Meiotic And Mitotic Phenotypes Conferred By The Blm1-1 Mutation In Saccharomyces Cerevisiae And Msh4 Suppression Of The Bleomycin Hypersusceptibility, Georgia Anyatonwu, Ediberto Garcia, Ajay Pramanik, Marie Powell, Carol Wood Moore Jan 2003

Meiotic And Mitotic Phenotypes Conferred By The Blm1-1 Mutation In Saccharomyces Cerevisiae And Msh4 Suppression Of The Bleomycin Hypersusceptibility, Georgia Anyatonwu, Ediberto Garcia, Ajay Pramanik, Marie Powell, Carol Wood Moore

Publications and Research

Oxidative damage can lead to a number of diseases, and can be fatal. The blm1-1 mutation of Saccharomyces cerevisiae confers hypersusceptibility to lethal effects of the oxidative, anticancer and antifungal agent, bleomycin. For the current report, additional defects conferred by the mutation in meiosis and mitosis were investigated. The viability of spores produced during meiosis by homozygous normal BLM1/BLM1, heterozygous BLM1/blm1-1, and homozygous mutant blm1-1/blm1-1 diploid strains was studied and compared. Approximately 88% of the tetrads derived from homozygous blm1-1/blm1-1 mutant diploid cells only produced one or two viable spores. In contrast, just one tetrad among ...


Up-Regulation Of Neuronal Calcium Sensor-1 (Ncs-1) In The Prefrontal Cortex Of Schizophrenic And Bipolar Patients, Phil Ok Koh, Ashiwel S. Undieh, Robert Levenson, Patricia S. Goldman-Rakic, Michael S. Lidow Jan 2003

Up-Regulation Of Neuronal Calcium Sensor-1 (Ncs-1) In The Prefrontal Cortex Of Schizophrenic And Bipolar Patients, Phil Ok Koh, Ashiwel S. Undieh, Robert Levenson, Patricia S. Goldman-Rakic, Michael S. Lidow

The delineation of dopamine dysfunction in the mentally ill has been a long-standing quest of biological psychiatry. The present study focuses on a recently recognized group of dopamine receptor- interacting proteins as possible novel sites of dysfunction in schizophrenic and bipolar patients. We demonstrate that the dorsolateral prefrontal cortex in schizophrenia and bipolar cases from the Stanley Foundation Neuropathology Consortium display significantly elevated levels of the D2 dopamine receptor desensitization regulatory protein, neuronal calcium sensor-1. These levels of neuronal calcium sensor-1 were not influenced by age, gender, hemisphere, cause of death, postmortem period, alcohol consumption, or antipsychotic and mood stabilizing ...

Infant Mortality After Takeovers In Wild Ethiopian Hamadryas Baboons, Larissa Swedell, Teklu Tesfaye Jan 2003

Infant Mortality After Takeovers In Wild Ethiopian Hamadryas Baboons, Larissa Swedell, Teklu Tesfaye

Publications and Research

In this paper, we report the first observational evidence of infanticide in wild hamadryas baboons. The study group inhabits the lowlands of the northern Rift Valley in Ethiopia and has been under observation for over 1200 hours, on and off, since October 1996. Here we report observations from August and September 2002 of the consequences of two takeovers of known females with black infants. After the first takeover, the respective infant disappeared and was presumed dead within eleven days of the takeover. After the second takeover, the infant incurred repeated severe aggression from its mother’s new leader male and ...
