Investigation of Anticancer Activity of Pecan Shell (Carya illinoensis)

Abstract

Background: Cancer is one of the diseases that developed by uncontrolled proliferation of cells and become more common every year. The inadequacy of existing treatment methods, the need for new methods with lesser side effects have increased. Phytotherapy, which has become widespread as one of the cancer treatment methods in recent years, has created the most remarkable candidate and a rapidly developing field. In this study, based on the phytotherapy method, the anticancer activity of the green outer bark of the pican nut (Carya illinoinensis) was investigated.
Materials and Methods: The anticancer activity of pican nut green bark on various cancer cell lines was tested using the cell culture method. In this context, the cytotoxic value of the green-shell hexane extract of pecan nut was tested on PC-3, DU-145, PNT1-A, HT-29, HCT-116 and HUVEC cell lines. The percentage of apoptotic cells was investigated with Annexin V/PI staining and cell cycle with PI staining.
Results: According to the experimental results, it was determined that pican nut green-outer shell hexa-ne extract showed highest cytotoxic effect on PC-3, which is the prostate cancer cell line (IC50: 40.32µg/ml). The percentage of apoptotic cells was found to be 94% and the of cells retained in the G0/G1 phase was 59.2%.
Conclusions: As a result of this study, it was determined that PC-3 cells suppressed cell division and triggered apoptosis in cells. Based on these results, it is predicted that the green-outer shell of pican nut is an alternative plant candidate that can be used in the treatment of cancer in the pharmacological field and will guide the studies to be done in this field.

Pikan Cevizi (Carya illinoensis) Kabuğunun Antikanser Aktivitesinin İncelenmesi

Abstract

Amaç: Kanser, hücrelerin kontrolsüz çoğalması sonucu ortaya çıkan ve her geçen yıl daha da yaygınlaşan hastalıkların başında gelir. Mevcut tedavi yöntemlerinin yetersizliği, seçici etkiye sahip ve nispeten daha az yan etkili yeni yöntem arayışı her geçen gün artmıştır. Son yıllarda kanser tedavi yöntemlerinden biri olarak yaygınlaşan fitoterapi, en dikkat çekici aday ve hızla gelişen bir alan oluşturmuştur. Bu çalışmada fitoterapi yönteminden yola çıkarak, pican cevizinin (Carya illinoinensis) yeşil-dış kabuğunun antikanser aktivitesi araştırılmıştır. Materyal ve Metod: Pican cevizi yeşil kabuğunun çeşitli kanser hücre hatları üzerindeki antikanser aktivitesi hücre kültürü yöntemi kullanılarak test edilmiştir. Bu kapsamda PC-3, DU-145, PNT1-A, HT-29, HCT-116 ve HUVEC hücre hatları, pikan cevizi yeşil-dış kabuğu hekzan ekstraktı ile tedavi edilerek sitotoksik değeri (MTT boyaması) belirlenmiştir. Belirlenen doz ve hücreler kullanılarak Annexin V/PI boyaması ile apoptotik hücre yüzdesi ve PI boyaması ile ise hücre döngüsü üzerine etkileri araştırılmıştır. Bulgular: Elde edilen deney sonuçlarına göre pican cevizi yeşil-dış kabuk hekzan ekstraktı seçici etki göstererek en yüksek sitotoksik etkiyi prostat kanseri hücre hattı olan PC-3 üzerine gösterdiği tespit edilmiştir (IC50: 40.32µg/ml). Belirlenen IC50’unda apoptotik hücre yüzdesi %94 ve G0/G1 fazında tutulan hücre miktarı ise %59.2 olduğu bulunmuştur. Sonuç: Bu çalışma sonucunda PC-3 hücrelerin, hücre bölünmesini yavaşlattığı ve hücrelerde apoptozisi tetiklediği tespit edildi. Bu sonuçlara göre, farmakolojik alanda pican cevizi yeşil-dış kabuğunun kanser tedavisinde kullanılabilecek alternatif bir bitki adayı olduğu ve bu alanda yapılacak çalışmalara yol gösterici olacağı öngörülmektedir.
