University Graduate School of Health Sciences, Biochemistry Program, Master
Thesis, Ankara, 2020. In this study, it was aimed to determine the effect of application
Bisphenol A (BPA) and Fulvestrant (ICI) chemical to HepG2 human hepatoma cells on
proliferation, wound healing, E-cadherin, N-cadherin, vimentin proteins and apoptosis
(caspase 3/7) in cells. BPA is an endocrine disrupter commonly used in the industry and
has an estrogen-like effect. Fulvestrant is an estrogen receptor antagonist. The% cell
viability in HepG2 cells treated with BPA, ICI, BPA and ICI combination was determined
by MTT assay. The effects of BPA and ICI combination on HepG2 cell viability were
evaluated according to the Talalay-Chou method. Migration in HepG2 cells was
determined by wound healing method. The protein levels of E-cadherin, N-cadherin and
vimentin in cells were measured with the Elisa kits. Apoptosis in HepG2 cells was
measured by ApoTox-Glo ™ Triplex Test. It was observed that 8 nM BPA applied to
HepG2 cells increased cell viability, while 160 nM ICI and BPA and ICI combination
treatment reduced cell viability. The Talalay-Chou method explained that the effect
observed as a result of the combination of BPA and ICI against HepG2 cell viability is due
to a synergistic interaction. It was also determined that BPA increased the cytotoxic effect
of ICI. In wound-formed HepG2 cells, BPA, BPA and ICI combination treatment showed
that % wound size is decreased. The protein level of E-cadherin in HepG2 cells decreased
in BPA and ICI combination treatment. The protein level of N-cadherin increased with the
combination of ICI and BPA; and ICI. No changes in the protein level of vimentin were
observed. When apoptosis luminescence data were evaluated, it was determined that BPA
and ICI combination application increased apoptosis and BPA application was found to
affect necroptosis. The results of this thesis study explain that applying 8 nM BPA and
160 nM ICI to HepG2 cells affects the proliferation, wound healing and apoptosis in the
cells
