The role of dietary profiles in promoting or reducing the risk of multiple types of cancer is increasingly clear, driving the search for balanced foods and nutraceuticals. The red seaweed has been used as human food showing a balanced nutritional profile. This study aims to test in vivo chemopreventive effects of against cutaneous pre-malignant lesions in transgenic mice for the human papillomavirus type 16 (HPV16). Forty-four female HPV or HPV mice received a standard diet or were supplemented with 10% for 22 consecutive days. Cutaneous lesions (ear and chest skin) were identified histologically. Complementarily, the weights and histology of internal organs as well as blood biochemical and DNA integrity parameters were also assessed. consistently reduced the incidence of epidermal dysplasia induced by HPV16 on both cutaneous sites. Moreover, biochemical, DNA integrity and histological analyses confirmed edibility as no signs of toxicity were found. Dietary supplementation with is an effective and safe chemopreventive strategy in this model.
饮食模式在促进或降低多种癌症风险方面的作用越来越明显,这促使人们寻找均衡的食物和营养保健品。红色海藻已被用作人类食品,具有均衡的营养特性。本研究旨在测试对人乳头瘤病毒 16(HPV16)转基因小鼠皮肤前恶性病变的体内化学预防作用。44 只雌性 HPV 或 HPV 小鼠接受标准饮食或补充 10%的饮食 22 天。通过组织学鉴定皮肤病变(耳朵和胸部皮肤)。此外,还评估了内脏器官的重量和组织学以及血液生化和 DNA 完整性参数。在两个皮肤部位,海藻均一致降低了由 HPV16 诱导的表皮发育不良的发生率。此外,生化、DNA 完整性和组织学分析证实了海藻的可食用性,未发现任何毒性迹象。在该模型中,用海藻补充饮食是一种有效且安全的化学预防策略。
