In response to DNA damage, cells activate checkpoint pathways that prevent cell cycle progression. In fission yeast and mammals, mitotic arrest in response to DNA damage requires inhibitory Cdk phosphorylation regulated by Chk1. This study indicates that Chk1 is required for function of the DNA damage checkpoint in Saccharomyces cerevisiae but acts through(More)
We have isolated a Drosophila mutant, named pumpless, which is defective in food intake and growth at the larval stage. pumpless larvae can initially feed normally upon hatching. However, during late first instar stage, they fail to pump the food from the pharynx into the esophagus and concurrently begin moving away from the food source. Although pumpless(More)
Drosophila encodes five muscle and one cytoskeletal isoform of the actin-binding protein tropomyosin. We have identified a lack-of-function mutation in the cytoskeletal isoform (cTmII). Zygotic mutant embryos show a defect in head morphogenesis, while embryos lacking maternal cTmII are defective in germ cell formation but otherwise give rise to viable(More)
An isoform of the estrogen receptor messenger RNA (ER-mRNA) was identified in RNA from the brain of lizards and rats. Poly(A)+ RNA from brain and uteri was reverse transcribed using gene-specific primer for the ER. The resulting complementary DNA was amplified in a polymerase chain reaction followed by cloning and sequencing of the amplified products. This(More)
The motivational characteristics of psychotherapy inpatients should be of crucial importance for treatment effectiveness. In the present study on 219 patients from two psychosomatic-psychotherapeutic treatment centers, four dimensions of motivation for psychotherapy (illness experience; lay etiology; treatment expectations; openness to psychotherapy) were(More)
