The novel ECM protein SNED1 mediates cell adhesion via the RGD-binding integrins α5β1 and αvβ3.

The extracellular matrix (ECM) is a complex meshwork comprising over 100 proteins. It serves as an adhesive substrate for cells and, hence, plays crucial roles in health and disease. We have recently identified a novel ECM protein, SNED1, and have found that it is required for neural crest cell migration and craniofacial morphogenesis during development and in breast cancer, where it is necessary for the metastatic dissemination of tumor cells.

CRISPR-Edited DPSCs, Constitutively Expressing BDNF Enhance Dentin Regeneration in Injured Teeth.

Dental caries is one of the most common health issues worldwide arising from the complex interactions of bacteria. In response to harmful stimuli, desirable outcome for the tooth is the formation of tertiary dentin, a protective reparative process that generates new hard tissue. This reparative dentinogenesis is associated with significant inflammation, which triggers the recruitment and differentiation of dental pulp stem cells (DPSCs).

Occurrence, bioaccumulation and trophodynamics of per- and polyfluoroalkyl substances (PFAS) in terrestrial and marine ecosystems of Svalbard, Arctic.

Per- and polyfluoroalkyl substances (PFAS) enter the Arctic through long-range transport and local pollution. To date, little is known about their behavior in plant and benthic marine food webs in remote Arctic. In this study, we analyzed the environmental distribution and nutrient transfer of 20 PFAS in soil, sediment, plant and benthic biota samples collected between 2014 and 2016 in Svalbard, Arctic.

Increasing financial incentives can lower the cost of trial recruitment.

Monetary incentives are commonly used to help recruit trial participants. Some studies have found greater recruitment with larger incentives, while others have found smaller incentives more cost-effective in terms of cost per participant. As part of an implementation study, we compared the impact of four approaches to recruitment, three of which involved phone recruitment with varying financial incentives.

Radial artery mechanical thrombectomy for transradial approach in neurointerventions: a step-by-step technical report.

Radial artery occlusion (RAO) is a relatively common but benign complication following transradial endovascular approaches. Radial artery thrombectomy offers a potential strategy for re-access. Transradial access in the occluded vessel has been described as safe and feasible in recent literature; however, the step-by-step technical details have not been defined.

Encapsulation and Delivery of the Kinase Inhibitor PIK-75 by Organic Core High-Density Lipoprotein-Like Nanoparticles Targeting Scavenger Receptor Class B Type 1.

PIK-75 (F7) is a potent multikinase inhibitor that targets p110α, DNA-PK, and p38γ. PIK-75 has shown potential as a therapy in preclinical cancer models, but it has not been used in the clinic, at least in part, due to limited solubility. We therefore developed a nanoparticle to encapsulate PIK-75 and enable targeted cellular delivery.

Neurogenic Aging After Spinal Cord Injury: Highlighting the Unique Characteristics of Aging After Spinal Cord Injury.

Emanating from several decades of study into the effects of the aging process after spinal cord injury (SCI), "accelerated aging" has become a common expression as the SCI accelerates the onset of age-related pathologies. However, the aging process follows a distinct trajectory, characterized by unique patterns of decline that differ from those observed in the general population without SCI. Aging brings significant changes to muscles, bones, and hormones, impacting overall physical function.

MicroRNA Nobel Prize: Timely Recognition and High Anticipation of Future Products-A Prospective Analysis.

MicroRNAs (miRNAs) maintain cellular homeostasis by blocking mRNAs by binding with them to fine-tune the expression of genes across numerous biological pathways. The 2024 Nobel Prize in Medicine and Physiology for discovering miRNAs was long overdue. We anticipate a deluge of research work involving miRNAs to repeat the history of prizes awarded for research on other RNAs.

Advancing Therapeutic and Vaccine Proteins: Switching from Recombinant to Ribosomal Delivery-A Humanitarian Cause.

Recombinant therapeutic and vaccine proteins have revolutionized healthcare, but there remain challenges, as many are awaiting development due to their slow development speed and high development cost. Cell-free in vivo ribosomes offer one choice, but they come with similar constraints. The validation of in vivo messenger RNA (mRNA) technology has been accomplished for COVID-19 vaccines.

The Presence of Added Sugars and Other Sweeteners in Food and Beverage Products Advertised on Television in the United States, 2022.

Background/objectives: The Dietary Guidelines for Americans recommend consuming less than 10% of total calories from added sugars. Low-calorie sweeteners, sugar alcohols, and natural low-calorie sweeteners are used to reduce added sugar intake, but there are concerns about their long-term health impacts, especially for children. This paper describes the food and beverage television advertising landscape as it pertains to sweeteners.

Senescence and Stress Signaling Pathways in Corneal Cells After Nitrogen Mustard Injury.

Mustard gas keratopathy (MGK), a complication of exposure to sulfur mustard, is a blinding ocular surface disease involving key cellular pathways, including apoptosis, oxidative stress, and inflammation. Recent studies indicate that cellular senescence contributes to the pathophysiology of mustard gas toxicity. This study aimed to assess senescence and stress-related pathways-particularly mitogen-activated protein kinase (MAPK) signaling-in nitrogen mustard (NM)-induced corneal injury.

Enhancing Glioblastoma Resection with NIR Fluorescence Imaging: A Systematic Review.

Glioblastoma (GB) is among the most aggressive and difficult-to-treat brain tumors, with a median survival of only 12-15 months despite maximal treatments, including surgery, radiotherapy, and chemotherapy. Extensive surgical resection improves survival in glioblastoma patients; however, achieving complete resection is often hindered by limitations in neurosurgical guidance technologies for accurate tumor margin detection. Recent advancements in fluorescence-guided surgery (FGS) and imaging techniques have significantly enhanced the precision and extent of glioblastoma resections.

Guardians at the Gate: Optimization of Small Molecule Entry Inhibitors of Ebola and Marburg Viruses.

Ebola and Marburg (EBOV and MARV) filoviral infections lead to fatal hemorrhagic fevers and have caused over 30 outbreaks in the last 50 years. Currently, there are no FDA-approved small molecule therapeutics for effectively treating filoviral diseases. To address this unmet medical need, we have conducted a systematic structural optimization of an early lead compound, -(4-(4-methylpiperidin-1-yl)-3-(trifluoromethyl)phenyl)-4-(morpholinomethyl)benzamide (), borne from our previously reported hit-to-lead effort.
