目的
2
探究乳酸(Lact)在高强度间歇训练(HIIT)介导的骨合成代谢中的作用及机制。
方法
2
①将18只小鼠分为Con组(不进行任何处理)、HT组(仅进行HIIT)、Lact组(仅注射L-乳酸钠),每组6只,然后取血进行Lact检测。②通过卵巢切除术(OVX)建立绝经后骨质疏松小鼠模型,然后分为OVX组(仅建模)、OVX+HIIT组(建模后进行HIIT)、OVX+HIIT+乳酸转运体抑制剂α-氰基-4-羟基肉桂酸(α-CHCA)组(建模后,进行HIIT的同时腹腔注射α-CHCA)及OVX+Lact组(建模后皮下注射L-乳酸钠),每组10只;Sham组小鼠不建模(
n
=10)。采用Micro-CT扫描分析骨微结构参数,通过HE染色和抗酒石酸酸性磷酸酶(TRAP)染色分别计数成骨细胞数量(N.Ob)和破骨细胞数量(N.Oc/BS);使用Scanco Micro-CT40扫描仪扫描分析以下微结构参数:骨密度(BMD)、骨体积分数(BV/TV)、骨小梁数量(Tb.N)、骨小梁厚度(Tb.Th)、骨小梁分离度(Tb.Sp)、皮质骨厚度(Ct.Th)及骨面积分数(BA/TA)。③体外培养小鼠成骨前体细胞MC3T3-E1,并分为Control组(正常培养)、Lact-C组(给予20 mmol/L的L-乳酸钠)、α-CHCA组(给予0.4 mmol/L α-CHCA)及Lact+α-CHCA组(同时加入20 mmol/L L-乳酸钠和0.4 mmol/L α-CHCA)。碱性磷酸酶(ALP)染色、茜素红染色观察成骨分化和矿化结节;免疫荧光染色检测微管相关蛋白1轻链3(LC3)表达;Western blot检测Runt相关转录因子2(Runx2)、Osterix(Osx)和骨桥蛋白(OPN)、自噬相关蛋白Beclin-1、自噬接头蛋白p62、GATA结合蛋白4(GATA4)、Parkin蛋白表达及LC3-Ⅱ/LC3-Ⅰ水平。
结果
2
①小鼠进行HIIT 30 min后血浆Lact水平达峰值,Lact注射60 min后血浆Lact水平达峰值。②与OVX组相比,OVX+HIIT组和OVX+Lact组骨组织中的BMD、BV/TV、Tb.N、Tb.Th、Ct.Th、BA/TA和N.Ob均增加,Tb.Sp、N.Oc/BS减少,差异均有统计学意义(
P
<
0.05)。③体外实验显示:Lact处理增加成骨细胞矿化和分化活性,显著增强自噬流,表现为LC3-Ⅱ/LC3-Ⅰ、Beclin-1及成骨分化标志物Runx2、Osx和OPN表达升高,同时p62及GATA4蛋白表达下降,而抑制Lact转运均削弱此效应。
结论
2
在HIIT介导的骨合成代谢中,Lact通过激活自噬相关蛋白促进GATA4蛋白表达下降,进而驱动成骨细胞分化,缓解骨质疏松。
Objective
2
To investigate the role and mechanism of lactate (Lact) in bone anabolism mediated by high-intensity interval training (HIIT).
Methods
2
①Eighteen mice were divided into Con group (no treatment), HT group (underwent HIIT only), and Lact group (injected with sodium L-lactate only), with 6 mice in each group. Blood samples were then obtained for Lact detection. ②Postmenopausal osteoporosis mouse model was established by ovariectomy (OVX). The mice were then divided into OVX group (OVX only), OVX+HIIT group (underwent HIIT after modeling), OVX+HIIT+lactate transporter inhibitor α-cyano-4-hydroxycinnamic acid (α-CHCA) group (underwent HIIT combined with intraperitoneal injection of α-CHCA after modeling), and OVX+Lact group (underwent subcutaneous injection of sodium L-lactate after modeling), with 10 mice in each group. Mice in the Sham group (
n
=10) did not undergo modeling. Bone microstructural parameters were analyzed using Micro-CT scanning. The number of osteoblasts (N.Ob) and number of osteoclasts (N.Oc/BS) were assessed by HE staining and tartrate‑resistant acid phosphatase (TRAP) staining, respectively. The following microstructural parameters were measured using a Scanco Micro-CT40 scanner: bone mineral density (BMD), bone volume over total volume (BV/TV), trabecular number (Tb.N), trabecular thickness (Tb.Th), trabecular separation (Tb.Sp), cortical thickness (Ct.Th), and bone area over total area (BA/TA). ③Mouse preosteoblast MC3T3-E1 cells were cultured in vitro and divided into the Control group (normal culture), Lact-C group (treated with 20 mmol/L sodium L-lactate), α‑CHCA group (treated with 0.4 mmol/L α-CHCA), and Lact+α-CHCA group (treated with both 20 mmol/L sodium L-lactate and 0.4 mmol/L α-CHCA). Osteogenic differentiation and mineralized nodule formation were evaluated by alkaline phosphatase (ALP)
staining and alizarin red S staining.LC3 expression was detected by immunofluorescence staining. Western blot was used to detect the expression of Runt‑related transcription factor 2 (Runx2), Osterix (Osx), osteopontin (OPN), autophagy‑related protein Beclin‑1, autophagy adaptor protein p62, GATA‑binding protein 4 (GATA4), Parkin protein, and the LC3‑Ⅱ/LC3‑Ⅰ ratio.
Results
2
①In mice, plasma Lact levels peaked at 30 minutes after HIIT and at 60 minutes after Lact injection. ②Compared with the OVX group, the OVX+HIIT and OVX+Lact groups exhibited increased BMD, BV/TV, Tb.N, Tb.Th, Ct.Th, BA/TA and N.Ob in bone tissue, as well as decreased Tb.Sp and N.Oc/BS, all with statistically significant differences (
P
<
0.05). ③In vitro experiments showed that Lact treatment enhanced osteoblast mineralization and differentiation activity, significantly promoted autophagic flux, as evidenced by increased LC3-Ⅱ/LC3-Ⅰ ratio, Beclin-1 level and osteogenic markers Runx2, Osx, and OPN expression, decreased p62 and GATA4 proteins. These effects were attenuated by inhibiting Lact transport.
Conclusion
2
In HIIT-mediated bone anabolism, Lact promotes the decrease of GATA4 protein expression by activating autophagy-related proteins, thereby driving osteoblast differentiation and alleviating osteoporosis.
