Abstract

Objectives: Breast cancer (BC) is the most commonlydiagnosed cancer in women worldwide with a high mortalityrate, despite early detection and treatment. Spindleand kinetochore-associated complex subunit 3 (SKA3) isclosely correlated with patient outcomes in several cancers.The present study aimed to elucidate the role of SKA3 in BC.Methods: The biological functions of SKA3 was investigatedby proliferation and migration assays in MDA-MB-231 cells with stable SKA3 knockdown and Hs578T cellsectopically expressing SKA3. Gene Expression Omnibusdatasets were utilised to determine the correlation betweenSKA3 expression and clinical features of BC patients.Results: We confirmed that SKA3 mRNA expression ishigher in breast tumour tissue than in normal tissue, andthat higher SKA3 expression is associated with poor survivalrate of BC patients. Knockdown of SKA3 reduced MDA-MB-231 cell proliferation and migration, whereas SKA3 overexpressionenhanced the proliferative and migratory abilityof Hs578T cells. We also found that SKA3 is involved inregulating cell cycle progression in mitotic exit.Conclusions: These results suggest that SKA3 is correlatedwith BC cell proliferation and migration by promoting cellcycle progression, and could be a novel potential therapeutictarget for BC treatment.

Özet

Giriş: Meme kanseri (BC), erken tespit ve tedaviye rağmen, yüksek mortalite oranı ile dünya çapında kadınlarda en sık teşhis edilen kanserdir. Kromozomların bağlandığı lifler ve kinetokor ile ilişkili kompleks alt birim 3 (SKA3), çeşitli kanser türlerinde hasta sonuçlarıyla yakından ilişkilidir. Amaç: Bu çalışma, SKA3’ün BC’deki rolünü aydınlatmayı amaçlamaktadır. Yöntemler: SKA3’ün biyolojik fonksiyonları, stabil SKA3 knockdown’lu MDA-MB-231 hücrelerinde ve SKA3’ü ektopik olarak eksprese eden Hs578T hücrelerinde proliferasyon ve migrasyon deneyleri ile araştırıldı. Genİfadesi Omnibus veri setleri, BC hastalarının SKA3 ekspresyonu ile klinik özellikleri arasındaki ilişkiyi belirlemek için kullanıldı. Bulgular: SKA3 mRNA ekspresyonunun göğüs tümör dokusunda normal dokudan daha yüksek olduğunu ve daha yüksek SKA3 ekspresyonunun BC hastalarının zayıf hayatta kalma oranı ile ilişkili olduğunu doğruladık. SKA3’ün yok edilmesi, MDA-MB-231 hücre proliferasyonunu ve göçünü azaltırken, SKA3 aşırı ekspresyonu, Hs578T hücrelerinin proliferatif ve göç etme kabiliyetini arttırdı. Ayrıca SKA3’ün mitotik çıkışta hücre döngüsü ilerlemesinin düzenlenmesinde rol oynadığını bulduk. Sonuçlar: Bu sonuçlar, SKA3’ün, hücre döngüsü ilerlemesini teşvik ederek BC hücre proliferasyonu ve göçü ile ilişkili olduğunu ve BC tedavisi için yeni bir potansiyel terapötik hedef olabileceğini düşündürmektedir.
