張雜谷提取物的抗氧化研究及蔗糖合成酶基因家族的生物信息學(xué)分析摘要：

本研究對張雜谷提取物的抗氧化能力及其對蔗糖合成酶基因家族的調(diào)控作用進(jìn)行了生物信息學(xué)分析。結(jié)果顯示，張雜谷提取物富含多種抗氧化物質(zhì)，能夠有效抑制DNA氧化損傷和減輕細(xì)胞內(nèi)氧化應(yīng)激。進(jìn)一步的RNA-seq分析表明，張雜谷提取物顯著調(diào)節(jié)了蔗糖合成酶基因家族的表達(dá)，并且通過KEGG通路分析發(fā)現(xiàn)，張雜谷提取物可以影響多種碳水化合物代謝通路的活性。此外，我們還利用基因共表達(dá)網(wǎng)絡(luò)構(gòu)建算法，發(fā)現(xiàn)在張雜谷提取物抗氧化過程中，有一些關(guān)鍵基因在不同的代謝途徑中協(xié)同作用，進(jìn)一步驗(yàn)證了張雜谷提取物對代謝和抗氧化的多重作用。本研究為探索張雜谷提取物在膳食中的應(yīng)用提供了新的理論依據(jù)。
