Application

Bisindolylmaleimide X hydrochloride has been used as a protein kinase C (PKC) inhibitor:
  • in chemotaxis assays
  • to inhibit protein kinase C and to study its effects on the expression of EGR1, NAB2, ZEBRA, and Rta
  • in the culture to study its effects on the expression of the kinase-insert domain-containing receptor (KDR)-B1, protein kinase Cθ (PKCθ)-M1a or Abl-HTa and on cell yield in baculovirus (BV)-infected insect cells

Biochem/physiol Actions

Bisindolylmaleimide X hydrochloride/Ro 31-8425, a strong and selective protein kinase C (PKC) inhibitor, can reduce the superoxide burst caused by various agonists in neutrophils. It can suppress the responses induced by cell surface receptors and phorbol esters in T cells. In humans, Ro 31-8425 can prevent neutrophil PKC in vitro with an IC50 of 5nM.

Intravital imaging has revealed that T cells change their migratory behavior during physiological activation inside lymphoid tissue. Yet, it remains less well investigated how the intrinsic migratory capacity of activated T cells is regulated by chemokine receptor levels or other

Previous studies implicating a role for protein kinase C (PKC) in mediating stimulation of cellular responses by physiological agonists have relied on use of non-specific inhibitors or direct stimulation of PKC by phorbol esters. However, much of this evidence is

The Epstein-Barr virus (EBV) lytic activator genes bzlf1 and brlf1 are conventionally referred to as immediate-early (IE) genes. However, previous studies showed that the earliest expression of these genes was blocked by cycloheximide when the EBV lytic cycle was induced

As exemplified by three cases, we show that the addition of a small molecular weight inhibitor to the culture of Baculovirus-infected insect cells can dramatically improve the expression of a recombinant kinase. The expression of the tyrosine kinase KDR was
