The platelet-derived growth factor (PDGF) and its receptor, PDGFRα, are critical for tissue development and injury repair. To track PDGFRα-expressing cells in vivo, we generated a knock-in mouse line that expresses green fluorescent protein (GFP) under the control of the PDGFRα promoter. This genetic tool enabled us to detect PDGFRα expression in various organs during both neonatal and adult stages. Additionally, we confirmed the correlation between endogenous PDGFRα and transgenic PDGFRα expression using mouse injury models, showing the potential of this genetic reporter for studying PDGFRα-mediated signaling pathways and developing therapeutic strategies. Overall, the PDGFRα-GFP knock-in mouse line serves as a valuable tool for investigating the biology of PDGFRα and its role in normal development and disease.

Gestational diabetes mellitus (GDM), a transient form of diabetes that resolves postpartum, is a major risk factor for type 2 diabetes (T2D) in women. While the progression from GDM to T2D is not fully understood, it involves both genetic and environmental components. By integrating clinical, metabolomic, and genome-wide association study (GWAS) data, we identified associations between decreased sphingolipid biosynthesis and future T2D, in part through the allele of the gene in Hispanic women shortly after a GDM pregnancy.

Mesothelioma is a lethal cancer of the serosal lining of the body cavities. Risk factors include environmental and genetic factors. Asbestos exposure is considered the principal environmental risk factor, but other carcinogenic mineral fibers, such as erionite, also have a causal role.

Proto-oncogene KRAS, GTPase (KRAS) is one of the most intensively studied oncogenes in cancer research. Although several mouse models allow for regulated expression of mutant KRAS, selective isolation and analysis of transforming or tumor cells that produce the KRAS oncogene remains a challenge. In our study, we present a knock-in model of oncogenic variant KRAS that enables the "activation" of KRAS expression together with production of red fluorescent protein tdTomato.

Background: Alzheimer’s Disease (AD) has a strong spatial‐temporal component to its progression, where different brain regions are affected by amyloid‐beta (Aβ) plaque deposition at varying time points and in distinct cell types. Standard imaging and analysis platforms can neglect these details, as they lack the ability to pair high‐yield whole‐brain imaging with region‐specific or high‐resolution analysis. Here we describe a novel high‐throughput whole‐brain imaging pipeline to quantitatively track plaque progression as a function of brain region across time, while also producing indexed tissue sections for secondary staining and analysis that can be registered back to the original brain image.

Background: Studies of aging in non‐human primates are important to elucidate primate‐specific mechanisms underlying human aging, including pathological trajectories like Alzheimer’s disease (AD). Evidence of AD‐like brain aging has been reported across the primate order including amyloid beta (AB) deposits, but blood‐based biomarkers are less well‐studied. The goal of this project was to explore the use of validated assays for plasma biomarkers in two new non‐human primate species: coppery titi monkeys (Plecturocebus cupreus) and brown capuchins (Sapajus apella).
