Abstract:
The invention relates to a process for quantitative determination of CD95 ligand, comprising the following steps: (a) isolation of total RNA from cells; (b) transcription of total RNA from (a) into cDNA by reverse transcription and; (c) amplification of cDNA from (b) and a CD95 ligand competitor fragment by CD95 ligand specific primers in a PCR reaction. The process is also suitable for determining the extent and/or course of apoptosis.
Abstract:
Described are pharmaceutical compositions containing a caspase-8 and/or caspase-9 protein and/or (a) DNA sequence(s) encoding a caspase-8 and/or caspase-9 protein and a suitable pharmaceutical carrier. Said compositions are useful for restoring apoptosis sensitivity of glucorticoid-induced resistance of carcinoma cells towards cytotoxic therapy.
Abstract:
The invention relates to a process for determining the activity, in particular cytostatic activity, of drugs. Said process comprises the following steps: (a) incubation of the drugs with cells, and; (b) detecting the extent of apoptosis which is caused by the CD95/CD95 ligand system.
Abstract:
The invention relates to a method for measuring the JNK/SAPK activity which is based on the implemation of a kinase reaction with JNK/SAPKs which are obtained from a cell lysate and preferably isolated by immune precipitation in the presence of ATP and GST transcription factors (preferably: GST-c-Jun), and subsequently measuring the amount of phosphorylate GST transcription factors (preferably: p-GST-c-Jun) according to the specific binding of an anti-p-GST transcription factor antibody(preferably: anti-p-GST-c-Jun-antibody).
