Molecular motors: how to make models that can be used to convey the concept of molecular ratchets and thermal capture.

A wide variety of cellular processes use molecular motors, including processive motors that move along some form of track (e.g., myosin with actin, kinesin or dynein with tubulin) and polymerases that move along a template (e.

Neonatal experiences differentially influence mammary gland morphology, estrogen receptor {α} protein levels, and carcinogenesis in BALB/c mice.

Prevention of breast cancer can be achieved with a better understanding of the factors contributing to normal breast development. Because the breast develops postnatally, alterations in the development and lifetime activity of the neuroendocrine system may set up an environment that increases cancer risk. The present study examined how two neonatal experiences over the first 3 weeks of life influence normal and malignant mammary gland development in female BALB/c mice.
