January 2025

Department of Nephrology, State Key Laboratory of Kidney Diseases, Beijing Key Laboratory of Kidney Disease Research, National Clinical Research Center for Kidney Diseases, Nephrology Institute of the Chinese People's Liberation Army, Chinese PLA General Hospital, Beijing, China.

Spaceflight-induced multi-organ dysfunction affects the health of astronauts and the safety of in-orbit flight. However, the effect of microgravity on the kidney and the underlying mechanisms are unknown. In the current study, we used a hindlimb unweighting (HU) animal model to simulate microgravity and employed histological analysis, ischemia-reperfusion experiments, renal ultrasonography, bioinformatics analysis, isometric force measurement, and other molecular experimental settings to evaluate the effects of microgravity on the kidneys and the underlying mechanisms involved in this transition.

Development of optical microneedle-lens array for photodynamic therapy.

Biomed Microdevices

January 2025

Institute of Industrial Science, The University of Tokyo, Meguro-Ku, 153-8505, Tokyo, Japan.

Recently, photodynamic therapy (PDT) which involves a photosensitizer (PS), a special drug activated by light, and light irradiation has been widely used in treating various skin diseases such as port-wine stain as well as cancers such as melanoma and non-melanoma skin cancers. PDT comprises two general steps: the introduction of PS into the body or a specific spot to be treated, and the irradiation process using a light source with a specific wavelength to excite the PS. Although PDT is gaining great attention owing to its potential as a targeted approach in the treatment of skin cancers, several limitations still exist for practical use.

Evidence suggests that sodium nitrite may be effective in the treatment of hypertension and pulmonary hypertension. However, its use remains debated due to safety concerns. In response, a scoping review was conducted to map current knowledge on the efficacy and safety of sodium nitrite in patients with hypertension or pulmonary hypertension, addressing the question: What evidence supports the effectiveness and safety of using sodium nitrite in these patients? The databases MEDLINE (PubMed), EMBASE, Scopus, Web of Science, and LILACS were searched for clinical studies on hypertensive patients at any disease stage without restrictions on age, sex, ethnicity, publication date, or status.

Development of Potent and Selective CK1α Molecular Glue Degraders.

J Med Chem

January 2025

Department of Chemical and Systems Biology, Stanford Cancer Institute, School of Medicine Stanford University, Stanford, California 94305-6104, United States.

Molecular glue degraders (MGDs) are small molecules that facilitate proximity between a target protein and an E3 ubiquitin ligase, thereby inducing target protein degradation. Glutarimide-containing compounds are MGDs that bind cereblon (CRBN) and recruit neosubstrates. Through explorative synthesis of a glutarimide-based library, we discovered a series of molecules that induce casein kinase 1 alpha (CK1α) degradation.

Aging and sex differences in salt sensitivity of blood pressure.

Clin Sci (Lond)

January 2025

Department of Medicine, Division of Clinical Pharmacology, Vanderbilt University Medical Center, Nashville, TN, U.S.A.

Salt sensitivity of blood pressure (SSBP) is a complex physiological trait characterized by changes in blood pressure in response to dietary salt intake. Aging introduces an additional layer of complexity to the pathophysiology of SSBP, with mitochondrial dysfunction, epigenetic modifications, and alterations in gut microbiota emerging as critical factors. Despite advancements in understanding these mechanisms, the processes driving increased salt sensitivity with age and their differential impacts across sexes remain unclear.

Hydrocortisone Attenuates the Development of Malformations of the Polymicrogyria Spectrum.

Int J Dev Neurosci

February 2025

Neurodegeneration and Repair Lab, Department of Pathology, Postgraduate Program in Anatomical Pathology, Faculty of Medicine, Universitary Hospital Clementino Fraga Filho, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil.

Most of the malformations of the polymicrogyria spectrum are caused by destructive lesions of the neocortex during the third trimester of pregnancy, triggered by hypoxic-ischemic, hemorrhagic or infectious events, with neuroinflammation as a common pathophysiological mechanism. Our study investigated hydrocortisone treatment in attenuating inflammation, malformations development and seizures predisposition in mice subjected to neonatal transcranial freeze lesion. Our results show attenuation of malformation and predisposition to febrile seizures, with concomitant reduction of macrophages/microglia after neonatal freeze lesion, polarizing them towards an anti-inflammatory profile.

Introduction: Antibiotic overuse is driving a global rise in antibiotic resistance, highlighting the need for robust antimicrobial stewardship (AMS) initiatives to improve prescription practices. While antimicrobials are essential for treating sepsis and preventing surgical site infections (SSIs), they can inadvertently disrupt the gut microbiota, leading to postoperative complications. Treatment methods vary widely across nations due to differences in drug choice, dosage, and therapy duration, affecting antibiotic resistance rates, which can reach up to 51% in some countries.

Comparative dissection of transcriptional landscapes of human iPSC-NK differentiation and NK cell development.

Life Med

August 2024

The Bone Marrow Transplantation Center of The First Affiliated Hospital &Liangzhu Laboratory, Zhejiang University School of Medicine, Hangzhou 310012, China.

Clinical and preclinical research has demonstrated that iPSC-derived NK (iNK) cells have a high therapeutic potential, yet poor understanding of the detailed process of their differentiation and their counterpart cell development has hindered therapeutic iNK cell production and engineering. Here we dissect the crucial differentiation of both fetal liver NK cells and iNK cells to enable the rational design of advanced iNK production protocols. We use a comparative analysis of single-cell RNA-seq (scRNA-seq) to pinpoint key factors lacking in the induced setting which we hypothesized would hinder iNK differentiation and/ or functionality.
