A metastatic rat mammary carcinoma cell line, BC1, contains cells that have retained epithelial differentiation characteristics and metaplastic cells that have undergone an epithelial-mesenchymal transition. These two subpopulations cooperate to degrade collagen. We have used novel PCR assays to quantitate, for the first time, absolute levels of the mRNAs encoding matrix metalloproteinases (MMP...
The cytochrome bc1 complex (cyt bc1) is the third component of the mitochondrial electron transport chain and is the target of several potent antimalarial compounds, including the naphthoquinone atovaquone (ATV) and the 4(1H)-quinolone ELQ-300. Mechanistically, cyt bc1 facilitates the transfer of electrons from ubiquinol to cytochrome c and contains both oxidative (Qo) and reductive (Qi) cataly...
ID elements are short interspersed elements (SINEs) found in high copy number in many rodent genomes. BC1 RNA, an ID-related transcript, is derived from the single copy BC1 RNA gene. The BC1 RNA gene has been shown to be a master gene for ID element amplification in rodent genomes. ID elements are dispersed through a process termed retroposition. The retroposition process involves a number of p...
This study provides a first attempt from a toxicological perspective to put forward, in general terms and explanations, the toxicity series of Cd(II), Cu(II) and Zn(II) to Thiobacillus thiooxidans BC1. Sulphur oxidation and sulphuric acid production are strongly related to microbial growth at pH less than 4. Dose–response analysis on chronic and acute toxicity (e.g. EC20, median effective dose ...
Cotton leaf curl virus disease (CLCuD) is an important constraint to cotton production. The resistance of G. arboreum to this devastating disease is well documented. In the present investigation, we explored the possibility of transferring genes for resistance to CLCuD from G. arboreum (2n = 26) cv 15-Mollisoni into G. hirsutum (2n = 52) cv CRSM-38 through conventional breeding. We investigated...
BACKGROUND Surface enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF) is an approach to biomarker discovery that combines chromatography and mass spectrometry. We aimed to consider the efficacy of Bc1, Bc2, and Bc3 serum biomarkers on early detection of breast cancer (BC) in this study. STUDY DESIGN In this prospective study, 91 patients who were admitted to our...
Excessive, long-term chemical fertilizer application adversely affects soil quality and maize yield. The combined of biochar with can increase yield improve fertility. A four-year field experiment was conducted to determine physio-biochemical properties under a soybean–maize rotation in the black soils Northeast China. There were five treatments, including no fertilization (CK), (NPK), + (15.75...
ID elements comprise a rodent SINE (short interspersed DNA repetitive element) family that has amplified by retroposition of a few master genes. In order to understand the important factors of SINE amplification, we investigated the transcription of rat ID elements. Three different size classes of ID transcripts, BC1, BC2 and T3, have been detected in various rat tissues, including brain and te...
Dendritic localization of mRNA/RNA involves interaction of cis-elements and trans-factors. Small, non-protein coding dendritic BC1 RNA is thought to regulate translation in dendritic microdomains. Following microinjections into cultured cells, BC1 RNA fused to larger mRNAs appeared to impart transport competence to these chimeras, and its 5' ID region was proposed as the cis-acting dendritic ta...
