Ovarian cancer is one of the most common diseases of the female reproductive system. The aim of this study was the investigation of the antitumor cisplatin effect on ascitic fluid tumor cells in the ovarian cancer experimental model by digital cytomorphometry and cell bioinformatic analysis.
Female Wistar rats were inoculated by ovarian cancer strain. After ovarian cancer transplantation rats were divided into two groups: control group-without cisplatin treatment, the experimental group-under cisplatin treatment. The ascitic fluid was taken on the 9-th day after tumor cell inoculation. Digital cytomorphometric and cytobioinformatic analysis were used to study ascitic fluid cancer cell morphofunctional changes under cisplatin treatment.
Digital cytomorphometric characteristics of rat ovarian cancer ascitic cells were obtained. Tumor cells were classified into four groups according to their geometric size: small, medium, large, "gigantic". The algorithm and the computer program based on tumor cell morphometric characteristics were created to calculate such cell bioinformatic characteristic as information redundancy coefficient R. Three parameters were determined as the criteria of cisplatin effect on cancer cells: cell number, nuclear/cytoplasmic ratio, R-value.
Data obtained suggest that cisplatin reduces the total cell number, the nuclear/cytoplasmic ratio and R-value thus indicates a decrease in cellular resistance and adaptive potential. The digital cytomorphometry and bioinformatics could be recommended as a testing system in the experimental or clinical study.
卵巢癌是女性生殖系统最常见的疾病之一。本研究旨在通过数字细胞形态计量学和细胞生物信息学分析,研究顺铂对卵巢癌实验模型腹水肿瘤细胞的抗肿瘤作用。
雌性 Wistar 大鼠接种卵巢癌细胞株。卵巢癌移植大鼠分为两组:对照组-无顺铂治疗,实验组-顺铂治疗。在肿瘤细胞接种后第 9 天采集腹水。采用数字细胞形态计量学和细胞生物信息学分析方法,研究顺铂处理对腹水癌细胞形态功能的影响。
获得了大鼠卵巢癌腹水细胞的数字细胞形态计量学特征。根据其几何大小将肿瘤细胞分为四组:小、中、大、“巨大”。根据肿瘤细胞形态计量学特征创建了算法和计算机程序,以计算信息冗余系数 R 等细胞生物信息学特征。确定了三个参数作为顺铂对癌细胞作用的标准:细胞数量、核/细胞质比、R 值。
数据表明,顺铂降低了总细胞数量、核/细胞质比和 R 值,表明细胞的抵抗力和适应潜力下降。数字细胞形态计量学和生物信息学可以作为实验或临床研究的测试系统。
