    Notes: [Auszug] White blood cell DNA from cancer patients and DNA from tumours and tumour-derived cell lines frequently demonstrated allelic restriction fragments of the Harvey ras oncogene locus not found in the unaffected population. The presence of such unusual alleles may be linked to susceptibility to ...

    Notes: Summary In this phase II trial, twenty patients with advanced, measurable melanoma from ECOG institutions were treated with esorubicin 30 mg/m2 iv every three weeks. Doses were escalated or reduced based on nadir counts. The dose limiting toxicity was leukopenia with no significant thrombocytopenia or anemia. Other toxicities were mild. One patient had skin necrosis with extravasation. Two patients with soft tissue disease had partial remissions and were treated with 9 and 17 courses. One patient was stable for 8 courses. No cardiac toxicity was seen in three patients receiving more than 150 mg/m2. The response rate was 10% (90% CI = 2 to 30%). Low level activity was seen, but it is unlikely that this drug has sufficient activity to warrant further development in melanoma.

    Notes: At the National Cancer Institute, Division of Cancer Prevention and Control, the Chemoprevention Branch and Agent Development Committee develop strategies for efficiently identifying, procuring, and advancing the most promising drugs into clinical trials. Scientific expertise is applied at each phase of development to critically review the testing methods and results, and to establish and apply criteria for evaluating the agents for further development. The Clinical Development Plan, prepared by the Chemoprevention Branch and the Agent Development Committee, is a summary of the status of the agent regarding evidence for safety and chemopreventive efficacy in preclinical and clinical studies. It also contains the strategy for further development of the drug that addresses pharmacodynamics, drug effect measurements, intermediate biomarkers for monitoring efficacy, toxicity, supply and formulation, regulatory approval, and proposed clinical trials. Sixteen Clinical Development Plans are presented here: N-acetyl-l-cysteine (NAC), aspirin, calcium, β-carotene, 2-difluoromethylornithine (DFMO), DHEA analog 8354, 18β-glycyrrhetinic acid, N-(4-hydroxyphenyl)retinamide (4-HPR), ibuprofen, oltipraz, piroxicam, Proscar®, sulindac, tamoxifen, vitamin D3 and analogs and vitamin E. The objective of publishing these plans is to stimulate interest and thinking among the scientific community on the prospects for developing chemopreventive drugs. 1994 Wiley-Liss, Inc.This article is a US Government work and, as such, is in the public domain in the United States of America.

    Notes: This is the second publication of Clinical Development Plans from the National Cancer Institute, Division of Cancer Prevention and Control, Chemoprevention Branch and Agent Development Committee. The Clinical Development Plans summarize the status of promising chemopreventive agents regarding evidence for safety and chemopreventive efficacy in preclinical and clinical studies. They also contain the strategy for further development of these drugs, addressing pharmacodynamics, drug effect measurements, intermediate biomarkers for monitoring efficacy, toxicity, supply and formulation, regulatory approval, and proposed clinical trials. Sixteen new Clinical Development Plans are presented here: curcumin, dehydroepiandrosterone, folic acid, genistein, indole-3-carbinol, perillyl alcohol, phenethyl isothiocyanate, 9-cis-retinoic acid, 13-cis-retinoic acid, l-selenomethionine and 1,4-phenylenebis(methylene)selenocyanate, sulindac sulfone, tea, ursodiol, vitamin A, and (+)-vorozole. The objective of publishing these plans is to stimulate interest and thinking among the scientific community on the prospects for developing these and future generations of chemopreventive drugs. © 1997 Wiley-Liss, Inc.

    Notes: The polymorphic restriction fragments of the human Ha-ras locus, produced by the variable tandem repetition (VTR) of a short consensus sequence, fall into three classes based on allelic frequencies. Alleles of the “rare” class (individual frequencies 〈 0.5%) have been detected only in white blood cell and tumor DNA of cancer patients. This phenomenon is independent of ethnic origin. No significant association of rare alleles with cancer patients has been demonstrated at an independent tandem repeat locus, VTR4.1. The results suggest that the Ha-ras restriction fragment length polymorphism is useful in cancer risk assessment.

    Description / Table of Contents: α-Keratose, eine alkalilösliche Fraktion der mit Peressigsäure oxidierten Wolle mit niedrigem Schwefelgehalt, wurde unter kontrollierten Bedingungen teilweise mit Säure hydrolysiert. Das Gemisch von Peptiden mit niedrigem Molekulargewicht wurde in zwei Fraktionen aufgetrennt. Die an Cysteinsäure reiche Fraktion wurde einer möglichst quantitativen Untersuchung unterworfen. Es hat sich gezeigt, daß sie 63% des Cysteinsäuregehaltes (Cya) der α-Keratose enthält, der peptidartig gebunden ist. Dieses Material wurde weiter fraktioniert; die Strukturen einer Reihe der vorhandenen Cysteinsäurepeptide wurden abgeleitet. Die Menge jedes einzelnen Peptids, das in α-Keratose anwesend ist, wurde berechnet. Die meistverbreiteten Dipeptid-Sequenzen der Cysteinsäure, die in α-Keratose festgestellt wurden, sind (in absteigender Folge) Ser-Cya, Cya-Cya, Cya-Gly, Cya-Pro, Cya-Val, Cya-Glu, Gly-Cya. Die Ergebnisse wurden mit früheren Befunden für die Fraktion mit hohem Schwefelgehalt (gamma;-Keratose) verglichen. Während die Umgebung des Halbcysteins in α-Keratose unterschiedlicher ist als in γ-Keratose, ist sie doch vorwiegend nichthelical.
    Notes: α-Keratose, an alkali-soluble fraction of peracetic acid oxidised wool of low sulphur content has been partially hydrolysed under controlled conditions with acid. The mixture of low molecular weight peptides has been fractionated into two fractions. The cysteic acid rich fraction has been studied in as quantitative a manner as possible. It has been shown to contain 63% of the cysteic acid (Cya) content of α-keratose bound in peptides. This material has been further fractionated and the structures of a number of cysteic acid peptides present have been deduced. The amounts of each present in α-keratose have been calculated. The most common two-residue sequences of cysteic acid identified in α-keratose are (in descending order) Ser-Cya, Cya-Cya, Cya-Gly, Cya-Pro, Cya-Val, Cya-Glu, Gly-Cya. The results have been compared with previous findings for the high sulphur fraction (γ-keratose). Whilst the environment of half cystine in α-keratose is more varied than in γ-keratose, it is still predominantly non-helical.
