abstract = {This study aims to identify by a molecular genetic approach
potential targets in mast cells at which 1,4-benzodiazepines
may cause their inhibitory effect on mast cell activity.Gene
expression analyses with microarray gene chip and/or
quantitative PCR were performed using
1,4-benzodiazepine-treated human mast cell leukemia HMC-1.2
cells, promyelocytic leukemia HL-60 cells and human mast
cells from healthy volunteers and patients with mast cell
activation disease (MCAD). Pathway analysis was applied to
search for enriched biological functions and canonical
pathways within differentially regulated genes.Both
neoplastic and normal human mast cells express several
GABA(A) receptor subunits at the mRNA level. In mast cells
from MCAD patients expression of some GABA(A) receptor
subunits and expression of the translocator protein TSPO are
increased compared with those from healthy controls.
Expression of the protein tyrosine kinases Lyn, Fgr and Yes1
was increased in HMC-1.2 cells as compared with the
ontogenetically related HL60 cells. Differences in gene
regulation in HMC-1.2 cells after treatment with the
1,4-benzodiazepines clonazepam, flunitrazepam and
4-chlorodiazepam suggested that signaling and gene
expression induced by clonazepam was similar to that of
flunitrazepam but different from that of 4-chlorodiazepam.
This conclusion is supported by the results of the pathway
analysis.A novel type of GABA(A) receptors on mast cells
appears to be involved in the inhibition of mast cell
activity by 1,4-benzodiazepines. These receptors seem to be
composed without γ subunits suggesting unique
pharmacological properties. An action at Src-kinases, or at
TSPO located in the plasma membrane may also be involved.},
