RNA sequencing of CD11b+ mouse bone marrow cells in mice treated with exosomes with or without HDL mimicking nanoparticles

We report the sequencing of total RNA from CD11b+ mouse bone marrow cells in three groups of C57BL/6 mice: 1) Mice treated with three systemic (tail vein) injections (Days 1, 3, and 5) of phosphate buffered saline (PBS) (pH = 7.4), 2) Mice treated with three tail vein injections (Days 1, 3, and 5) of exosomes derived from enzalutamide resistant CWR-R1 prostate cancer cells (EnzR exosomes), and 3) Mice treated with three tail vein injections of EnzR exosomes (Days 1, 3, and 5) and high-density lipoprotein mimetic nanoparticles (HDL NPs) (Days 0, 2, and 4). Mice were sacrificed on Day 6, when mouse bone marrow was harvested and RNA from CD11b+ cells was obtained. We find that mice treated with EnzR exosome exhibit alteration in the expression of the matricellular protein, thrombospondin-1. Moreover, we find that HDL NP pre-treatment prevented thrombospondin-1 downregulation in mice treated with EnzR exosomes. This is consistent with our published findings that HDL NPs inhibit the uptake of EnzR exosomes by CD11b+ mouse bone marrow cells.
