Gene-rich fungus gnat germline-restricted chromosomes are largely transcriptionally quiescent

Germline-restricted chromosomes (GRCs) constitute a unique class of chromosomes confined to germ cells. Arising in multiple evolutionarily distant lineages, GRCs have been identified in three insect families (non-biting midges, gall midges, and fungus gnats), each within the orde...

A randomized phase II study of fulvestrant with or without ganetespib in patients with endocrine resistant metastatic breast cancer

Abstract Background Patients with endocrine-resistant hormone receptor-positive (HR+), HER2-negative metastatic breast cancer (MBC) have limited effective treatment options. Heat shock protein 90 (HSP90) regulates estrogen receptor stability and function; its inhibition has been...

Protocol for high-sensitivity detection of microRNAs in adult Drosophila tissues using hybridization chain reaction

MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression and cell-fate determination. Here, we present a protocol for detecting miRNAs in Drosophila gonadal tissues using an optimized hybridization chain reaction (HCR)-based approach. We describe steps for using...

Reconstructing signaling histories of single cells via perturbation screens and transfer learning

Manipulating the signaling environment is an effective approach to alter cellular states for broad-ranging applications, from engineering tissues to treating diseases. Such manipulation requires knowing the signaling states and histories of the cells in situ , for which high-thro...

High-throughput engineering of bispecific antibodies to enhance macrophage-mediated cytotoxicity of B-cell lymphoma

Abstract Macrophages are critical effectors of antibody therapies for lymphoma, but the best targets to engage their function remain unknown. Here, we develop a ‘tactical surfaceome profiling’ strategy to define a comprehensive repertoire of surface antigens on B-cell lymphoma th...
