| Comments: | The tissue donor suffered from xeroderma pigmentosum and was the son of HTZ17BE (ATCC CRL-1361 ). The cells display UV induced unscheduled DNA synthesis at 30% to 60% of normal. |
||
| Propagation: | ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. |
||
| Subculturing: | Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:3 is recommended Medium Renewal: 2 to 3 times per week Remove spent medium, add fresh 0.25% trypsin for 3 to 5 minutes, remove trypsin and let the culture sit at room temperature for 10 to 20 minutes. Add fresh medium, aspirate and dispense into new flasks. Subculture every 8 to 9 days. |

文献和实验17-酮甾类(酮类固醇) 17-ketosteroid,17 oxosteroid
甾类骨架上第 17位碳原子上的氧基的化合物之总称,缩写 17KS。在生物体内,是由 17位羟基的酶促氧化和 C17 -C20 键切断生成的。在尿中含有来自副肾皮质的去氢表雄酮及其硫酸酯,睾丸酮的代谢物雄酮和表雄酮等。雌酮也以 17-酮甾类的形态存在着。因为副肾皮质和卵巢肿瘤患者的尿中的排出量很高,所以可作为临床的诊断指标。又因 17-酮甾类在碱性间 -硝基苯溶液中呈紫色,所以可进行定量测定。
C18 H24 O2 雌甾 -1, 3, 5( 10) -三烯 -3, 17-二醇。系代表性的性激素,可用卵巢、胎盘等制备,在卵泡液、胎盘、妊娠马尿中均可检出。进入子宫上皮细胞后,与性激素受体形成复合体进入细胞核,从而促进新的蛋白质合成,具有引起细胞增殖的作用。此外,能影响未成熟或切除卵巢的大鼠或小鼠的阴道分泌物,使呈现由角化细胞组成的显微镜象,所以也用作生物试验。在生物体内,在 17β -羟甾类脱氢酶的作用下氧化成为雌酮。 17α -羟甾体性激素的作用弱。作为女性
甾类(化合物)17α-羟化酶 steroid 17α-hy- droxylase,s eroid 17α-monooxygeoase
甾类(化合物)17α-羟化酶 steroid 17α-hy- droxylase,s eroid 17α-monooxygeoase 存在于睾丸、肾上腺的微粒体部分。是一种在甾类分子的17α位置上引入羟基的酶。EC1、14、99、9。需要有分子态氧和NADPH存在,与P-450有关。例如将黄体酮和孕(甾)烯醇酮各自成为17α-羟基黄体酮和17α-羟基孕烯醇酮。在鼠的肾上腺中不存在此酶。
