26913720 MiR-193a-3p and miR-193a-5p play important roles in osteosarcoma metastasis through down-regulation of the Rab27B and SRR genes and therefore may serve as useful biomarkers for the diagnosis of osteosarcoma

23217148 findings suggest that overexpression of Rab27B in BC coincides with lymph node metastasis and acquisition of a poor prognostic phenotype
22349512 These results suggest that Rab27b negatively regulates the cell surface expression of c-kit via secretion of SCF and that ligation of SCF leads to the endolysosomal degradation system of c-kit.
21304180 in human breast cancer specimens, the presence of Rab27B protein proved to be associated with a low degree of differentiation and the presence of lymph node metastasis in ER-positive breast cancer
21198862 were unable to find any mutation in the coding sequence of RAB27B in five patients suffering from different types of platelet delta-storage pool deficiency
20888820 Rab27b is associated with tubulovesicle membranes in the parietal cell and Rab27b may play a role in stimulation-associated membrane recruitment and gastric acid secretion.

18478159 During primate spermiogenesis, dynein, myosin Va, MyRIP and Rab27b that compose microtubule-based and actin-based vesicle transport systems are actually present in the manchette and might possibly be involved in intramanchette transport.
12122117 Rab27b is functionally redundant with Rab27a and the pathogenesis of Griscelli syndrome is determined by the relative expression of Rab27a and Rab27b in specialized cell types.
