Direct targeting of noncoding genomic regions harboring common sequence variants associated with human traits through in vivo animal model studies and precise genome editing in human cells is essential for closing the critical gap between genetic discoveries and physiological understanding. However, such investigation has been impractical for many of these variants as they are in haplotypes containing multiple single-nucleotide polymorphisms (SNPs) spanning thousands of base pairs and have small effect sizes. We developed an integrated approach to address this challenge, combining an efficient two-step technique to precisely edit large haplotypes in human induced pluripotent stem cells and orthologous region deletion …

Castration-resistant prostate cancer (CRPC) remains an incurable disease in need of improved treatments. CAMKK2 is an emerging therapeutic target whose oncogenic effects in prostate cancer have, to date, been largely attributed to its activation of AMP-activated protein kinase (AMPK). Here, we demonstrate that CAMKK2 promotes prostate cancer growth through an alternative downstream pathway involving CAMKI and CREB. Unbiased transcriptomics identify CREB-mediated transcription as a CAMKK2-regulated process, findings that we validate using diverse molecular, genetic, and pharmacological approaches in vitro and in vivo. CAMKK2 promotes CREB phosphorylation/activation through CAMKIα independently of AMPK, CAMKIV, or other CAMKI isoforms. Functionally, the CREB family …

Age-related macular degeneration (AMD) is a leading cause of blindness in people over 50. AMD and cardiovascular disease share risk factors including age, impaired lipid metabolism, and extracellular lipid deposition. Because of its importance in age-related diseases, we hypothesize that apolipoprotein M (ApoM), a lipocalin that binds sphingosine-1-phosphate (S1P), might restore lipid homeostasis and retinal function in AMD. In support, we find that human patients with AMD demonstrate significantly reduced ApoM compared to controls. In mice with impaired retinal cholesterol efflux, ApoM improves retinal pigment epithelium (RPE) function and lipotoxicity in an S1P- and S1P receptor 3-dependent manner. Ultrastructural evidence …

The omentum is a visceral adipose tissue that undergoes dynamic immunological changes prior to and following metastasis. Here, we present a protocol for assessing the mobilization of peritoneal B cells to the pre-metastatic omentum in a mouse ovarian cancer model. We describe steps for isolation and adoptive transfer of peritoneal donor B cells and their detection in the omentum of recipient mice. This protocol could be utilized to study the mobilization of peritoneal B cells to the omentum in other pathological contexts. For complete details on the use and execution of this protocol, please refer to Lee et al.

The clinical neurosciences are in the midst of a renaissance spurred by the development of new therapeutic modalities. Short interfering RNAs (siRNAs), in particular, are gaining interest for treating neurological diseases owing to their capacity to sustain inhibition of nearly any gene target. However, to be effective, siRNA therapies must achieve delivery and on-target gene silencing activity in specific sites and cells in the brain. To this end, we developed a lipid-siRNA conjugate (L2-siRNA) that transports effectively throughout the brain when injected into cerebrospinal fluid (CSF). We provide a detailed examination of regional bulk tissue gene silencing in mice, highlighting …

The brain's endocannabinoid signaling system modulates a diverse range of physiological phenomena and is also involved in various psychiatric and neurological disorders. The basic components of the molecular machinery underlying endocannabinoid-mediated synaptic signaling have been known for decades. However, limitations associated with the short-lived nature of endocannabinoid lipid signals had made it challenging to determine the spatiotemporal specificity and dynamics of endocannabinoid signaling in vivo. Here, we discuss how novel technologies have recently enabled unprecedented insights into endocannabinoid signaling taking place at specific synapses in behaving animals. In this review, we primarily focus on cannabinoid-sensitive inhibition in the hippocampus in …

Human norovirus is the leading cause of viral gastroenteritis across all age groups. While there is a need for human norovirus antivirals, therapeutic development has been hindered by a lack of cell culture systems and animal models of infection. Surrogate viruses, such as Tulane virus (TV), have provided tractable systems to screen potential antiviral compounds. Our previous work demonstrated that TV encodes a viral ion channel, which dysregulates cytosolic calcium signaling. We set out to investigate whether host pathways triggered by viral ion channel activity, including store-operated calcium entry (SOCE), play a role in virus replication. Using pharmacologic inhibitors and …
