We are combining top-down and bottom-up approaches to synthetic biology; we use tools of protein engineering and molecular biology, together with novel synthetic cell technologies, to understand and modulate biological processes in complex systems.
We study the genetics of complex traits: how variation in genome sequences influences individual molecular, cellular and organismal features. We also seek to understand the evolutionary forces that shape genomic diversity.
T2D is the most common chronic disease affecting human health, affecting more than 347 million individuals worldwide. T2D is a complex disease characterized by pancreatic β-cell failure to make sufficient amounts of insulin in the setting of obesity and insulin resistance in peripheral tissues. The risk for T2D is determined by many factors. Our genetic makeup can predispose us for T2D, and lifestyle can also reduce or exacerbate health risks. But in recent years, our studies and those of others have shown the importance of babies' time in the womb for influencing health over our lifespan. We and others have shown that poor uterine environments can increase the risk of many diseases in adulthood, including diabetes. Therefore, the long-term goal of the Alejandro Lab is to stop the vicious cycle of diabetes by launching a two-pronged research program for both intervention and prevention of this disease:

The Lange lab studies how steroid hormone receptor (SR) positive and hormone-influenced cancers escape molecular targeted therapies. Signal transduction is an essential role of SRs. Indeed, all SRs can rapidly activate cytoplasmic protein kinases and act as “growth factor sensors”. In this role, SRs are heavily phosphorylated by mitogenic protein kinases (MAPKs, AKT, CDKs) that are frequently elevated and activated in SR+ (breast and reproductive tract) cancers. Phosphorylation of SRs alters their binding partners and promoter selection and influences cancer cell fate/plasticity by regulating genes that specify proliferative, pro-survival, metabolic, and cancer stem cell programs. Identifying the required kinases and co-activator partners of phospho-SRs will enable the targeting of multiple signaling molecules in addition to SRs, which is predicted to halt cancer metastasis, prevent recurrence, and increase patient survival.
