Expression of CYP2A3 mRNA and its regulation by 3-methylcholanthrene, pyrazole, and ß-ionone in rat tissues

open access: yesBrazilian Journal of Medical and Biological Research, 2003
Cytochrome P450 (CYP) 2A enzymes are involved in the metabolism of numerous drugs and hormones and activate different carcinogens. Human CYP2A6, mouse CYP2A5 and rat CYP2A3 are orthologous enzymes that present high similarity in their amino acid sequence

NK cells and NKT cells collaborate in host protection from methylcholanthrene-induced fibrosarcoma.

open access: yesInternational Immunology, 2001
NK1.1(+) V(alpha)14J(alpha)281(+) (NKT) cells can be induced by IL-12 therapy to mediate tumor rejection; however, methylcholanthrene (MCA)-induced fibrosarcoma is the only tumor model described where NKT cells play a natural role in controlling tumor ...

Pharmacological inhibition of IRAK4 kinase activity does not prevent cachexia in mice with pancreatic cancer

open access: yesJCSM Rapid Communications, Volume 6, Issue 2, Page 122-133, July/December 2023., 2023
Abstract Background Inflammation is a hallmark of cachexia; however, effective anti‐inflammatory treatments have not yet been identified. Interleukin‐1 receptor‐associated kinase 4 (IRAK4) is a key signalling node linking interleukin‐1 receptor (IL‐1R) and toll‐like receptor (TLR) activation to the production of multiple proinflammatory cytokines that ...

Improvement of antitumor therapies based on vaccines and immune-checkpoint inhibitors by counteracting tumor-immunostimulationw [PDF]

open access: yes, 2018
Immune-checkpoint inhibitors and antitumor vaccines may produce both tumor-inhibitory and tumor-stimulatory effects on growing tumors depending on the stage of tumor growth at which treatment is initiated.

Crocetin Downregulates the Proinflammatory Cytokines in Methylcholanthrene-Induced Rodent Tumor Model and Inhibits COX-2 Expression in Cervical Cancer Cells

open access: yesBioMed Research International, 2015
The effect of crocetin (C20H24O4) on methylcholanthrene- (MCA-) induced uterine cervical cancer in mice was studied in this paper. After the mice were treated orally with crocetin, maleic dialdehyde (MDA), polymorphonuclear cells (PMN), interleukin-1β ...

A perspective on the impact of radiation therapy on the immune rheostat. [PDF]

open access: yes, 2017
The advent and success of immune checkpoint inhibitors (ICIs) in cancer treatment has broadened the spectrum of tumours that might be considered "immunogenic" and susceptible to immunotherapeutic (IT) intervention. Not all cancer types are sensitive, and

The Carcinogenic Activity of Methylcholanthrene in Rats [PDF]

open access: yesThe American Journal of Cancer, 1940
Studies of induced Cysticercus sarcoma in rats have demonstrated (1) a direct relationship between the number of parasites in the host's liver and the duration of the latent period. An increase in the number of cysts decreased directly the average time interval before the onset of malignant disease and increased directly the probability of its ...

Inhibitory effects of Indigofera aspalathoides on 20-methylcholanthrene-induced chemical carcinogenesis in rats

open access: yesJournal of Carcinogenesis, 2011
Background: The anticancer and antioxidant effects of the aqueous extract of Indigofera aspalathoides on 20-methylcholanthrene (20-MCA) induced fibrosarcoma were investigated in male albino rats.

Methylcholanthrene-Induced Sarcomas Develop Independently from NOX2-Derived ROS.

open access: yesPLoS ONE, 2015
Reactive oxygen species (ROS) produced by the inducible NADPH oxidase type 2 (NOX2) complex are essential for clearing certain infectious organisms but may also have a role in regulating inflammation and immune response.
