Mutations in Escherichia Coli Induced by Chemical Agents [PDF]

open access: yes, 1947
For over two decades geneticists have been interested in the possibility of inducing mutations with chemicals. Particularly, it has been hoped that mutagenic compounds might be discovered which, through their specificity of action, would lead to some ...

MODIFICATION OF REPRODUCTIVE FUNCTION IN THE RAT BY 3-METHYLCHOLANTHRENE

open access: yesPharmacological Research, 1997
Repeated exposure of adult female Wistar rats to 3-methylcholanthrene (MC) (25 mg kg(-1) b.w., i.p., 2xwk, 1 mo) was associated with a significant increase in estrus cycle length. In addition, an increased frequency of females with constant diestrus and abnormal cycles was observed.

CT-2A neurospheres-derived high-grade glioma in mice: a new model to address tumor stem cells and immunosuppression

open access: yesBiology Open, 2019
Recently, several promising treatments for high-grade gliomas (HGGs) failed to provide significant benefit when translated from the preclinical setting to patients. Improving the animal models is fundamental to overcoming this translational gap.

Genomic rearrangements in mouse C3H/10T1/2 cells transformed by X-rays, UV-C, and 3-methylcholanthrene, detected by a DNA fingerprint assay[superscript 1] [PDF]

open access: yes, 1992
Genomic rearrangements occurring in C3H/10T1/2 cells transformed by X-rays were examined with a DNA fingerprint assay. Four multilocus and multiallele probes were employed (M, X, H10, and H16) that detect different families of minisatellite sequences ...

Pharmacokinetics of mirodenafil, a new erectogenic, and its metabolite, SK3541, in rats: involvement of CYP1A1/2, 2B1/2, 2D subfamily, and 3A1/2 for the metabolism of both mirodenafil and SK3541

open access: yesJournal of Pharmacy & Pharmaceutical Sciences, 2010
Purpose. This study was performed to find which types of hepatic CYP isoforms are responsible for the metabolism of mirodenafil (a new erectogenic) and one of its metabolite, SK3541, using various hepatic CYP inducers and inhibitors in rats.

Natural killer (NK) cells and their involvement in different types of cancer. Current status of clinical research [PDF]

open access: yes, 2017
Natural killer cells are the main agents of innate immunity. Since 1970, various studies have repeatedly confirmed their involvement in decreasing local tumor growth and also decreasing the risk of metastasis, due to their cytotoxic effects and also ...

Inhibition of liver methionine adenosyltransferase gene expression by 3-methylcolanthrene: protective effect of S-adenosylmethionine [PDF]

open access: yes, 2001
Methionine adenosyltransferase (MAT) is an essential enzyme that catalyzes the synthesis of S-adenosylmethionine (AdoMet), the most important biological methyl donor. Liver MAT I/III is the product of the MAT1A gene.

Activation of p53 as a causal step for atherosclerosis induced by polycyclic aromatic hydrocarbons [PDF]

open access: yes, 2006
This study was performed to prove our hypothesis that the metabolite(s) of polycyclic aromatic hydrocarbons (PAHs) caused the activation or phosphorylation of p53 via DNA damage to suppress the liver X receptor (LXR)-mediated signal transductions as a ...

Modulation of CYP1A1 by PKC Inhibitors and TPA Pre-Treatments in MH1C1 Rat Hepatoma Cells Exposed to 3 -Methylcholanthrene [PDF]

open access: yes, 2009
Cytochrome P4501A1 (CYP1A1), an enzyme known to metabolize polycyclic aromatic hydrocarbons, is regulated by the aryl hydrocarbon receptor (AhR). The involvement of protein kinase C (PKC) in the regulation of AhR signal transduction pathway, has been ...
