Objective:

To establish an LC-MS/MS method for the determination of the abundance data of dexamethasone-related metabolic enzymes and transporters in the placenta of Chinese pregnant women.

Methods:

A Shim-pack GISS-HP C18 (100 mm×2.1 mm, 1.9 μm) chromatographic column was used, and the mobile phases were consisted of 0.2% formic acid-water (phase A) and 0.2% formic acid-acetonitrile (phase B) with gradient elution at a flow rate of 0.2 mL·min-1. The post-column phase C consisted of 0.5% ethylene glycol-acetonitrile was added at a flow rate of 0.1 mL·min-1, and the ESI source positive ion MRM mode was used for quantitative analysis. The established method was investigated methodologically and the expression levels of 11β hydroxysteroid dehydrogenase 1(11β-HSD1), 11β hydroxysteroid dehydrogenase 2(11β-HSD2), cytochrome P450 3A4 enzyme (CYP3A4) and P-glycoprotein protein (P-gp) were quantitatively analyzed in the placenta of Chinese pregnant women in the third trimester.

Results:

The established LC-MS/MS method had a linear range of 0.1-100 nmol·L-1(r >0.999). The precision and accuracy results met the requirements of the biological sample analysis method verification in Chinese Pharmacopoeia (RSD≤15%), and the stability results showed that the samples were stability. The protein abundance of 11β-HSD2, 11β-HSD1, CYP3A4 and P-gp were (84.46±59.97) pmol·g-1, (11.44±3.73) pmol·g-1, (8.83±2.78) pmol·g-1 and (7.94±4.10) pmol·g-1, respectively. Besides, the results of the study also showed that there was no significant difference in the distribution of related metabolic enzymes and transporters in different parts of the placenta. However, there was a significant difference in the abundance of P-gp in the placenta between Chinese people (7.94±4.10) pmol·g-1 and white people (4.41±2.46) pmol·g-1.

Conclusions:

The LC-MS/MS method established in this study has high accuracy and sensitivity and is suitable for detecting the abundance values of dexamethasone-related metabolic enzymes and transporters in human placenta.

目的:

建立LC-MS/MS方法测定中国孕妇胎盘中地塞米松相关代谢酶和转运体的丰度数据。

方法:

采用Shim-pack GISS-HP C18(100 mm×2.1 mm,1.9 μm)色谱柱,柱前由0.2%甲酸-水(A)和0.2%甲酸-乙腈(B)组成的流动相,以0.2 mL·min-1的流速进行梯度洗脱,柱后以0.1 mL·min-1的流速加入0.5%乙二醇-乙腈(流动相C),采用ESI源正离子MRM模式进行定量分析。对所建立的方法进行方法学考察并对中国孕妇孕晚期胎盘中11β羟基类固醇脱氢酶1(11β-HSD1)、11β羟基类固醇脱氢酶2(11β-HSD2)、细胞色素P450 3A4酶(CYP3A4)和P-糖蛋白(P-gp)蛋白表达量进行定量分析。

结果:

建立的LC-MS/MS分析测定方法的线性范围为0.1~100 nmol·L-1(r>0.999);精密度和准确度结果均符合《中华人民共和国药典》对于生物样品分析方法学验证的要求(RSD≤15%),稳定性结果显示样品稳定性良好。11β-HSD2、11β-HSD1、CYP3A4和P-gp的蛋白丰度分别为(84.46±59.97) pmol·g-1、(11.44±3.73) pmol·g-1、 (8.83±2.78) pmol·g-1和(7.94±4.10) pmol·g-1。同时研究结果显示相关代谢酶和转运体在胎盘不同部位的分布没有显著差异,但中国人胎盘P-gp的丰度(7.94±4.10) pmol·g-1和白人(4.41±2.46) pmol·g-1相比存在显著性差异。

结论:

本研究建立的LC-MS/MS方法准确度和灵敏度高,适用于检测人类胎盘中地塞米松相关代谢酶和转运体的丰度值。

Objective:

To establish an LC-MS/MS method for the determination of the abundance data of dexamethasone-related metabolic enzymes and transporters in the placenta of Chinese pregnant women.

Methods:

A Shim-pack GISS-HP C18 (100 mm×2.1 mm, 1.9 μm) chromatographic column was used, and the mobile phases were consisted of 0.2% formic acid-water (phase A) and 0.2% formic acid-acetonitrile (phase B) with gradient elution at a flow rate of 0.2 mL·min-1. The post-column phase C consisted of 0.5% ethylene glycol-acetonitrile was added at a flow rate of 0.1 mL·min-1, and the ESI source positive ion MRM mode was used for quantitative analysis. The established method was investigated methodologically and the expression levels of 11β hydroxysteroid dehydrogenase 1(11β-HSD1), 11β hydroxysteroid dehydrogenase 2(11β-HSD2), cytochrome P450 3A4 enzyme (CYP3A4) and P-glycoprotein protein (P-gp) were quantitatively analyzed in the placenta of Chinese pregnant women in the third trimester.

Results:

The established LC-MS/MS method had a linear range of 0.1-100 nmol·L-1(r >0.999). The precision and accuracy results met the requirements of the biological sample analysis method verification in Chinese Pharmacopoeia (RSD≤15%), and the stability results showed that the samples were stability. The protein abundance of 11β-HSD2, 11β-HSD1, CYP3A4 and P-gp were (84.46±59.97) pmol·g-1, (11.44±3.73) pmol·g-1, (8.83±2.78) pmol·g-1 and (7.94±4.10) pmol·g-1, respectively. Besides, the results of the study also showed that there was no significant difference in the distribution of related metabolic enzymes and transporters in different parts of the placenta. However, there was a significant difference in the abundance of P-gp in the placenta between Chinese people (7.94±4.10) pmol·g-1 and white people (4.41±2.46) pmol·g-1.

Conclusions:

The LC-MS/MS method established in this study has high accuracy and sensitivity and is suitable for detecting the abundance values of dexamethasone-related metabolic enzymes and transporters in human placenta.

新生儿呼吸窘迫综合征(respiratory distress syndrome,RDS),又称新生儿肺透明膜病,指新生儿出生后不久即出现进行性呼吸困难和呼吸衰竭等症状,主要是由于缺乏肺泡表面活性物质所引起[1]。若不及时进行治疗,患儿于出生后4~12 h会出现进行性呼吸困难、呻吟、发绀等症状,严重者发生呼吸衰竭。
在对RDS治疗指南中,推荐使用皮质激素对妊娠28~34周存在早产风险的孕妇至少在分娩前24 h给予单疗程治疗(6 mg,每12 h给药1次,共给药4次,肌肉注射)[2]。地塞米松是一种人工合成的糖皮质激素,一般用于风湿性疾病、哮喘、严重过敏、慢性阻塞性肺病等疾病,其在RDS实际临床治疗中得到广泛应用[3]
虽然地塞米松促进胎肺成熟的疗效确定,但近年来产前应用糖皮质激素对胎儿生长发育的不良影响越来越受到关注。胎儿过早、过多地接触糖皮质激素可导致胎儿宫内生长受限,并与成年期某些疾病如糖尿病、高血压等有关[4]。已有研究表明[5-6],地塞米松浓度在胎儿体内变异大,目前原因不清,可能与其经胎盘转运时受到多个酶和转运体的影响有关。有文献研究表明[7-9],涉及地塞米松跨胎盘转运的代谢酶和转运体主要包括细胞色素P450 3A4酶(cytochrome P450 3A4 enzyme,CYP3A4)、11β羟基类固醇脱氢酶1(11β-hydroxysteroid dehydrogenase 1,11β-HSD1)、11β羟基类固醇脱氢酶2(11β-hydroxysteroid dehydrogenase 2,11β-HSD2)和P-糖蛋白(P-glycoprotein,P-gp)。但这些代谢酶和转运体在中国孕妇胎盘的丰度信息尚未见报道。
靶向蛋白组学是近些年发展起来的用于蛋白质定量的分析方法,相比于传统的蛋白质印迹法和酶联免疫吸附测定法等,具有较高的准确度和灵敏度。为更好地理解地塞米松跨胎盘转运机制,本研究利用液相色谱-质谱联用(LC-MS/MS)建立了同时对样品中CYP3A4、11β-HSD1、11β-HSD2和P-gp进行定量的检测方法,并对临床试验收集的中国健康孕妇胎盘样品进行测定,统计分析酶和转运体对地塞米松跨胎盘的机理。

临床研究为“中国孕妇药物经胎盘转运的体外体内外推模型研究”,经北京大学第三医院医学科学研究伦理委员会审查通过,伦理审查批号为(2020)医伦审第(094-03)号。
在受试者首次产检(第6周±7 d)时,符合入排标准的健康受试者即入组,在受试者分娩后收集受试者的废弃胎盘样本。生产结束时快速将胎盘放置于医用低温储备箱,用经过75%医用酒精消毒的手术剪分别剪取胎盘边缘处、边缘与脐带中间处和脐带处3个部分组织,分别记为A、B和C。每部分组织大约剪取5~10 g,剪取时注意去除大血管和钙化组织。所有操作均在4 ℃环境下进行,将取好组织放置于-80 ℃冰箱备用。
解冻胎盘并剪取5~10 g左右,用预冷的生理盐水漂洗3~4次,充分洗去血凝块。用眼科手术剪刮除胎盘绒毛,随后将组织剪碎,加入5倍体积预冷的匀浆液(50 mmol·L-1 Tris-HCl,pH 7.0,150 mmol·L-1 KCl,2 mmol·L-1 EDTA-2Na和0.1 mmol·L-1 PMSF。具体制备过程:称取Tris-HCl 1 592.0 mg,加入纯水200 mL溶解,用1 mol·L-1氢氧化钾溶液调节pH到7.0,再加入KCl 2 247.7 mg和EDTA-2Na 150.38 mg,到此为不含PMSF的预备匀浆液;称取PMSF 17.420 mg溶于乙醇10 mL中,得到PMSF母液,临用前,用不含PMSF的预备匀浆液稀释100倍),电动匀浆机匀浆2~3 min。随后750 g离心30 min (4 ℃),收集上清液;于15 000 g离心30 min (4 ℃),收集上清液;于105 000 g离心60 min (4 ℃),收集沉淀重悬于预冷的0.25 mol·L-1的蔗糖-磷酸盐缓冲液(蔗糖8 557.5 mg溶解于PBS 100 mL)中,得到微粒体溶液。为了可以在-80 ℃中长期保存,可加入20%甘油并分装备用。
称取约胎盘组织50 mg,剪碎,加入膜蛋白提取试剂A 1 mL和混合蛋白酶抑制剂10 μL匀浆,轻微振摇,4 ℃孵育10 min。随后匀浆液在4 ℃,16 000 g离心15 min。弃去上清液,沉淀重悬于400 μL的3%的脱氧胆酸钠溶液中,得到细胞膜蛋白提取液。采用Bradford法[10]测定总膜蛋白的浓度,使用匀浆液调整蛋白浓度至约2 mg·mL-1
用50 mmol·L-1碳酸氢铵溶液将微粒体样品蛋白浓度调整到2 mg·mL-1,移取微粒体蛋白或总膜蛋白30 μL,加入50 mmol·L-1碳酸氢铵溶液45 μL和200 mmol·L-1 DTT溶液 10 μL,涡旋后95 ℃孵育10 min。冷却后暗处操作,加入400 mmol·L-1 IAM溶液10 μL,涡旋后室温暗处孵育20 min。加入100 ng·μL-1胰酶工作液(Sigma aldrich,将胰酶溶解于50 mmol·L-1乙酸制成1 μg·μL-1胰酶储备液,临用前使用50 mmol·L-1碳酸氢铵将胰酶储备液稀释10倍)15 μL,涡旋后37 ℃孵育过夜。最后加入含有0.2%甲酸的20%乙腈溶液(含有5 nmol·L-1混合内标55 μL,涡旋混合,10 000 g离心10 min,取上清即得多肽样品溶液,用于质谱分析。
根据已有文献[11],选取LQEEIDAVLPNK作为CYP3A4的特征肽段,FYDPLAGK作为P-gp的特征肽段。目前尚未有研究使用蛋白组学的方法对人体组织中11β-HSD1和11β-HSD2酶丰度进行定量分析,文献中无二者的特征肽段可供参考,故本研究利用Ultimate 3000-Orbitrap Fusion Lumos超高效液相色谱-四极杆-静电场轨道阱-线性离子阱串联质谱仪,对酶微粒体样品中的蛋白和多肽进行分离鉴定,数据经ProteinPilotTM软件与UniProt蛋白数据库对比分析,筛选11β-HSD1和11β-HSD2潜在的特征肽段。特征肽段的选取需满足以下要求:肽段长度在7~22个氨基酸序列,相对分子质量在2 000以下;没有翻译后修饰的氨基酸序列;没有单核苷酸多态性的氨基酸序列;没有半胱氨酸(C)、甲硫氨酸(M)、色氨酸(W)等不稳定的氨基酸;没有RR、KK、RK、KR(R:精氨酸;K:赖氨酸)等不稳定的序列;没有跨膜区域[12]。同时使用加利福尼亚大学旧金山分校(UCSF)所提供的多样性质谱分析工具:MS-Digest模拟胰蛋白酶对11β-HSD1和11β-HSD2进行酶切的情况,结果和上述非靶向蛋白组学的数据进行相互验证,最终选取VIVTGASK作为11β-HSD1的特征肽段,ALLQLLR作为11β-HSD2的特征肽段。
对上述所选择的肽段按照氨基酸序列进行合成作为标准品,同时合成对应的同位素多肽作为内标。标准品和同位素内标的氨基酸序列信息见表1
采用Shim-pack GISS-HP C18 (100 mm×2.1 mm,1.9 μm)色谱柱,流动相A为0.2%甲酸-水,流动相B为0.2%甲酸-乙腈,流动相C为0.5%乙二醇-乙腈,柱前采用流动相A和流动相B,以0.2 mL·min-1的流速进行梯度洗脱(详见表2),流动相C作为质谱信号增强溶剂接入色谱柱后,以0.1 mL·min-1的流速,柱温35 ℃,进样量10 μL。
采用LC-MS 8060NX超高效液相色谱-三重四极杆质谱联用仪,电喷雾离子源,正离子模式(ESI+),雾化气流量为3 L·min-1,干燥气流量为8 L·min-1,加热气流量为12 L·min-1,接口温度为350 ℃,脱溶剂温度为600 ℃,DL温度为250 ℃,加热块温度为400 ℃。
精密平行称取2份各肽段标准品(表3)溶于纯化水(浓度及制备过程见表4)。取各标准品溶液适量(5 mmol·L-1标准品溶液吸取2 μL,2 mmol·L-1标准品溶液吸取5 μL),混合并加入超纯水986 μL,涡旋混匀,即得10 μmol·L-1的混合标准品工作液。同时吸取5 mmol·L-1内标溶液2 μL及2 mmol·L-1内标溶液5 μL,混合,加入超纯水986 μL,涡旋混匀,即得10 μmol·L-1的混合内标工作液。
将混合标准品工作液用纯化水稀释成浓度分别为0.1、0.2、0.5、1、3、10、30、50和100 nmol·L-1的混合标准曲线溶液C1~C9(详见表5)。混合质控溶液制备方法同混合标准曲线溶液制备过程(详见表6),得到浓度分别为0.3、8和80 nmol·L-1的混合低、中、高浓度质控溶液。移取各混合标准曲线溶液或混合质控溶液30 μL,加入200 mmol·L-1 DTT溶液 10 μL、50 mmol·L-1碳酸氢铵溶液45 μL、400 mmol·L-1 IAM溶液 10 μL、100 ng·mL-1胰酶工作液15 μL、0.2%甲酸的20%乙腈水溶液(含5 nmol·L-1的混合内标)55 μL,涡旋混合,10 000 g离心10 min,取上清进行质谱分析。
本研究根据2020年版《中华人民共和国药典》第四部通则9012《生物样品定量分析方法验证指导原则》中相关要求进行方法验证,包括专属性、线性、准确度与精密度、稳定性。
分别对空白基质[移取匀浆液30 μL,加入200 mmol·L-1 DTT溶液10 μL、50 mmol·L-1碳酸氢铵溶液45 μL、400 mmol·L-1 IAM溶液 10 μL,100 ng·mL-1胰酶工作液15 μL、0.2%甲酸的20%乙腈水溶液(含5 nmol·L-1的混合内标)55 μL]和10 nmol·L-1混合标准曲线溶液进行分析,考察方法的专属性。
结果显示,在所建立的色谱和质谱检测条件下,不同肽段能够得到较好的分离,空白基质对各肽段的测定无干扰。见图1
取“2.4.2”项下混合标准曲线溶液,按“2.3”项下条件进样检测,得2条标准曲线。利用前后2条标准曲线对线性进行评估,可接受标准为至少75%的浓度点的回推浓度应在85%~115%,定量下限应在80%~120%,且应包含至少1个定量下限浓度点和1个定量上限浓度点。相关系数r应≥0.99。
使用LabSolutions对数据进行处理,使用定量处理中校准曲线类型为二次曲线,零截距为未过原点,加权为1/C2的方法对样品峰面积进行计算。结果见图2,所有目标肽段r均>0.999。
按照“2.4.2”项下方法配制低、中、高浓度质控溶液,每个浓度平行6份。利用随行标准曲线定量,测定3个批次混合低、中和高浓度质控溶液的日内和日间精密度和准确度。准确度可接受标准为混合低、中和高浓度质控溶液标示值的±15%;精密度的可接受标准为混合低、中和高浓度质控溶液的RSD≤15%。
精密度和准确度结果见表7,日内准确度和日间准确度的混合低、中和高浓度质控溶液都在标示值的±15%以内;日内精密度和日间精密度的混合低、中和高浓度质控溶液的RSD%均≤15%。该分析方法的准确度和精密度符合《中华人民共和国药典》对于生物样品分析方法方法学验证的要求,说明准确度和精密度良好。
按照“2.4.2”项下方法配制混合低、中和高浓度质控溶液,每个浓度平行3份。分别于-20 ℃和室温冻融循环3次后取出,并于室温下保存至少4 h后进样分析;对于短期和长期稳定性,分别于-20 ℃冷冻保存24 h和30 d,取出后于室温下保存至少4 h后进样分析。溶液稳定的标准为每个浓度水平平均浓度准确性在理论浓度的85%~115%。
结果如表89所示,短期稳定性、长期稳定性和冻融稳定性的混合低、中和高浓度质控溶液都在标示值的±15%以内,证明溶液稳定性良好。
利用上述分析方法对不同胎盘样品进行检测,样品蛋白丰度(pmol·g-1)采用如下公式进行计算:
样品蛋白丰度=测定浓度×体积×稀释倍数×1 000/组织质量
使用R语言(V 4.0.1)软件对样品检测结果数据进行正态分析、方差齐性分析、非参数检验和事后多重比较等。
对于CYP3A4和11β-HSD1共检测了10个胎盘,对于P-gp和11β-HSD2共检测了12个胎盘。其中有7个胎盘检测了所有酶和转运体。
通过对样品检测结果的描述性统计分析可知(表10),在中国人足月胎盘中与地塞米松代谢相关的酶和转运体蛋白丰度从高到低分别为11β-HSD2 (84.46±59.97) pmol·g-1、11β-HSD1 (11.44±3.73) pmol·g-1、CYP3A4 (8.83±2.78) pmol·g-1和P-gp (7.94±4.10) pmol·g-1图3显示了具体的蛋白浓度分布情况。
将胎盘中各个酶和转运体不同取样部位A、B、C的蛋白丰度进行比较,考察它们在胎盘不同部位的分布是否有显著性差异。P-gp的取样部位C、11β-HSD1的取样部位C、11β-HSD2取样部位A和C的P<0.05,是非正态的,其余均符合正态分布。对数值进行lg或者ln转换后,再进行正态性检验,P-gp和11β-HSD1全部正态,11β-HSD2非正态;进行方差齐性检验,P-gp、CYP3A4和11β-HSD1 3组方差的P>0.05,均为齐性;对P-gp、CYP3A4和11β-HSD1进行事后多重比较,选择常用的Tukey、LSD和Bonferroni方法,结果显示,P-gp、CYP3A4和11β-HSD1各组内不同取样位置的A、B、C检测结果P>0.05,均无显著性差异(表11);对11β-HSD2进行非参数检验,结果P>0.05,未见显著性差异(表12)。
综上所述,P-gp、CYP3A4、11β-HSD1和11β-HSD2在胎盘不同部位的分布无显著性差异,可以不用考虑取样部位对检测结果的影响,这一结果也与白人胎盘的统计结果一致。
将文献[13]中白人人群孕晚期胎盘P-gp丰度数据与本研究实测的中国孕晚期胎盘丰度数据(n=12)进行比较,考察二者之间是否有显著性差异(图4)。白人数据的P<0.05,不符合正态,对其进行对数转换;对数转换后,2组数据P>0.05,均符合正态分布;2组数据方差P>0.05,均为齐性;用独立样本T检验,P<0.05,2组有显著性差异(表13)。以上数据说明中国人胎盘P-gp丰度与白人胎盘P-gp丰度存在着显著性差异,白人胎盘的P-gp丰度数据不能直接替代中国人胎盘的P-gp丰度数据。
本研究利用靶向蛋白组学方法对中国孕妇胎盘中地塞米松相关代谢酶和转运体的蛋白丰度进行了定量测定,该方法不依赖于蛋白质标准品的可用性。通过本研究表明相关代谢酶和转运体在胎盘的不同部位的分布没有显著差异,但中国人孕晚期胎盘处的P-gp丰度和白人胎盘处的P-gp丰度存在着显著差异。
本研究中关于流动相的组成最初选用A相(0.2%甲酸-水)和B相(0.2%甲酸-乙腈)进行梯度洗脱。该条件下低浓度标准曲线样品无法准确定量,因此考虑在流动相中加入促进多肽质谱响应的试剂乙二醇。经过对比分析该方法并不能有效提高目标肽段的响应,随后利用独立液相泵于柱后恒速输入含有乙二醇的乙腈溶液,结果质谱响应有明显提升,经过不同浓度乙二醇比例的测试,最终确定0.5%乙二醇作为C相进行目标肽段的分析。
本研究对于代谢酶和转运体蛋白丰度定量方法仍然存在一定局限性,首先本研究假设所有酶和转运体都存在于合体滋养层细胞膜上,且都具有活性[14],但一些其他类型的胎盘细胞(比如内皮细胞)上也存在一些酶或转运体[15],因此,本研究检测方法得到的结果可能会高估合体滋养层细胞质膜上的酶和转运体。此外,代谢酶或转运体的活性不一定和蛋白表达水平完全一致,因此后期也需要结合多种酶活测定方法对本研究结论进行补充和印证。再有,本研究中胎盘样品都是足月的,缺乏孕早期和孕中期等不同妊娠阶段的胎盘样品,无法考察妊娠发育动力学对胎盘中酶和转运体丰度含量变化的影响。此外,本研究只选取了1条肽段进行定量,后续可进一步考察其他特征肽段的选取对样品定量的影响。尽管仍有不足,本研究所建立的策略和分析方法能够用于4种涉及地塞米松转运和代谢相关的酶和转运体蛋白丰度的绝对定量分析,可为类似研究提供参考和依据。
本研究建立了人胎盘中11β-HSD1、11β-HSD2、CYP3A4和P-gp靶向蛋白组学定量分析方法,该方法专属性强,灵敏度高,方法学验证结果显示该方法能够用于中国孕妇胎盘中4种蛋白绝对丰度的测定。样品测定结果显示中国孕妇孕晚期胎盘样品中各代谢酶和转运体在不同部位的分布没有显著差异,但中国人足月胎盘中P-gp的丰度略高于白人足月胎盘中P-gp的丰度,且二者存在着显著性差异。
