OBJECTIVE
This study aimed to explore the possible association between formaldehyde exposure and lung cancer risk.
METHODS
Data were collected in two population-based case-control studies conducted in Montreal, Canada. Cases were individuals diagnosed with incident, histologically-confirmed lung
The synthesis and preliminary evaluation of a doxorubicin-formaldehyde conjugate tethered to the nonsteroidal antiandrogen, cyanonilutamide (RU 56279), for the treatment of prostate cancer are reported. The relative ability of the targeting group to bind to the human androgen receptor was studied as
The synthesis of a doxorubicin-formaldehyde conjugate bound to the nonsteroidal anti-androgen cyanonilutamide, via a cleavable tether, and binding of the construct to cell free androgen receptor (AR) as a function of tether design were previously reported. Cyanonilutamide bearing a linear alkyne
This article reviews the available data on the carcinogenicity of formaldehyde from experimental and epidemiologic studies and makes recommendations for further research. Two definitive chronic inhalation bioassays on rodents have demonstrated that formaldehyde produces nasal cancer in rats and mice
For the first time, the National Health and Nutrition Examination Survey (NHANES) released data on hemoglobin adducts of formaldehyde (HCHO) in public domain for US children aged 6-11 years, adolescents aged 12-19 years, and adults aged > = 20 years for 2015-2016. This study was undertaken to
This case-control study of nasal and paranasal sinus tumors, in males diagnosed between 1978 and 1981 in the Netherlands, was designed to identify environmental risk factors. Special attention was given to assessing any association between nasal cancer and an occupational history of possible
The Formaldehyde Institute (FI) sponsored additional Poisson regression analysis of lung cancer mortality data from the joint National Cancer Institute (NCI)/FI cohort study of workers exposed to formaldehyde to investigate the previously reported effects of plant and latency period and to assess
Formaldehyde is a naturally occurring chemical found in every human cell. It has been in widespread use for over a century as a disinfectant and preservative agent, and more recently in a number of industrial products. Animal studies indicate that formaldehyde is a rat carcinogen at high levels (>
Development of chemotherapeutic/preventive drugs that selectively kill cancer - the Holy Grail of cancer research - is a major challenge. A particular difficulty arises when chemotherapeutics and radiation are found to be rather ineffective against quiescent cancer cells in solid The effects of exposure to benzo[a]pyrene (BAP) and formaldehyde (HCHO), alone and combined, on the induction of carcinogenesis in rat tracheal implants was determined as the number of growth-altered cell populations (tumor-initiation sites, TIS) per trachea. While exposure twice-weekly for 4.5
Studies of breast cancer therapy have examined the improvement of bispecific trastuzumab/pertuzumab antibodies interacting simultaneously with two different epitopes of the human epidermal growth factor receptor 2 (HER2). Here, we describe the creation and production of plant-made bispecific
Histone deacetylase inhibitory prodrugs that are metabolized to carboxylic acid(s) and aldehyde(s) possess antineoplastic properties. Formaldehyde-releasing prodrugs were shown to be the most potent. The objective of this study was to gain understanding on the mode of action of these prodrugs in
In this study, Ti-mineral superfine powders (Ti-MSP) encapsulated in urea-formaldehyde resin microcapsules (Ti-MSP@UF-MC) were successfully prepared via a one-step microemulsion method for the first time. Because of the strong confinement effects, the Ti-MSP@UF-MC possessed perfect microwave heating
The recent discovery that the clinically important antitumor drugs doxorubicin and daunorubicin alkylate DNA via catalytic production of formaldehyde prompted the synthesis of derivatives bearing formaldehyde. Reaction of the parent drugs with aqueous formaldehyde at pH 6 produced in 40-50% yield
Selected ion flow tube-chemical ionization mass spectrometry was used to measure formaldehyde levels in human breast cancer cells in comparison with levels in cells treated with the antitumor drugs doxorubicin (DOX) and daunorubicin (DAU) and the daunorubicin-formaldehyde conjugate Daunoform (DAUF).
