Alternative splicing dysregulation across tissue and therapeutic approaches in a mouse model of myotonic dystrophy type 1.

Myotonic dystrophy type 1 (DM1), the leading cause of adult-onset muscular dystrophy, is caused by a CTG repeat expansion. Expression of the repeat causes widespread alternative splicing (AS) defects and downstream pathogenesis, including significant skeletal muscle impacts. The mouse model plays a significant role in therapeutic development.

Myospreader improves gene editing in skeletal muscle by myonuclear propagation.

Successful CRISPR/Cas9-based gene editing in skeletal muscle is dependent on efficient propagation of Cas9 to all myonuclei in the myofiber. However, nuclear-targeted gene therapy cargos are strongly restricted to their myonuclear domain of origin. By screening nuclear localization signals and nuclear export signals, we identify "Myospreader," a combination of short peptide sequences that promotes myonuclear propagation.

Risky Decision Making Under Stressful Conditions: Men and Women With Smaller Cortisol Elevations Make Riskier Social and Economic Decisions.

Men often make riskier decisions than women across a wide range of real-life behaviors. Whether this sex difference is accentuated, diminished, or stable under stressful conditions is, however, contested in the scientific literature. A critical blind spot lies amid this contestation: Most studies use standardized, laboratory-based, cognitive measures of decision making rather than complex real-life social simulation tasks to assess risk-related behavior.

DSP30 and interleukin-2 as a mitotic stimulant in B-cell disorders including those with a low disease burden.

Chromosome abnormalities detected during cytogenetic investigations for B-cell malignancy offer prognostic information that can have wide ranging clinical impacts on patients. These impacts may include monitoring frequency, treatment type, and disease staging level. The use of the synthetic oligonucleotide DSP30 combined with interleukin 2 (IL2) has been described as an effective mitotic stimulant in B-cell disorders, not only in chronic lymphocytic leukemia (CLL) but also in a range of other B-cell malignancies.

Epitope mapping immunodominant regions of the PilA protein of nontypeable Haemophilus influenzae (NTHI) to facilitate the design of two novel chimeric vaccine candidates.

We designed and tested three PilA-derived vaccine candidates in a chinchilla model of ascending nontypeable Haemophilus influenzae (NTHI)-induced otitis media (OM). Delivery of antiserum directed against each immunogen conferred varying degrees of protection. Presentation of a B-cell epitope derived from the OMP P5 adhesin at the N-terminus of recombinant soluble PilA protein (as opposed to the C-terminus), resulted in a protective chimeric immunogen that combined epitopes from two distinct NTHI adhesins (type IV pili and OMP P5).
