The siRNA sequence targeting human JAM-A mRNA was designed and synthesized by RiboBio (Guangzhou, China), with a scrambled siRNA included as negative control.
The entire 3′-UTR of human JAM-A was amplified by PCR using human genomic DNA as the template, and the PCR products were inserted into the p-MIR-reporter plasmid (Ambion, Austin, TX, USA).
Considering that the 3′-UTR of human JAM-A is as long as 3.6 kb, we hypothesized that JAM-A expression may be down-regulated by miRNAs, such as miR-495, in breast cancer; indeed, a negative correlation between the expression of miR-495 and JAM-A was established in the present study.
Antibodies against mouse and human JAM-C have been previously described [ 17, 18].
We investigated JAM-C expression in human OA and RA synovial samples by IHC using polyclonal antibodies against human JAM-C.
To evaluate the potential use of blocking antibodies against human JAM-A, we then studied the biological activity of a commercially available human JAM-A-neutralizing antibody, J10.4 (Mandell et al, 2004), along with that of BV16 (produced in our laboratory) (Williams et al, 1999), in terms of their ability to dismantle JAM-A from endothelial junctions.
shRNA against the human JAM-A gene and a non-targeting shRNA as a control were cloned into pLKO.1 puro-based lentiviral vectors and purchased from Sigma-Aldrich (St Louis, MO, USA).
Mouse anti-human-E-selectin and anti-human-ICAM-1 antibodies and goat anti-human-VCAM-1 and anti-human-JAM-A antibodies (R&D, Minneapolis, MN, USA) were used at 2.5 μg/ml and plates were read using an ELISA reader (Bio-Rad, Hercules, CA, USA) set at 450 nm.
Many of them wind up in detention for little more than having been caught in a human traffic jam.
With so many people in the psychiatric wards, the human traffic jam spilled back to the emergency room.
That, in turn, led to a human traffic jam inside the airport — and to flight delays that continued through the day on Monday.
