Few studies have investigated the effects produced by combinations of polysaccharides and chemotherapeutic drugs in cancer treatment. We hypothesized that a combination of polysaccharides (COP) from Lentinus edodes and Tricholoma matsutake would improve the efficacy of 5-fluorouracil (5-FU)-mediated inhibition of H22 cell growth.
Mice were injected H22 cells and then treated with either 5-FU, polysaccharides from Tricholoma matsutake (PTM), polysaccharides from Lentinus edodes (PL), PTM+PL, 5-FU+PTM, 5-FU+ PL, or 5-FU + COP. The tumor weight and volume, and splenic CD4 + and CD8 + T cell frequencies, were determined. Additionally, splenic natural killer (NK) cell and cytotoxic T lymphocyte (CTL) activities were assessed and the serum levels of tumor necrosis factor-alpha (TNF-alpha), Interleukin-2 (IL-2), and Interferon-gamma (IFN-gamma) were measured.
Compared with mice from the control, 5-FU, PL, PTM, PTM + PL, 5-FU + PL, and 5-FU + PTM groups, mice treated with 5-FU + COP showed: (a) significantly reduced tumor weight and volume (P < 0.05); (b) significantly higher serum levels of TNF-alpha, IL-2, and IFN-gamma (P < 0.05); (c) significantly increased CD4+ and CD8+ T cell frequencies in the spleen (P < 0.05); and (d) significantly increased splenic NK cell and CTL activities (P < 0.05). The tumor weight and volume in mice treated with 5-FU+PL or 5-FU+PTM were significantly reduced compared with mice treated with 5-FU alone (P < 0.05). Serum levels of TNF-alpha, IL-2, and IFN-gamma, frequencies of CD4 + and CD8+ T cells in the spleen, and splenic NK and CTL activities were also significantly increased in mice treated with 5-FU+PL or 5-FU+PTM compared with mice treated with 5-FU alone (P < 0.05).
Polysaccharides from Lentinus edodes and Tricholoma matsutake could enhance the efficacy of 5-FU-mediated H22 cell growth inhibition.
很少有研究调查多糖和化疗药物联合在癌症治疗中的作用。我们假设香菇和松口蘑多糖(COP)的组合将提高 5-氟尿嘧啶(5-FU)介导的 H22 细胞生长抑制的疗效。
向小鼠注射 H22 细胞,然后用 5-FU、松口蘑多糖(PTM)、香菇多糖(PL)、PTM+PL、5-FU+PTM、5-FU+PL 或 5-FU+COP 进行处理。测定肿瘤重量和体积,以及脾 CD4+和 CD8+T 细胞频率。此外,评估脾自然杀伤(NK)细胞和细胞毒性 T 淋巴细胞(CTL)活性,并测量肿瘤坏死因子-α(TNF-α)、白细胞介素-2(IL-2)和干扰素-γ(IFN-γ)的血清水平。
与对照组、5-FU、PL、PTM、PTM+PL、5-FU+PL 和 5-FU+PTM 组的小鼠相比,用 5-FU+COP 处理的小鼠表现出:(a)肿瘤重量和体积明显降低(P<0.05);(b)血清 TNF-α、IL-2 和 IFN-γ水平显著升高(P<0.05);(c)脾 CD4+和 CD8+T 细胞频率显著升高(P<0.05);和(d)脾 NK 细胞和 CTL 活性显著增加(P<0.05)。与单独用 5-FU 处理的小鼠相比,用 5-FU+PL 或 5-FU+PTM 处理的小鼠的肿瘤重量和体积明显降低(P<0.05)。与单独用 5-FU 处理的小鼠相比,用 5-FU+PL 或 5-FU+PTM 处理的小鼠的血清 TNF-α、IL-2 和 IFN-γ水平、脾 CD4+和 CD8+T 细胞频率以及脾 NK 和 CTL 活性也显著增加(P<0.05)。
香菇和松口蘑多糖可增强 5-FU 介导的 H22 细胞生长抑制作用。
