Immunotherapy strategies are very promising treatments for cancer patients. Specifically, Immune checkpoint inhibitor therapy focusing on the PD-1/PD-L1 pathway shows long-lasting positive results in many cancer patients. Unfortunately, not all the patients can benefit from this highly effective treatment. Hence, there is a great need for predictive biomarkers. Immunohistochemical (IHC) staining has been used as a way of predicting patient response, yet shows many problems. For example, IHC utilizes an invasive biopsy and sample fixing, which creates an incomplete and delayed picture of the patient’s biochemistry and the tumor microenvironment, consequently ignoring metastases.

The purpose of this study ...


Mechanisms Mediating The Pro-Fibrotic Effects Of Estradiol, Haley Fulton Nov 2018

Mechanisms Mediating The Pro-Fibrotic Effects Of Estradiol, Haley Fulton

Georgia Undergraduate Research Conference (GURC)

Scleroderma is a connective tissue disease which promotes fibrosis of the skin and internal organs. Scleroderma patients have upregulated production of fibrotic extracellular matrix proteins and upregulated serum estradiol levels compared to control subjects. Estradiol effects eukaryotic transcription and gene expression when it enters the nucleus via one of its nuclear hormone receptors. Estrogen receptor one/ estrogen receptor alpha (ESR1) is present on the nuclear membrane and binds the ligand estrogen. These experiments were designed to study the various isoforms of ESR1 and determine if gene expression of ESR1 was greater in fibroblasts and human skin stimulated with estradiol than ...
