Expression Of G-Protein Inwardly Rectifying Potassium Channels (Girks) In Lung Cancer Cell Lines, Howard Plummer 3rd, Madhu Dhar, Maria Cekanova Ms, Rndr, Phd, Hildegard Schuller Aug 2005

Expression Of G-Protein Inwardly Rectifying Potassium Channels (Girks) In Lung Cancer Cell Lines, Howard Plummer 3rd, Madhu Dhar, Maria Cekanova Ms, Rndr, Phd, Hildegard Schuller

Maria Cekanova MS, RNDr, PhD

BACKGROUND: Previous data from our laboratory has indicated that there is a functional link between the beta-adrenergic receptor signaling pathway and the G-protein inwardly rectifying potassium channel (GIRK1) in human breast cancer cell lines. We wanted to determine if GIRK channels were expressed in lung cancers and if a similar link exists in lung cancer. METHODS: GIRK1-4 expression and levels were determined by reverse transcription polymerase chain reaction (RT-PCR) and real-time PCR. GIRK protein levels were determined by western blots and cell proliferation was determined by a 5-bromo-2'-deoxyuridine (BrdU) assay. RESULTS: GIRK1 mRNA was expressed in three of six small …


Inequalities In Neighbourhood Socioeconomic Characteristics: Potential Evidence-Base For Neighbourhood Health Planning., Agricola Odoi, R Wray, M Emo, S Birch, B Hutchison, J Eyles, T Abernathy Aug 2005

Inequalities In Neighbourhood Socioeconomic Characteristics: Potential Evidence-Base For Neighbourhood Health Planning., Agricola Odoi, R Wray, M Emo, S Birch, B Hutchison, J Eyles, T Abernathy

Agricola Odoi

BACKGROUND: Population health planning aims to improve the health of the entire population and to reduce health inequities among population groups. Socioeconomic factors are increasingly being recognized as major determinants of many aspects of health and causes of health inequities. Knowledge of socioeconomic characteristics of neighbourhoods is necessary to identify their unique health needs and enhance identification of socioeconomically disadvantaged populations. Careful integration of this knowledge into health planning activities is necessary to ensure that health planning and service provision are tailored to unique neighbourhood population health needs. In this study, we identify unique neighbourhood socioeconomic characteristics and classify the …


Two Forms Of The Large Tumor Suppressor Gene (Lats1) Protein Expressed In The Vertebrate Retina, Novrouz B. Akhmedov, Clyde K. Yamashita, Dai Tran, Natik I. Piri, Gustavo D. Aguirre, Debora B. Farber Mar 2005

Two Forms Of The Large Tumor Suppressor Gene (Lats1) Protein Expressed In The Vertebrate Retina, Novrouz B. Akhmedov, Clyde K. Yamashita, Dai Tran, Natik I. Piri, Gustavo D. Aguirre, Debora B. Farber

Gustavo D. Aguirre, VMD, PhD

The large tumor suppressor gene (Lats1) encodes a protein kinase that is highly conserved from fly to human, and plays a crucial role in the prevention of tumor formation by controlling mitosis progression. We have found that in addition to the previously isolated 7.5 kb long form of Lats1 (Lats1L) mRNA, a less abundant, shorter, 3.4 kb primary transcript (Lats1S) also is expressed in the vertebrate retina. Compared toLats1L, the sequence of Lats1S mRNA has a deletion of exons 6, 7, and 8 that corresponds to 792 bp …

Plant and animal karyotypes sometimes contain variable elements, that are referred to as additional or B-chromosomes. It is generally believed that B-chromosomes lack major genes and represent parasitic and selfish elements of a genome. Here we report, for the first time, the localization of a gene to B-chromosomes of mammals: red fox (Vulpes vulpes) and two subspecies of raccoon dog (Nyctereutes procyonoides). Identification of the proto-oncogene C-KIT on B-chromosomes of twoCanidae species that diverged from a common ancestor more than 12.5 million years ago argues against the current view of B-chromosomes. Analyses of fox B-chromosomal …
