The role of microenvironment-mediated biophysical forces in human lymphomas
remains elusive. Diffuse large B cell lymphomas (DLBCLs) are heterogeneous
tumors, which originate from highly proliferative germinal center B cells. These
tumors, their associated neo-vessels, and lymphatics presumably expose cells to
particular fluid flow and survival signals. Here, we show that fluid flow
enhances proliferation and modulates response of DLBCLs to specific therapeutic
agents. Fluid flow upregulates surface expression of B cell receptors (BCRs) and
integrin receptors in subsets of ABC-DLBCLs with either CD79A/B mutations or WT
BCRs, similar to what is observed with xenografted human tumors in mice. Fluid
flow differentially upregulates signaling targets, such as SYK and p70S6K, in
ABC-DLBCLs. By selective knockdown of CD79B and inhibition of signaling targets,
we provide mechanistic insights into how fluid flow mechanomodulates BCRs and
integrins in ABC-DLBCLs. These findings redefine microenvironment factors that
regulate lymphoma-drug interactions and will be critical for testing targeted
therapies.
