Two known genes lie within the implicated genetic interval. One is FTO (a locus associated with fat mass and obesity), which has been implicated in nucleic acid demethylation and is highly expressed in the arcuate nucleus of the hypothalamus; the other, called fantom, or FTM (KIAA1005 or RPGRIP1L), begins transcription at a location only 200 base pairs upstream from the 5' end of FTO. FTM is a structural component of the ciliary body, present on all cells, that plays a role in a wide range of cellular and organ functions.9 Elements of the cilium are mutant in Bardet Biedl syndrome, which includes obesity among its characteristic phenotypes.10

有两个已知的基因存在于基因间隔中，一个是FTO（与脂肪体积和肥胖相关的基因位点），它在核酸脱甲基中发挥作用并且在下丘脑弓状核中高表达，另一个称作FTM，其在FTO 5'-末端的上游序列仅200个碱基对中开始转录，FTM是睫状体的结构组成部分，在所有细胞中都要表达，并在细胞和器官功能中发挥广泛的作用。

In a word, mad1 gene or mad1 combining with c-myc gene could inhibit TCCB cell proliferation but not normal fibrocytes in vitro and in vivo, which targeted hTERT, suppressed its transcription and expression, and down-regulated the expression of cyclin D1 and TGF-β1, to further block the cell cycle, change cell morphology and suppress proliferation.

综上所述，mad1基因或mad1联合c-myc基因能在体内外抑制TCCB细胞的增殖，但对正常成纤维细胞无明显影响，二者以hTERT为作用靶点，抑制其转录和表达，并下调cyclin D1和TGF-β1的表达，进而阻止细胞周期、改变细胞形态和抑制癌细胞的增殖。

Methods Cells were maintained in DMEM medium with 10% fetal bovine serum. Five days before the beginning of experiments, the cells were seeded in phenol red-free DMEM medium containing 5% charcoal dextran-treated FBS. The cells were harvested, and seeded in 6-well culture plates or in 75ml flacks. After NP, BisA and DBP treatments for 72h, the cells were harvested, and mRNA and protein expression of PCNA, bcl-2 and bax were detected by reverse transcription-polymerase chain reaction and immunohistochemistry, respectively.

方法］T47D细胞在含10%胎牛血清的DMEM培养液中进行常规传代培养，实验前将细胞转移至无酚红DMEM（含5%活性碳葡聚糖苷处理过的FBS）中继续培养5d，收集细胞，PBS洗涤后接种於内置盖玻片的6孔板或75ml培养瓶中，用32×10^(-7)mol/L NP、32×10^(-7)mol/L BisA及32×10^(-6)mol/L DBP对细胞分别处理72h，用半定量RT-PCR技术观察这3种化合物对核增殖抗原PCNA、bcl-2及bax mRNA表达的影响，并用免疫组化方法对结果进行验证。
