Overexpression of a RHAMM isoform (RHAMMΔ163) transforms fibroblasts but the mechanisms underlying this oncogenic function are not well understood. RHAMMΔ163 binds to the mitotic spindle and centrosomes via a C-terminal leucine zipper; these interactions are predicted to regulate genomic stability and cell polarity and proposed to account for the oncogenic function of RHAMMΔ163. We hypothesized that RHAMM leucine zipper maintains mitotic spindle integrity and impacts directional cell migration through its interactions with microtubule and centrosome structures. The consequences of a mutated leucine zipper on cell division, cell motility, and tumorigenesis were assessed. Although mutant RHAMM …
Cortisol And Testosterone In Hair As Biological Markers Of Systolic Heart Failure, Justin Chan
Cortisol And Testosterone In Hair As Biological Markers Of Systolic Heart Failure, Justin Chan
Electronic Thesis and Dissertation Repository
Congestive heart failure (CHF) is associated with increased stress and alterations in metabolism, favoring catabolism over anabolism. Hormonal profiles of patients with heart failure have been assessed using serum and saliva as matrices, which are only point measurements and do not provide long-term information. Scalp hair is a novel matrix that allows for measurement of hormones over a period of several months. We aimed to evaluate whether levels of cortisol and testosterone and their ratio (C/T) in hair correlate with severity of heart failure. We conducted a prospective study in ambulatory male patients with a left ventricular ejection fraction (LVEF) …

The human placenta of different gestational ages is a readily available source for isolation of adult mesenchymal stem cell (MSC) for potential use in regenerative therapies. The chorionic villous region, the largest component of a placenta that interfaces with the maternal circulation, is a rich source of placental MSCs (PMSCs). To remain multipotent, PMSCs are best maintained in culture conditions that mimic the in vivo microenvironment. Insulin like growth factors (IGFs, IGF-I and -II) and oxygen tension are two of the most important microenvironmental factors in the placenta. They are of low concentration or tension respectively, at early gestation, and …
