目的
2
探究不同浓度双氢睾酮(DHT)对毛囊生长和毛囊细胞增殖的影响及其与miR-133b表达的关系,然后进一步探究miR-133b对毛乳头细胞的增殖和诱导能力的影响。
方法
2
体外显微分离人毛囊,选取生长期的毛囊进行培养,显微镜下每日测量并拍摄不同浓度的DHT处理组(10
-8
、10
-7
、10
-6
和10
-5
mol/L)和对照组各组毛囊的生长长度,免疫荧光检测各组毛母质细胞Ki-67表达量评估毛囊增殖能力,qRT-PCR检测各组毛囊中miR-133b的表达量。通过Lipofectamine 2000转染miR-133b mimics及miR-133b NC至人毛乳头细胞中,CCK-8检测各组人毛乳头细胞增殖能力,qRT-PCR及Western Blot检测毛乳头细胞诱导能力指标Versican、ALP、β-catenin的mRNA及蛋白水平的相对表达量。
结果
2
与对照组相比,DHT 10
-5
mol/L实验组对毛囊的生长的抑制作用有统计学意义(
P
<
0.05),DHT 10
-5
mol/L实验组进入退行期的时间提前;其他组生长长度与对照组相比无统计学意义。免疫荧光及qRT-PCR显示,与对照组相比,DHT 10
-5
mol/L实验组毛母质细胞中Ki-67阳性细胞较少且毛囊中miR-133b的相对表达量明显升高,相当于对照组的(3.17±0.26)倍(
P
<
0.01)。CCK-8显示,miR-133b mimics组OD450低于miR-133b NC组(
P
<
0.05);qRT-PCR显示,在mRNA水平,miR-133b mimics组Versican、ALP、β-catenin的相对表达量均低于miR-133b NC组(
P
<
0.001、
P
<
0.01和
P
<
0.01)。Western blot显示,在蛋白水平,miR-133b mimics组Versican、ALP、β-catenin的相对表达量同样均低于miR-133b NC组(
P
<
0.01、
P
<
0.001和
P
<
0.01)。
结论
2
高浓度DHT可能通过调控miR-133b的表达抑制人毛乳头细胞的增殖活性及诱导能力,最终抑制人毛囊的生长及增殖。
Objective
2
To explore the effects of different concentrations of 5α-dihydrotestosterone (DHT) on growth and proliferation of human hair follicles (HFs) and their relationship with miR-133b expression, then further explore the role of miR-133b in the proliferation and inducibility of human dermal papille cells.
Methods
2
HFs were isolated by microdissection, then the anagen isolated HFs were cultured and divided into different concentrations of DHT treatment groups (10
-8
mol/L, 10
-7
mol/L, 10
-6
mol/L, 10
-5
mol/L) and the blank control group. The HF growth and morphology were measured and evaluated. The expression of Ki-67 in hair matrix cells and miR-133b were detected by immunofluorescence assay and qRT-PCR respectively. Lipofectamine 2000 was used to transfect miR-133b mimics and miR-133b NC into human dermal papilla cells. CCK-8 was used to assess the proliferation ability of human dermal papilla cells. qRT-PCR and Western Blot were performed to evaluate respectively the mRNA and protein levels of the markers associated with inductive ability of dermal papilla cells, such as Versican, ALP and β-catenin.
Results
2
Compared with the control group, no other treatment groups but the DHT 10
-5
mol/L group showed statistically significant inhibitory effect on HF growth (
P
<
0.05). The catagen in the DHT 10
-5
mol/L group appeared earlier than that in the control group and there was no statistically significant difference in HF growth between other treatment groups and the control group. The DHT 10
-5
mol/L group showed lower percentage of Ki-67-positive cells in hair matrix cells and significantly increased relative expression of miR-133b in HFs, 3.17±0.26 times more than that in the control group (
P
<
0.01). CCK-8 assay revealed that the OD450 value in the miR-133b mimics group was lower than that in the miR-133b NC group (
P
<
0.05). qRT-PCR revealed that the mRNA expression levels of Versican, ALP, and β-catenin in the miR-133b mimics group were all lower than those in the miR-133b NC group (
P
<
0.001,
P
<
0.01,
P
<
0.01). Western Blot revealed that the protein expression levels of Versican, ALP, and β-catenin in the miR-133b mimics group were also lower than those in the miR-133b NC group (
P
<
0.01,
P
<
0.001,
P
<
0.01).
Conclusions
2
High concentrations of DHT may inhibit the growth and proliferation of HFs via regulating the expression of miR-133b, thus affect the proliferation and inducibility of human dermal papilla cells.
