To investigate whether 17 β-estradiol and progesterone regulate autophagy during spheroids formation via the classical genomic pathway we analyzed the influence of these steroids on the expression of genes involved in autophagy induction and formation of autophagosomes in MECs.
Ligand-activated ERs drive gene cascades comprising primary genes, whose transcription is directly controlled by the hormone through physical interaction of ERs with regulatory sites in the genome (genomic pathway) and/or with signal transduction effectors (non genomic pathway), as well as downstream genes whose activity depends upon the functions encoded by the primary responders [ 1, 4].
Currently, however, the accuracy of the approaches based on genomic pathways is not sufficient to predict the involvement of particular genes in microgravity-induced changes.
It is how we develop diagnostics, therapeutics and guide health care for patients — it all starts with understanding the biological mechanisms, the genomic pathways and how genotypes and phenotypes are related.
Transient and continuous administrations equally increased eNOS expression, implying that a short contact between hormone and cells is sufficient to trigger genomic pathways.
Conclusions: Our data suggest that the kinetics of contact of estrogen with the cells could represent a sensor for estrogen receptor (ER) signaling towards non-genomic or genomic pathways.
Pathology at Yale has many "firsts" to its credit, including leadership in documenting the pathology of pandemic flu, radiation injury, and environmental lung disease; methods for the diagnosis and assessment of lymphoproliferative disorders and genomic pathways of tumor resistance to targeted therapeutics.
The U.S. national labs are using deep learning to understand our genomic pathways, to advance drug development, and to improve cancer population health.
Our findings for axon guidance and ALS or PD do not preclude the role of other genomic pathways in the etiology of these disorders.
Thus, imaging-genomic analyses may prove invaluable in detecting novel targetable genomic pathways.
