Introduction

冰球是一項受歡迎的高強度競技運動，其速度快、持久性強，對運動員的體力、耐力、協(xié)調(diào)性等方面要求非常高。為了提高冰球運動員的成績和保護(hù)其健康，需要對其細(xì)胞及基因進(jìn)行深入研究。永生化細(xì)胞系的建立和基因表達(dá)研究可以為了解運動員的身體適應(yīng)和訓(xùn)練提供基礎(chǔ)支持。

MaterialsandMethods

選取10名有冰球運動經(jīng)驗的男性成年人作為研究對象，采集其皮膚組織樣本，利用ATCC提供的細(xì)胞轉(zhuǎn)染試劑包裹pRSV-t-T，pLNCX2和pCL-10A1質(zhì)粒，將轉(zhuǎn)染后的細(xì)胞進(jìn)行篩選和培養(yǎng)生成了冰球運動員的永生化細(xì)胞系。

利用qPCR分析永生化細(xì)胞系的耐力相關(guān)基因表達(dá)，分析了在運動員的低氧耐力和高強度訓(xùn)練時差異表達(dá)的基因。

Results

通過對冰球運動員皮膚組織的樣本進(jìn)行經(jīng)過長期的篩選和培養(yǎng)，建立了其永生化細(xì)胞系，經(jīng)過觀察和比較，發(fā)現(xiàn)其與常規(guī)細(xì)胞系相比更加穩(wěn)定，能夠保持活躍性。

基因表達(dá)結(jié)果顯示，在運動員低氧耐力和高強度訓(xùn)練時，一些與肌肉生長、代謝和運動適應(yīng)有關(guān)的基因表達(dá)出現(xiàn)了差異，如AMPK、PGC-1α、PPARγ、IGF1R等，這些差異表達(dá)的基因為進(jìn)一步了解冰球運動員適應(yīng)訓(xùn)練的機制提供了一些參考。

Conclusion

本研究成功建立了冰球運動員的永生化細(xì)胞系，并對其做基因表達(dá)研究，發(fā)現(xiàn)了一些與低氧耐力和高強度訓(xùn)練有關(guān)的基因表達(dá)差異，為進(jìn)一步研究冰球運動員的身體適應(yīng)和訓(xùn)練提供了一些基礎(chǔ)支持。這些新發(fā)現(xiàn)將有助于開發(fā)更好的訓(xùn)練方案和保護(hù)冰球運動員的健康。Abstract
