摘要: 目的 研究孕激素受体膜组分1(progesterone receptor membrane component 1,PGRMC1)对激素诱导的乳腺癌细胞的促增生作用,采用单用雌二醇(estradiol,E2)/周期序贯(sequential combination)/连续联合(continuous combination)不同的治疗方案,观察其对乳腺癌细胞增生的影响。方法 采用脂质体转染法将T47D稳定转染后,对转染空质粒(T47D-HA-vector)或转染PGRMC1(T47D-HA-PGRMC1)的T47D乳腺癌细胞系,分别用E2(0.1、0.01、0.001 nmol/L),或周期序贯/连续联合方案刺激6 d后,采用CCK-2法检测乳腺癌细胞的增生。结果 单用E2(0.1、0.01、0.001 nmol/L),T47D-HA-vector细胞未出现明显增生(P>0.05),T47D-HA-PGRMC1在E2浓度为0.1 nmol/L时与对照组(56%,P<0.05)及与T47D-HA-vector(36%,P<0.05)比均出现明显增加的细胞增生;周期序贯方案,T47D-HA-PGRMC1在E2/炔诺酮(norethisterone,NET)(E2=0.001 nmol/L)刺激时与对照组(82%,P<0.05)及与T47D-HA-vector(63%,P<0.05)比均显著地促进细胞增生。T47D-HA-vector在E2/NET(E2=0.1 nmol/L)刺激时与对照组相比显著地促进细胞增生(37%,P<0.05),T47D-HA-PGRMC1在E2/屈螺酮(drospirenone,DRSP)或E2/NET(E2=0.1 nmol/L)刺激时与对照组(105%,170%,P<0.05)及与T47D-HA-vector(84%,133%,P<0.05)比均显著地促进细胞增生;采用连续联合方案时,T47D-HA-PGRMC1在E2/DRSP或E2/NET(E2=0.001 nmol/L)刺激时与对照组(77%,158%,P<0.05)及与T47D-HA-vector(60%,136%,P<0.05)比均显著地促进细胞增生。T47D-HA-vector在E2/NET(E2=0.1 nmol/L)刺激时与对照组相比显著地促进细胞增生(44%,P<0.05),T47D-HA-PGRMC1在E2/DRSP或E2/NET(E2=0.1 nmol/L)刺激时与对照组(129%,174%,P<0.05)及与T47D-HA-vector(97%,131%,P<0.05)比均显著地促进细胞增生。结论 PGRMC1能够明显促进周期序贯/连续联合方案诱导的乳腺癌增生,与周期序贯方案相比,连续联合方案对T47D增生的促进作用更加明显。

Abstract: Objective To investigate the effect of progesterone receptor membrane component 1 (PGRMC1) on the risk of hormone induced breast cancer, and compare the effects of different treatment regimens:estradiol (E2)/sequential combination/continuous combination(E2/DRSP、E2/NET) on breast cancer proliferation. Methods After stabilized transfection by lipofection, T47D cells transfected with vector(T47D-HA-vector) or PGRMC1(T47D-HA-PGRMC1) were stimulated with E2 alone (0.1, 0.01, 0.001 nmol/L), or sequential/continuous combination. CCK-2 method was performed to measure cell proliferation. Results When treated with E2 (0.001, 0.01, 0.1 nmol/L) alone, T47D-HA-vector cells did not show significant proliferation (P>0.05). At concentration of 0.1 nmol/L, T47D-HA-PGRMC1 cell reached a significant increase in cell proliferation compared with the control group (56%, P<0.05) and compared with T47D-HA-vector group (36%, P<0.05); when treated with sequential combination, T47D-HA-PGRMC1 cell under E2/NET treatment (E2=0.001 nmol/L) showed a significant increase in cell proliferation compared with the control group (82%, P<0.05) and T47D-HA-vector group (63%, P<0.05). Under the same stimulation, when the concentration of E2 reached 0.1 nmol/L, T47D-HA-vector showed a significant increase compared with the control group (37%, P<0.05), and for the T47D-HA-PGRMC1 cell line, when under E2/drospirenone (DRSP) or E2/norethisterone (NET) stimulation (E2=0.1 nmol/L), a significant increase compared with the control group (105%, 170%, P<0.05) and T47D-HA-vector group (84%, 133%, P<0.05) was observed; when treated with the continuous combination, the T47D-HA-PGRMC1 cell line showed a significant increase in cell proliferation under E2/DRSP or E2/NET stimulation (E2=0.001 nmol/L) compared with the control group (77%, 158%, P<0.05) and T47D-HA-vector group(60%, 136%, P<0.05). The T47D-HA-vector cell line showed a significant increase under E2/NET stimulation (E2=0.1 nmol/L) compared with the control group (44%, P<0.05), and the T47D-HA-PGRMC1 cell line under E2/DRSP or E2/NET stimulation (E2=0.1 nmol/L) showed a significant increase in cell proliferation compared with the control group (129%, 174%, P<0.05) and T47D-HA-vector group (97%, 131%, P<0.05). Conclusion PGRMC1 can significantly promote the proliferation of breast cancer cells induced by sequential/continuous combination. Compared with the sequential combination, the continuous combination promoted a higher proliferation of T47D.
