Real‐Time Evolutionary Landscape of the Bronchial Epithelium and Corresponding Dynamic Immune Cell Alterations in Lung Squamous Cell Carcinogenesis

open access: yesAdvanced Science, Volume 12, Issue 31, August 21, 2025.
Lung squamous cell carcinoma (LUSC) is often preceded by sequential premalignant lesions with an increasing probability of malignant progression. Using single‐cell RNA sequencing, the dynamic cellular evolution from normal lung to LUSC tissues is delineated; clonal structure of premalignant and malignant epithelium is reveled; the conversion of immune ...

Animal models of lung cancer: Phenotypic comparison of different animal models of lung cancer and their application in the study of mechanisms

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 7, Page 1229-1252, July 2025.
Grafts used to construct lung cancer animal models come from various sources, primarily cell lines, patient‐derived tumor tissues, and circulating tumor cells. Based on the sources of grafts and research objectives, lung cancer animal models can be categorized into several types: chemical‐induced models, orthotopic transplantation models, heterotopic ...

Aryl hydrocarbon receptors in osteoclast lineage cells are a negative regulator of bone mass.

open access: yesPLoS ONE, 2015
Aryl hydrocarbon receptors (AhRs) play a critical role in various pathological and physiological processes. Although recent research has identified AhRs as a key contributor to bone metabolism following studies in systemic AhR knockout (KO) or transgenic

Studies on Leukemogenesis in RF Mice by Oral Administration of 20-methylcholanthrene. I. Induction of Leukemia by Oral Administration of 20-methylcholanthrene [PDF]

open access: yes, 1964
1) RF mice were fed three times a week wih 0.1-0.15cc of 0.4 and 0.8% 20-methylcholanthrene in olive oil by means of a needle of a catheter. The mode of development of myelogenous and lymphocytic leukemias in these mice was studied by observation of the ...

Stimulation of Protein Synthesis and of RNA Polymerase Activity in the Liver of 3-Methylcholanthrene-Treated Rats

open access: yes, 1973
Following a single dose of 3-methylcholanthrene in rat liver the RNA polymerase activity of Mg++and Mn++/(NH4)2SO4- dependent forms is stimulated in isolated nuclei and particularly in the chromatin of extranucleolar fraction.

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.

Intrinsic mutagenicity and electrophilicity of 1-sulfooxy-3-methylcholanthrene: Implications for metabolic activation of the carcinogen 3-methylcholanthrene

open access: yes, 1995
Hydroxylation of a meso-anthracenic carbon atom with subsequent formation of a reactive ester bearing a good leaving group (e.g., sulfate) has been proposed as a possible biochemical mechanism responsible for DNA binding, mutagenicity and tumorigenicity ...

Using methylcholanthrene-induced fibrosarcomas to study tumor immunology

open access: yes, 2021
Mouse models of cancer are essential in furthering our understanding both of the mechanisms that drive tumor development and the immune response that develops in parallel, and also in providing a platform for testing novel anti-cancer therapies.

Morphology and Progression of Preneoplastic Changes in Methylcholanthrene-Induced Mouse Mammary Tumorigenesis

open access: yes, 1985
Susceptible BALB/c virgin female mice were treated with 3-methylcholanthrene in almond oil (0.5 %) by skin painting and killed at monthly intervals.
