Antisense oligonucleotide strategy reverses HNRNPH2-related neurodevelopmental disorder

Scientists at St. Jude Children's Research Hospital have found that they can reverse the effects of HNRNPH2-related neurodevelopmental disorder using antisense oligonucleotides (ASOs) in preclinical models. ASOs are short synthetic nucleic acid strands that target specific messenger RNA. In work published in Science Translational Medicine, the researchers show that ASOs block production of the aberrant HNRNPH2 protein. This consequently boosts expression of the closely related HNRNPH1 protein, reducing multiple symptoms of the disorder. The work provides vital mechanistic data to support the advancement of this promising therapy to clinical studies.

Discovery of a novel vulnerability in aggressive lymphoma could change future therapy

A research team at the University of Cologne's Center for Molecular Medicine Cologne (CMMC) has discovered that the protein cFLIP can be used to override the defenses of Diffuse Large B Cell Lymphoma (DLBCL) against programmed cell death. These defenses often cause treatments to be ineffective because they allow the cancer cells to survive. The results are especially relevant to ABC-DLBCL, a specific subtype of blood cancer that has poor patient prognosis and survival outcome. The new study appeared under the title "Expression of cFLIP in B cells is essential for diffuse large B cell lymphoma pathogenesis" in the Blood Journal.

Smell loss may mark Alzheimer’s start as olfactory damage map comes into focus

A research team has, for the first time, identified at the cellular level why the olfactory system is the first to be damaged in the early stages of Alzheimer's disease (dementia). The paper is published in the journal Alzheimer's & Dementia. The team was led by Prof. Moon Cheil of the Department of Brain Sciences at the Daegu Gyeongbuk Institute of Science and Technology, in collaboration with a team led by Prof. Ali Jahanshahi at Maastricht University in the Netherlands.

Scientists map 239 human-infective RNA viruses to track future outbreak risks

Researchers updated the global catalogue of human-infective RNA viruses to 239 ICTV-recognised species, incorporating taxonomy, discovery dates, locations, genome links, host range, transmissibility, and transmission routes. The dataset shows that most known human-infective RNA viruses remain strictly zoonotic, while only a minority are endemic in humans or capable of epidemic spread.

Pediatric heart transplant demand rises amid severe donor shortage

Advances in pediatric heart care are helping more children survive long enough to receive a transplant-but a critical shortage of donor hearts means too many are still dying while they wait, experts warned today at the International Society for Heart and Lung Transplantation (ISHLT) 46th Annual Meeting and Scientific Sessions.
