I have also tried Promegas RNasin with MMLV (ClonTech) for generating cDNA to be used in differential display PCR and it did not work. I have also tried cDNA synthesis without RNase inhibitor and the DDRT-PCR works well. Recently i tried cDNA synthesis with an RNase inhibitor and MMLV, both from ClonTech (1st Strand Synthesis Kit), and DDRT-PCT. It worked well and i got more larger PCR products. So it seems that if your RNA is of a high quality, you can leave out the RNase inhibitor, but you do get better results if it is included. It would seem that certain RNase inhibitors work well with some reverse transcriptases. Best thing is to find a combination of inhibtor and enzyme that work well together and stick to it. (PS. it is possible that Promegas RNasin works well with their reverse transcriptase) (These are only my views) On 31 Aug 1995 mhughes at mbcf.stjude.org wrote: , In article ,42079o$kus at cronkite.seas.gwu.edu,, sullivan at gwis2.circ.gwu.edu (Steven Sullivan) writes: , , In the ...

TY - JOUR. T1 - A structural basis of the interactions between leucine-rich repeats and protein ligands. AU - Kobe, Bostjan. AU - Deisenhofer, Johann. PY - 1995/1/1. Y1 - 1995/1/1. N2 - THE leucine-rich repeat is a recently characterized structural motif1 used in molecular recognition processes as diverse as signal transduction, cell adhesion, cell development, DNA repair and RNA processing2. We present here the crystal structure at 2.5 Å resolution of the complex between ribonuclease A and ribonculease inhibitor, a protein built entirely of leucine-rich repeats. The unusual non-globular structure of ribonuclease inhibitor, its solvent-exposed parallel β-sheet and the conformational flexibility of the structure are used in the interaction; they appear to be the principal reasons for the effectiveness of leucine-rich repeats as protein-binding motifs. The structure can serve as a model for the interactions of other proteins containing leucine-rich repeats with their ligands.. AB - THE ...

Overview. DNase I from bovine pancreas is a glycoprotein of Mr 37000. A special procedure is used to remove RNases from the DNase preparation. DNase I is a DNA-specific endonuclease that hydrolyzes ds or ssDNA to a mixture of oligo and mononucleotides. The enzyme requires divalent cations for maximal activity. The specificity of the reaction depends on the nature of the cations. In the presence of Mg2+ DNase I cause nicks in dsDNA, while in the presence of Mn2+ the enzyme produces double-stranded breaks.. Suggested Method for the Removal of DNA for RT-PCR. 10 x reaction buffer: 200 mM Tris-HCl, pH 8.3 500 mM KCl 10 mM MnCl2 recommended to add 20 U Protector RNase Inhibitor ...
Validity of biobank studies on hormone associated cancers depend on the extent the sample preservation is affecting the hormone measurements. We investigated the effect of long-term storage (up to 22 years) on immunoassay measurements of three groups of hormones and associated proteins: sex-steroids [estradiol, progesterone, testosterone, dihydroepiandrosterone sulphate (DHEAS), sex hormone-binding globulin (SHBG)], pregnancy-specific hormones [human chorionic gonadotropin (hCG), placental growth hormone (pGH), alpha-fetoprotein (AFP)], and insulin-like growth factor (IGF) family hormones exploiting the world largest serum bank, the Finnish Maternity Cohort (FMC). Hormones of interest were analyzed in a random sample of 154 Finnish women in the median age (29.5 years, range 25 to 34 years) of their first pregnancy with serum samples drawn during the first trimester. All hormone measurements were performed using commercial enzyme-linked- or radio-immunoassays. Storage time did not correlate with ...
RefSeq Summary (NM_002059): The protein encoded by this gene is a member of the somatotropin/prolactin family of hormones which play an important role in growth control. The gene, along with four other related genes, is located at the growth hormone locus on chromosome 17 where they are interspersed in the same transcriptional orientation; an arrangement which is thought to have evolved by a series of gene duplications. The five genes share a remarkably high degree of sequence identity. Alternative splicing generates additional isoforms of each of the five growth hormones, leading to further diversity and potential for specialization. As in the case of its pituitary counterpart, growth hormone 1, the predominant isoform of this particular family member shows similar somatogenic activity, with reduced lactogenic activity. Mutations in this gene lead to placental growth hormone/lactogen deficiency. [provided by RefSeq, Jul 2008 ...
Placental lactogen, also called chorionic somatomammotropin, is a polypeptide placental hormone, part of the somatotropin family. Its structure and function is similar to that of growth hormone. It modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus. For information on the human form, see human placental lactogen. Placental lactogen I and II were identified as prolactin-like molecules that can bind to prolactin receptor with high affinity and mimic the actions of prolactin. These hormones can contribute to lactogenesis, luteal maintenance and progesterone production (in rats) during the later stages of gestation. Placental lactogen I may be important in stimulating mammary cell proliferation and in stimulating some of the adaptations of the maternal lipid and carbohydrate metabolism. ...
Ribosomal proteins (RP) regulate specific gene expression by selectively translating subsets of mRNAs. Indeed, in Diamond-Blackfan anemia and 5q- syndrome, mutations in RP genes lead to a specific defect in erythroid gene translation and cause anemia. Little is known about the molecular mechanisms of selective mRNA translation and involvement of ribosomal-associated factors in this process. Ribonuclease inhibitor 1 (RNH1) is a ubiquitously expressed protein that binds to and inhibits pancreatic-type ribonucleases. Here, we report that RNH1 binds to ribosomes and regulates erythropoiesis by controlling translation of the erythroid transcription factor GATA1. Rnh1-deficient mice die between embryonic days E8.5 and E10 due to impaired production of mature erythroid cells from progenitor cells. In Rnh1-deficient embryos, mRNA levels of Gata1 are normal, but GATA1 protein levels are decreased. At the molecular level, we found that RNH1 binds to the 40S subunit of ribosomes and facilitates polysome ...

1B1E: Refined crystal structures of native human angiogenin and two active site variants: implications for the unique functional properties of an enzyme involved in neovascularisation during tumour growth.
The affinity of RI for ribonucleases is among the highest for any protein-protein interaction; the dissociation constant of the RI-RNase A complex is in the femtomolar (fM) range under physiological conditions while that for the RI-angiogenin complex is less than 1 fM. Despite this high affinity, RI is able to bind a wide variety of RNases A despite their relatively low sequence identity. Both biochemical studies and crystallographic structures of RI-RNase A complexes suggest that the interaction is governed largely by electrostatic interactions, but also involves substantial buried surface area.[3][4] RIs affinity for ribonucleases is important, since many ribonucleases have cytotoxic and cytostatic effects that correlate well with ability to bind RI.[5] Mammalian RIs are unable to bind certain pancreatic ribonuclease family members from other species. In particular, amphibian RNases, such ranpirnase and amphinase from the Northern leopard frog, escape mammalian RI and have been noted to have ...
Inclusion of aurintricarboxylic acid (ATA) in extraction buffers for the isolation of RNA from animal tissues resulted in high yields (0.5-2.0 mg/g of tissue) of undegraded material as judged by agarose-gel-electrophoretic analyses and Northern-blotting experiments. However, ATA bound to nucleic acids, forming stable complexes, and so we have established methods for spectrophotometric quantification of RNA in these coloured complexes, and for easy removal of sufficient ATA to leave RNA in a consistently hybridizable condition at the end of a purification. The use and subsequent removal of ATA was straightforward and gave satisfactory results for all rat tissues tested.. ...

In this book the contributors have compiled several aspects that should be considered in pregnancies with GD. The book is divided into two sections: (a) GD Patient Care and Considerations, and (b) Cell and Molecular Mechanisms Behind this Syndrome. In the first section (Chapter 1), Professor M.R. Begum (AKM Medical College, Dhaka, Bangladesh) proposes several management recommendations for a better comprehension of the diseases in pregnancy and its consequences. In this review, it is proposed that pregnancy progresses with changes in maternal carbohydrate occur and the placental hormones act as contrainsulin factor leading to insulin resistance with a final increase in insulin secretion. When this physiological compensation is inadequate, then GD develops. Unfortunately, we do not have tools for an early diagnosis of GD, or, even more importantly, a protocol that allows prevention of GD, but as soon as this syndrome is diagnosed or recognized management is required. GD ends in a sort of ...
How can enzyme-catalyzed RNA cleavage promote the growth of new blood vessels? The responsible enzyme-angiogenin-was the first substance shown to promote organogenesis (here, neovascularization). Its 1985 discovery at Harvard Medical School was lauded on the front page of the New York Times. Despite its importance, the mechanism by which a ribonuclease promotes cell proliferation was a mystery until we discovered that angiogenin catalyzes the cleavage of a particular phosphodiester bond in a nucleolar substrate: promoter-associated RNA (pRNA). That cleavage prevents the silencing of ribosomal DNA transcription by the nucleolar remodeling complex (NoRC). We also found that angiogenin is phosphorylated on key serine residues, enabling evasion of the ribonuclease inhibitor protein and passage to the nucleus. Thus, unlike canonical growth factors that deliver epigenetic information to DNA indirectly via receptor-mediated signal-transduction pathways, angiogenin is unique in conveying its ...
Ribonuclease activity in cell-free thymus homogenates was elevated for five strains of mice genetically predisposed toward leukemia or reticulum cell neoplasms (AKR, C58, PL, RF, and SJL). Such increased activity was directed against polyuridylic acid and was observed in 8-wk old mice, well before the onset of neoplastic transformation. Similarly, white blood cell ribonuclease activity was elevated in mice of the strains AKR, C2H/He, PL and RF. Statistical analysis indicated that such elevated activity in these strains related to their high incidence of spontaneous neoplastic disease. Elevated ribonuclease activity thus represents a new biochemical marker relating to the genetic propensity of some strains of mice to die prematurely of spontaneous neoplasia. ...
ProtoScript II First Strand cDNA Synthesis Kit features two optimized mixes, ProtoScript II Enzyme Mix and ProtoScript II Reaction Mix. The enzyme mix combines ProtoScript II Reverse Transcriptase and Murine RNase Inhibitor, while the reaction mix contains dNTPs and an optimized buffer. ProtoScript II Reverse Transcriptase is a recombinant M-MuLV reverse transcriptase with reduced RNase H activity and increased thermostability. It can be used to synthesize first strand cDNA at higher temperatures than the wild type M-MuLV. The enzyme is active up to 48°C, providing higher specificity and higher yield of cDNA. The kit also provides two optimized primers for reverse transcription and nuclease-free water. An anchored Oligo-dT primer [d(T)23VN] forces the primer to anneal to the beginning of the polyA tail. The optimized Random Primer Mix provides random and consistent priming sites covering the entire RNA templates including both mRNAs and non-polyadenylated RNAs.

Dr. Adibi: Prenatal exposure to phthalates in rodents can cause defects in male sexual development including a shorter distance between the anus and the genitalia (anogenital distance or AGD). Human studies have shown a correlation between higher prenatal phthalate urinary concentrations in the mother and shorter AGD in males. AGD in males is related to fertility and reproductive health over the lifetime. In females, AGD was associated with numbers of ovarian follicles. The role of the placenta has not been considered in these studies. A placental hormone called human chorionic gonadotropin (hCG) is essential for normal male development. Our previous research has shown that hCG expression by human placental cells is disrupted by phthalate concentrations equal to what we measured in maternal urine. The placenta secretes molecules early in pregnancy that might provide an opportunity to detect these effects in humans.. Medical Research: What are the main findings?. Dr. Adibi: In 350 pregnancies, we ...
Synaptoneurosomes were lysed by addition of Triton X-100 (final concentration, 1.2%), deoxycholate to 0.6%, cycloheximide to 100 μg/ml, in 100 mM Tris (pH 7.6) in the presence of RNase inhibitors. The lysates were layered over 1 M sucrose in a polysome buffer (RKB; 0.01 M Tris, pH 7.6/1.5 mM MgCl2/1 mM potassium acetate/2 mM 2-mercaptoethanol), and centrifuged at 400,000 × g for 11 min in a Beckman TL-100 ultracentrifuge. The resultant polysomal pellets were resuspended in 80 mM Tris (pH 8), 80 mM NaCl, 3 mM MgCl2, 1.2% Triton N-101 (RP; 24, 25).

During pregnancy, the placenta supplies a growing fetus with nutrients and water, as well as produces a variety of hormones to maintain the pregnancy. In early pregnancy, hormones can cause increased insulin secretion and decreased glucose produced by the liver, which can lead to hypoglycemia (low blood glucose levels). In later pregnancy, some of these hormones (estrogen, cortisol, and human placental lactogen) can have a blocking effect on insulin, a condition called insulin resistance.. As the placenta grows, more of these hormones are produced, and insulin resistance becomes greater. Normally, the pancreas is able to make additional insulin to overcome insulin resistance, but when the production of insulin is not enough to overcome the effect of the placental hormones, gestational diabetes results or there may be worsening of pregestational diabetes.. ...
