Cell Biology @ Penn

Signal Transduction


Identification of estrogen receptor positive cells within normal breast tissue.

The Penn campus includes an active group of laboratories engaged in investigations regarding, in its broadest context, the transfer of information within cells. This includes work on components of canonical signal cascades, such as protein tyrosine kinases, phospholipids, heterotrimeric G proteins, serine/threonine kinases and second messengers, as well as novel modes of intracellular communication. In addition to many collaborations and informal interactions, the cell biology community sponsors seminars and lectures related to signaling, a general signaling data/journal club, and a number of more specialized interest groups. The result is an environment that provides numerous opportunities for education and training while conducting high quality and high-impact signaling research.
