AI Article Synopsis

  • Leukocytes migrate by re-using adhesion molecules called integrins, which are transported to the cell membrane through processes called endocytosis and exocytosis.
  • The transportation of these integrins is regulated by small GTPases, with RhoB playing a key role in the process.
  • This text describes an activation assay for RhoB in leukocytes using Rhoteikin coated agarose beads on ICAM-1Fc dishes, which can also be applied to other factors that induce RhoB activation.

Article Abstract

To be able to migrate, leukocyte needs to re-use its adhesion molecules to move forward. These adhesion molecules are called integrins and are intracellularly transported via endocytosis and exocytosis in order to translocate to a new site on the cell membrane. The intracellular transportation is regulated by different small GTPases including RhoB. Here we describe an activation assay of RhoB in leukocytes migrating on ICAM-1Fc coated dishes using commercially available Rhoteikin coated agarose beads. Although this is a specific protocol for LFA-1 induced RhoB activation, it can also be used for RhoB activation induced by other soluble and insoluble factors.

The progression and outcome of bladder cancer (BLCA) are critically affected by the propensity of tumor metastasis. Our previous study revealed that activation of the mevalonate (MVA) pathway promoted migration of BLCA cells; however, the exact mechanism is unclear. Here we show that elevated expression of MVA pathway enzymes in BLCA cells, correlating with poorer patient prognosis by analyzing single-cell and bulk-transcriptomic datasets.

Cell-cell adhesion in endothelial monolayers is tightly controlled and crucial for vascular integrity. Recently, we reported on the importance of fast protein turnover for maintenance of endothelial barrier function. Specifically, continuous ubiquitination and degradation of the Rho GTPase RhoB is crucial to preserve quiescent endothelial integrity.

This study was aimed at exploring a specific open region of chromatin in the peripheral blood mononuclear cells (PBMCs) of patients with breast cancer and evaluating its feasibility as a biomarker for diagnosing and predicting breast cancer prognosis. We obtained PBMCs from breast cancer patients and healthy people for the assay for transposase-accessible chromatin (ATAC) sequencing (n = 3) and obtained the GSE27562 chip sequencing data for secondary analyses. Through bioinformatics analysis, we mined the pattern changes for chromatin accessibility in the PBMCs of breast cancer patients.

Inhibition of translation initiation using eIF4A inhibitors like (-)-didesmethylrocaglamide [(-)-DDR] and (-)-rocaglamide [(-)-Roc] is a potential cancer treatment strategy as they simultaneously diminish multiple oncogenic drivers. We showed that human and dog osteosarcoma cells expressed higher levels of eIF4A1/2 compared with mesenchymal stem cells. Genetic depletion of eIF4A1 and/or 2 slowed osteosarcoma cell growth.
