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...

Despite the potentially important roles of untranslated RNAs in cellular form or function, genes encoding such RNAs have until now received surprisingly little attention. One such gene encodes BC1 RNA, a small non-mRNA that is delivered to dendritic microdomains in neurons. We have now eliminated the BC1 RNA gene in mice. Three independent founder lines were established from separate embryonic ...

NrrF is a small regulatory RNA of the human pathogen Neisseria meningitidis. NrrF was previously shown to repress succinate dehydrogenase (sdhCDAB) under control of the ferric uptake regulator (Fur). Here, we provide evidence that cytochrome bc1 , encoded by the polycistronic mRNA petABC, is a NrrF target as well. We demonstrated differential expression of cytochrome bc1 comparing wild-type men...

BACKGROUND Clear cell renal cell carcinoma (ccRCC) is the most frequently encountered tumor in the adult kidney. Many factors are known to take part in the development and progression of this tumor. Nuclear factor kappa B (NF-kappaB) is a family of the genes that includes five members acting in events such as inflammation and apoptosis. In this study, the role of NF-kappaB (p50 subunit) in ccRC...

BACKGROUND Binding of two 9-O-(ω-amino) alkyl ether berberine analogs BC1 and BC2 to the RNA triplex poly(U)(•)poly(A)(*)poly(U) was studied by various biophysical techniques. METHODOLOGY/PRINCIPAL FINDINGS Berberine analogs bind to the RNA triplex non-cooperatively. The affinity of binding was remarkably high by about 5 and 15 times, respectively, for BC1 and BC2 compared to berberine. The s...

Burkholderia sp. strain BC1, a soil bacterium, isolated from a naphthalene balls manufacturing waste disposal site, is capable of utilizing 2-hydroxy-1-naphthoic acid (2H1NA) and naphthalene individually as the sole source of carbon and energy. To deduce the pathway for degradation of 2H1NA, metabolites isolated from resting cell culture were identified by a combination of chromatographic and s...

Erianthus arundinaceus is a valuable source of agronomic traits for sugarcane improvement such as ratoonability, biomass, vigor, tolerance to drought and water logging, as well as resistance to pests and disease. To investigate the introgression of the E. arundinaceus genome into sugarcane, five intergeneric F1 hybrids between S. officinarum and E. arundinaceus and 13 of their BC1 progeny were ...
