The anti-malarial drug artesunate causes cell cycle arrest and apoptosis of triple-nega... - 0 views

  •  
    ART inhibited breast cancer cell proliferation via a reactive oxygen species (ROS)-dependent G2/M arrest and ROS-independent G1 arrest. ART-treated MDA-MB-468 and SK-BR-3 cells also experienced apoptotic cell death, which was both ROS- and iron-dependent. ART-induced oxidative stress caused the loss of mitochondrial outer membrane integrity and damage to the cellular DNA of MDA-MB-468 and SK-BR-3 cells.

Intravenously administered vitamin C as cancer therapy: three cases - 0 views

  • peak plasma concentrations obtained intravenously are estimated to reach 14 000 μmol/L, and concentrations above 2000 μmol/L may persist for several hours
  • Emerging in vitro data show that extracellular ascorbic acid selectively kills some cancer but no normal cells by generating hydrogen peroxide
  • Death is mediated exclusively by extracellular ascorbate, at pharmacologic concentrations that can be achieved only by intravenous administration
  • ...6 more annotations...
  • Vitamin C may serve as a pro-drug for hydrogen peroxide delivery to extravascular tissues, but without the presence of hydrogen peroxide in blood
  • not all cancer cells were killed by ascorbic acid in vitro
  • Intravascular hemolysis was reported after massive vitamin C administration in people with glucose-6-phosphate dehydrogenase deficiency
  • Administration of high-dose vitamin C to patients with systemic iron overload may increase iron absorption and represents a contraindication
  • Ascorbic acid is metabolized to oxalate, and 2 cases of acute oxalate nephropathy were reported in patients with pre-existing renal insufficiency given massive intravenous doses of vitamin C
  • Rare cases of acute tumour hemorrhage and necrosis were reported in patients with advanced cancer within a few days of starting high-dose intravenous vitamin C therapy, although this was not independently verified by pathologic review
  •  
    IV vitamin C associated with prolonged survival in 3 patients with different cancers.  Peak serum levels reached 14,000 micromol/L, which levels above the 1,000 micro mol/L (cancer cell cytotoxic threshold) were maintained for hours

Nonantibiotic Effects of Fluoroquinolones in Mammalian Cells - 0 views

  •  
    New study suggests global epigenetics is the cause behind fluoroquinolone mechanism of the Tendinopathies.  Specifically, they suggest that Iron chelation by the fluoroquinolones supresses the expression of P4HA1 and LH1 to lead to weakend collagen.  They also described decreased epigenetic changes in collagen hydroxylation and suppression of HIF-1alpha as mechanisms contributing to the tendinopathies as well.

Lipid Peroxidation: Production, Metabolism, and Signaling Mechanisms of Malondialdehyde... - 0 views

  • Hydroxyl radicals cause oxidative damage to cells because they unspecifically attack biomolecules [22] located less than a few nanometres from its site of generation and are involved in cellular disorders such as neurodegeneration [23, 24], cardiovascular disease [25], and cancer [26, 27].
  • It is generally assumed that in biological systems is formed through redox cycling by Fenton reaction, where free iron (Fe2+) reacts with hydrogen peroxide (H2O2) and the Haber-Weiss reaction that results in the production of Fe2+ when superoxide reacts with ferric iron (Fe3+)
  • other transition-metal including Cu, Ni, Co, and V can be responsible for formation in living cells
  • ...20 more annotations...
  • The hydroperoxyl radical () plays an important role in the chemistry of lipid peroxidation
  • The is a much stronger oxidant than superoxide anion-radical
  • Lipid peroxidation can be described generally as a process under which oxidants such as free radicals or nonradical species attack lipids containing carbon-carbon double bond(s), especially polyunsaturated fatty acids (PUFAs) that involve hydrogen abstraction from a carbon, with oxygen insertion resulting in lipid peroxyl radicals and hydroperoxides as described previously
  • under medium or high lipid peroxidation rates (toxic conditions) the extent of oxidative damage overwhelms repair capacity, and the cells induce apoptosis or necrosis programmed cell death
  • The overall process of lipid peroxidation consists of three steps: initiation, propagation, and termination
  • Once lipid peroxidation is initiated, a propagation of chain reactions will take place until termination products are produced.
  • The main primary products of lipid peroxidation are lipid hydroperoxides (LOOH)
  • Among the many different aldehydes which can be formed as secondary products during lipid peroxidation, malondialdehyde (MDA), propanal, hexanal, and 4-hydroxynonenal (4-HNE) have been extensively studied
  • MDA has been widely used for many years as a convenient biomarker for lipid peroxidation of omega-3 and omega-6 fatty acids because of its facile reaction with thiobarbituric acid (TBA)
  • MDA is one of the most popular and reliable markers that determine oxidative stress in clinical situations [53], and due to MDA’s high reactivity and toxicity underlying the fact that this molecule is very relevant to biomedical research community
  • 4-HNE is considered as “second toxic messengers of free radicals,” and also as “one of the most physiologically active lipid peroxides,” “one of major generators of oxidative stress,” “a chemotactic aldehydic end-product of lipid peroxidation,” and a “major lipid peroxidation product”
  • MDA is an end-product generated by decomposition of arachidonic acid and larger PUFAs
  • Identifying in vivo MDA production and its role in biology is important as indicated by the extensive literature on the compound (over 15 800 articles in the PubMed database using the keyword “malondialdehyde lipid peroxidation” in December 2013)
  • MDA reactivity is pH-dependent
  • When pH decreases MDA exists as beta-hydroxyacrolein and its reactivity increases
  • MAA adducts are shown to be highly immunogenic [177–181]. MDA adducts are biologically important because they can participate in secondary deleterious reactions (e.g., crosslinking) by promoting intramolecular or intermolecular protein/DNA crosslinking that may induce profound alteration in the biochemical properties of biomolecules and accumulate during aging and in chronic diseases
  • MDA is an important contributor to DNA damage and mutation
  • This MDA-induced DNA alteration may contribute significantly to cancer and other genetic diseases.
  • Dietary intake of certain antioxidants such as vitamins was associated with reduced levels of markers of DNA oxidation (M1dG and 8-oxodG) measured in peripheral white blood cells of healthy subjects, which could contribute to the protective role of vitamins on cancer risk
  • 4-HNE is an extraordinarily reactive compound

Transdermal testosterone replacement therapy in men - 0 views

  • a recent study has suggested that it may sometimes be inaccurate because of abnormal fluctuation of other circulating androgens
    • Nathan Goodyear
       
      The authors are referencing the increase in the suggestions to use other testing techniques i.e. saliva.
  • Testosterone therapy can inhibit hepcidin transcription and is associated with increased iron incorporation into red blood cells and increased erythropoietin concentrations
  • Transdermal TRT has a more favorable adverse effect profile when compared to buccal testosterone formulations
  • ...13 more annotations...
  • Approximately 0.3% of testosterone is converted into estradiol by aromatase (CYP19A1)
  • the recommendation for injectable testosterone esters is to check the serum concentration midway between injections
  • it is recommended for serum testosterone to be evaluated 3 to 12 hours after application of the transdermal patch
  • testosterone concentrations should be checked 2–3 months after initiation of therapy and after adjusting the dose
  • a study from 1989 utilizing testosterone transdermally containing 5, 10, or 15 mg of testosterone showed that peak concentrations of testosterone were achieved 3 to 8 hours after scrotal application in hypogonadal men
  • It is used for many medications and has the advantage of high bioavailability, absence of hepatic first pass metabolism, increased therapeutic efficacy, and steadiness of plasma concentrations of the drug
  • evaluate serum testosterone at the end of the dosing interval for testosterone pellets
  • increased amount of fat leads to increased extragonadal aromatase activity, resulting in increased concentrations of estradiol. High circulating concentrations of estradiol down regulate the HPG axis and decrease the amount of circulating testosterone
  • Up to 80% of plasma estradiol originates from aromatization of testosterone and less than 20% of estradiol in the circulation is secreted by the testes
  • A PSA concentration, digital rectal examination, and hematocrit should be performed at baseline and at 3 months, 6 months, then yearly after TRT is initiated.
  • measure serum testosterone any time after the patient has been on treatment with gel for at least 1 week
  • If the hematocrit rises above 54%, treatment should be discontinued
  • elderly men having higher estradiol serum concentrations than postmenopausal women
