Summary
Women may face higher lung cancer risks due to increased susceptibility to tobacco carcinogens. Estrogen signaling pathways in lung cells offer potential new targets for lung cancer treatment and prevention.
Area of Science:
- Oncology
- Endocrinology
- Molecular Biology
Background:
- Lung cancer is a leading cause of cancer death in the US.
- Emerging evidence suggests women have a higher susceptibility to tobacco-induced lung cancer compared to men.
- Estrogen and its receptors (ERs), particularly ERb, are implicated in lung carcinogenesis.
Purpose of the Study:
- To explore the role of estrogen signaling and its cross-talk with other pathways in lung cancer.
- To investigate potential new therapeutic strategies for lung cancer based on these molecular mechanisms.
Main Methods:
- Review of existing biochemical and genetic data on sex differences in lung cancer.
- Analysis of estrogen receptor presence and function in lung tissues and cell lines.
- Examination of estrogen's direct and indirect effects on lung cell gene transcription and signaling pathways.
Main Results:
- Estrogen receptors (ERb) are present and functional in normal lung and tumor cells.
- Estrogen directly stimulates estrogen-responsive genes and transactivates growth factor pathways, like the epidermal growth factor pathway.
- These pathways represent a potential mechanism for sex-based differences in lung cancer development.
Conclusions:
- Understanding estrogen signaling and cross-talk pathways is crucial for developing novel lung cancer treatments.
- These insights may lead to innovative combinatorial therapies and chemoprevention strategies for lung cancer.
- Targeting estrogen pathways could offer new hope for lung cancer patients with limited treatment options.

01:31Internal Receptors
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.
02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
01:15Receptor Downregulation in MVBs
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR activation may...

01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:26Signal Transduction: Overview
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

01:31Transducer Mechanism: Nuclear Receptors
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
