The Grab Bag Activity: A Student Coproduced Curriculum to Promote Professional Identity Development.

Objective: Describe a student coproduced curriculum to lay the foundation for professional identity development (PID).

Methods: Occurring during the introductory course of medical school, the Grab Bag Activity (GBA) is coordinated by upper-level students to offer informal, self-selected activities sponsored by upper-level students or faculty for incoming first-year students. Various levels of relationship are fostered: student to peer, student to near-peer, and student to faculty.

Endogenous interactomes of MFN1 and MFN2 provide novel insights into interorganelle communication and autophagy.

MFN1 (mitofusin 1) and MFN2 are key players in mitochondrial fusion, endoplasmic reticulum (ER)-mitochondria juxtaposition, and macroautophagy/autophagy. However, the mechanisms by which these proteins participate in these processes are poorly understood. Here, we studied the interactomes of these two proteins by using CRISPR-Cas9 technology to insert an HA-tag at the C terminus of MFN1 and MFN2, and thus generating HeLa cell lines that endogenously expressed MFN1-HA or MFN2-HA.

The stability of PCV2 virus-like particles from mammalian cells and challenges for biotechnological applications.

Porcine circovirus type 2 (PCV2) is a highly damaging pathogen for pig farming, causing significant economic losses. Despite the availability of vaccines based on different technologies, the virus steadily infects the world's pig population. In this context, virus-like particles (VLPs) constitute appealing alternatives for vaccine development as they lack the viral genome but present intact external surfaces.

Quantification of Histone H1 Subtypes Using Targeted Proteomics.

Histone H1 is involved in the regulation of chromatin structure. Human somatic cells express up to seven subtypes. The variability in the proportions of somatic H1s (H1 complement) is one piece of evidence supporting their functional specificity.
