Inhibition of telomerase activity correlates with a decrease in the RNA component of telomerase during differentiation

In most normal somatic cells the telomeres of human chromosomes shorten with each cell division because of low expression or lack of telomerase activity. Telomerase, a ribonucleoprotein that synthesizes telomeric DNA onto chromosomal ends, is reactivated or upregulated in tumor cells and maintains the stability of telomere length. We previously showed that treatment of HL60 leukemia cells with differentiation-inducing agents resulted in inhibition of telomerase activity. In the present study, we found that the decrease in telomerase activity did not temporally correlate with the expression of a differentiation marker, CD11b, on the cell surface. Mixing of protein extracts from telomerase-negative differentiated HL60 cells with those from parental HL60 cells did not result in inhibition of telomerase activity, suggesting that a diffusible cellular telomerase inhibitor was not produced in the differentiated cells. However, a decrease in telomerase activity correlated with a selective decrease of telomerase RNA expression, a decrease in the levels of total cellular RNA, and an increase in cells at G(0) phase.     

Pharmacodynamic Analysis of Analgesic Clinical Trials Using Empirical Methods

Data from analgesic clinical trials have characteristics such as ordered categorical longitudinal responses with repeated measures, delay of effect with respect to analgesic plasma concentration, and right-hand censoring of response due to remedication. In order to determine the concentration-effect relationship of such data, we propose convolving an empirical function for plasma concentration, in the form of broken lines which connect each pair of neighboring observations, with a monoexponential function, to generate effect site concentration Effect site concentration and time are used, simultaneously, as independent variables in the fit of the model for the logit of the probability of having a specific pain relief (PR) score at each time point pre-remedication, via maximum likelihood. Using corresponding effect site concentration, the probabilities of having specific PR scores post-remedication are predicted via the concentration-response relationship established. The overall (pre- and post-remedication) predictions and corresponding standard errors for the responses are then estimated. Inference of the PR scoring, using a posterior method, is proposed. An illustration using real data is used to demonstrate these methods.
