Abstract

Amaç
Lokal ve sistemik faktörlerin, östrojen reseptörü pozitif
meme kanseri riskinde artış olan postmenopozal
obez kadınlarda meme kanseri hücrelerinin büyümesini
yönlendirdiği gösterilmiştir. Postmenapozal
dönemdeki obez kadınlarda, dolaşımdaki girelin hormonunun
azaldığı, bazı tümör hücreleri tarafından
üretildiği ve ayrıca tümör büyümesini etkilediği gösterilmiştir.
Bu çalışmada, adiponektin uygulamasının
östrojen reseptörü pozitif MCF-7 meme kanseri hücre
hattındaki rolünü ve girelin seviyeleri üzerine olan etkilerini
araştırmayı amaçladık.
Gereç ve Yöntem
MCF-7 meme kanseri hücre hattı 2 boyutlu kültürde
çoğaltıldı. MCF-7 meme kanseri hücrelerine artan
konsantrasyonlarda adiponektin (50-5000 ng/mL) ile
muamele edilerek inhibisyon dozu belirlendi. MCF-7
meme kanseri hücre hattına 50, 100, 250 ve 500 ng/
mL konsantrasyonda adiponektin uygulanarak 24, 48
ve 72. Saatlerde örneklerde girelin seviyeleri enzim
bağlı immünosorbent analizi (ELISA) ile ölçüldü.
Bulgular
24, 48 ve 72. saate alınan MCF-7 meme kanseri hücre
hattı kültür örneklerinde 50, 100, 250 ve 500 ng/mL
adiponektin konsantrasyonuna bağlı olarak proliferasyonun
azaldığı bulundu. 24, 48 ve 72. saate alınan
MCF-7 meme kanseri hücre hattı kültür örneklerinde
50, 100, 250 ve 500 ng/mL adiponektin konsantrasyonuna
bağlı olarak girelin miktarında artış oluştuğu
bulundu.
Sonuç
Çalışmamızda MCF-7 meme kanseri hücre hattında
(ER/PR pozitif) anti-kanserojenik özelliği kanıtlanmış
olan ve aynı zamanda obezite ile negatif korelasyon
gösteren adiponektinin, girelin ile karşılıklı etkileşimlerinin,
ER pozitif meme kanserlerindeki rolünü ortaya
koymuş olduk.

EFFECT OF ADIPONECTIN ON MCF-7 PROLIFERATION AND GHRELIN LEVEL

Abstract

Objective
Local and systemic factors have been shown to drive
the growth of breast cancer cells in postmenopausal
obese women who are at increased risk of
estrogen receptor-positive breast cancer. In obese
postmenopausal women, it has been shown that
circulating ghrelin hormone is decreased, produced
by some tumor cells, and also affects tumor growth.
In this study, we aimed to investigate the role of
adiponectin administration in estrogen receptor
positive MCF-7 breast cancer cell line and its effects
on ghrelin levels.
Material and Method
The MCF-7 breast cancer cell line was propagated
in 2D culture. The inhibition dose was determined by
treating MCF-7 breast cancer cells with increasing
concentrations of adiponectin (50-5000 ng/mL).
Ghrelin levels were measured at the 24th, 48th
,and 72nd hours by enzyme-linked immunosorbent
assay (ELISA) by administering adiponectin at a
concentration of 50, 100, 250 and 500 ng/mL to the
MCF-7 breast cancer cell line.
Results
In MCF-7 breast cancer cell line culture samples taken
at the 24th, 48th and 72nd hours, proliferation was
found to decrease depending on 50, 100, 250 and
500 ng/mL adiponectin concentration. It was found
that the amount of ghrelin increased depending on 50,
100, 250 and 500 ng/mL adiponectin concentration in
MCF-7 breast cancer cell line culture samples taken
at 24th, 48th and 72nd hours.
Conclusion
In our study, we revealed the role of adiponectin,
which has proven anti-carcinogenic properties in the
MCF-7 breast cancer cell line (ER/PR positive) and
also negatively correlated with obesity, and ghrelin, in
ER-positive breast cancers.
