new technologies and methodologies allow us to catalog the genome at ever-increasing granularity. In particular, long-read transcriptome sequencing enables us to identify large numbers of missing transcripts and to substantially improve existing models, and our long non-coding RNA catalogs have undergone a dramatic expansion and reconfiguration as a result.

Article Synopsis
  • - Accurate gene annotations are essential for interpreting how genomes function, and the GENCODE consortium has spent twenty years creating reference annotations for human and mouse genomes, serving as a vital resource for researchers globally.
  • - Previous annotations of long non-coding RNAs (lncRNAs) were incomplete and poorly organized, hindering research, prompting GENCODE to launch a comprehensive effort that resulted in adding nearly 18,000 novel human genes and over 22,000 novel mouse genes, significantly increasing the catalog of transcripts.
  • - The new annotations not only show evolutionary patterns and link to genetic variants associated with traits but also improve understanding of previously unclear genomic functions, greatly advancing research into both human and mouse genetic diseases.

Despite extensive characterization of mammalian Pol II transcription, the DNA sequence determinants of transcription initiation at a third of human promoters and most enhancers remain poorly understood. We trained and interpreted a neural network called ProCapNet that accurately models base-resolution initiation profiles from PRO-cap experiments using local DNA sequence. ProCapNet learns sequence motifs with distinct effects on initiation rates and TSS positioning and uncovers context-specific cryptic initiator elements intertwined within other TF motifs.

Patients with pre-existing immunity to adeno-associated virus (AAV) are currently unable to receive systemic gene transfer therapies. In this nonhuman primate study, we investigated the impact of immunosuppression strategies on gene transfer therapy safety and efficacy and analyzed plasmapheresis as a potential pretreatment for circumvention of pre-existing immunity or redosing. In part 1, animals received delandistrogene moxeparvovec (SRP-9001), an AAVrh74-based gene transfer therapy for Duchenne muscular dystrophy.

Article Synopsis
  • Scientists are studying how DNA sequences work to control gene expression in different cell types, but it's been hard to figure out how these sequences affect gene activity.
  • They created a new method called Variant-FlowFISH to test many tiny changes in DNA and see how they change gene expression, using advanced tools like CRISPR.
  • By testing 672 different changes, they found that many can really change gene activity, and some changes work differently in different types of cells, which helps improve predictions about how genes are controlled.

With increasing water scarcity, many utilities are considering the potable reuse of wastewater as a source of drinking water. However, not all chemicals are removed in conventional wastewater treatment, and disinfection byproducts (DBPs) can form from these contaminants when disinfectants are applied during or after reuse treatment, especially if applied upstream of advanced treatment processes to control biofouling. We investigated the chlorination of seven priority emerging contaminants (17β-estradiol, estrone, 17α-ethinylestradiol, bisphenol A (BPA), diclofenac, -nonylphenol, and triclosan) in ultrapure water, and we also investigated the impact of chlorination on real samples from different treatment stages of an advanced reuse plant to evaluate the role of chlorination on the associated cytotoxicity and estrogenicity.

Maternal HPA axis dysregulation during early pregnancy can negatively affect maternal functioning. However, findings are mixed regarding how intimate partner violence (IPV), a common traumatic stressor, impacts HPA axis regulation during pregnancy. Interactions between IPV and mental health symptoms as they influence cortisol production are rarely examined, especially among pregnant women.

Objective: Intimate partner violence (IPV) during pregnancy is associated with negative physical and mental health consequences for both mothers and infants. Economic hardship is often exacerbated during pregnancy and is associated with increased rates of IPV in non-pregnant samples. However, temporal associations between economic hardship and IPV victimization have not been well characterized during pregnancy.

The evolution of virtual reality (VR) has created the opportunity for a relatively low-cost and accessible method to practice motor skills. Previous studies have demonstrated how motor skill practice in non-immersive virtual environments transfers to physical environments. Though minimal research has investigated motor learning and transfer within immersive VR, multiple experiments provide empirical evidence of positive transfer effects.

Numerous studies associate childhood exposure to intimate partner violence (IPV) with adverse adjustment in the domains of mental health, social, and academic functioning. This review synthesizes this literature and highlights the critical role of child self-regulation in mediating children's adjustment outcomes. We discuss major methodological problems of the field, including failure to consider the effects of prenatal IPV exposure and the limitations of variable-oriented and cross-sectional approaches.

Article Synopsis
  • Protein drugs are usually too big to be taken by mouth, so scientists are looking for ways to help them be absorbed in the stomach.
  • They studied some special substances called permeation enhancers to see if they are safe for mice when used every day for 30 days.
  • The results showed that the mice stayed healthy, gained weight, and using these enhancers might actually be safe for long-term use without causing problems to their intestines.

Although patients generally prefer oral drug delivery to injections, low permeability of the gastrointestinal tract makes this method impossible for most biomacromolecules. One potential solution is codelivery of macromolecules, including therapeutic proteins or nucleic acids, with intestinal permeation enhancers; however, enhancer use has been limited clinically by modest efficacy and toxicity concerns surrounding long-term administration. Here, we hypothesized that plant-based foods, which are well tolerated by the gastrointestinal tract, may contain compounds that enable oral macromolecular absorption without causing adverse effects.

Circular RNAs (circRNAs) are a vast class of covalently closed, noncoding RNAs expressed in specific tissues and developmental stages. The molecular, cellular, and pathophysiologic roles of circRNAs are not fully known, but their impact on gene expression programs is beginning to emerge, as circRNAs often associate with RNA-binding proteins and nucleic acids. With rising interest in identifying circRNAs associated with disease processes, it has become particularly important to identify circRNAs in RNA sequencing (RNA-seq) datasets, either generated by the investigator or reported in the literature.

Article Synopsis
  • The study investigates how well transcription factor (TF) binding predictions can be applied across different species, given that their DNA sequence preferences are often conserved.
  • Researchers train neural networks to differentiate actual TF binding sites from random genomic locations and find that predictions are less accurate between different species due, in part, to species-specific repeats.
  • By using a modified network architecture that minimizes the influence of these species-specific features, the study improves the accuracy of cross-species TF binding predictions, showing that it is possible when accounting for these variations.
