Michel Foucault's concept of the dispositif is increasingly salient in sociological scholarship. We identify and criticise an 'anonymous' emphasis in this scholarship, which often presents the dispositif as an anonymous network that acts without human agents. To remedy this tendency we develop an agent-inclusive version of the dispositif for sociological research.

Impacts of City Life on Nutrition: Evidence From Resettlement Lotteries in China.

Health Econ

January 2025

Department of Agricultural and Applied Economics, University of Georgia, Athens, Georgia, USA.

Urban environments are thought to improve food security, by offering enhanced access to markets and income opportunities. Yet this idea is hard to test empirically due to an abundance of confounding factors and selection issues. This study leverages a resettlement program in China to provide the first quasi-experimental estimate of city life on food consumption and nutrition among low-income households.

Fate erasure logic of gene networks underlying direct neuronal conversion of somatic cells by microRNAs.

Cell Rep

January 2025

Department of Developmental Biology, Washington University School of Medicine, St. Louis, MO 63110, USA; Center of Regenerative Medicine, Washington University School of Medicine, St. Louis, MO 63110, USA. Electronic address:

Neurogenic microRNAs 9/9 and 124 (miR-9/9-124) drive the direct reprogramming of human fibroblasts into neurons with the initiation of the fate erasure of fibroblasts. However, whether the miR-9/9-124 fate erasure logic extends to the neuronal conversion of other somatic cell types remains unknown. Here, we uncover that miR-9/9-124 induces neuronal conversion of multiple cell types: dura fibroblasts, astrocytes, smooth muscle cells, and pericytes.

SLC7A5 is required for cancer cell growth under arginine-limited conditions.

Cell Rep

January 2025

Department of Biochemistry, University of Utah, Salt Lake City, UT 84112, USA; Huntsman Cancer Institute, University of Utah, Salt Lake City, UT 84112, USA. Electronic address:

Tumor cells must optimize metabolite acquisition between synthesis and uptake from a microenvironment characterized by hypoxia, lactate accumulation, and depletion of many amino acids, including arginine. We performed a metabolism-focused functional screen using CRISPR-Cas9 to identify pathways and factors that enable tumor growth in an arginine-depleted environment. Our screen identified the SLC-family transporter SLC7A5 as required for growth, and we hypothesized that this protein functions as a high-affinity citrulline transporter.

Here, we present a protocol to alter the production of alternatively spliced mRNA variants, without affecting the overall gene expression, through CRISPR-Cas9-engineered genomic mutations in mice. We describe steps for designing guide RNA to direct Cas9 endonuclease to consensus splice sites, producing transgenic mice through pronuclear injection, and screening for desired mutations in cultured mammalian cells using a minigene splicing reporter. Splice isoform-specific mouse mutants provide valuable tools for genetic analyses beyond loss-of-function and transgenic alleles.
