Investigation Into Roseburia Intesinalis For Optimal Growth And Survivability Conditions For Potential Probiotic Use, Lisa Rana Felczak Jan 2017

Investigation Into Roseburia Intesinalis For Optimal Growth And Survivability Conditions For Potential Probiotic Use, Lisa Rana Felczak

Wayne State University Theses

Obesity and diabetes is an epidemic of increasing concern. Certain novel bacteria have been found to be an aid in reversing some of the mechanisms associated. This study focused on investigating the optimal stability conditions for R.intestinalis that can associate with an increase in growth. First, environmental conditions were tested to find the optimal conditions associated with each. Once growth conditions were found, generation time was calculated and various prebiotics were used to investigate a potential for additional growth. Next, common antibiotics were tested to see if the R.intestinalis could still show growth when exposed. Large batches of R.intestinalis were …


Protein Phosphatase 2a Function And Regulation In Insulin Resistant Human Skeletal Muscle Cells, Shukurat Sulaiman Jan 2017

Protein Phosphatase 2a Function And Regulation In Insulin Resistant Human Skeletal Muscle Cells, Shukurat Sulaiman

Wayne State University Theses

Protein Phosphatase 2A (PP2A), a major serine/threonine phosphatase involved in insulin signaling pathway, plays a critical role in the development of insulin resistance and type 2 diabetes (T2D), which is characterized with hyperinsulinemic hyperglycemic condition. Moreover, majority of the glucose disposal takes place in the skeletal muscle which is also the main tissue responsible for insulin resistance. The catalytic subunit of PP2A (PP2Ac) can interact with multiple regulatory subunits and other regulatory proteins as well as substrates. These interactions are important for maintain normal PP2A function and subsequent cell signaling. We hypothesized that hyperinsulinemic hyperglycemic condition and insulin stimulation would …
