    Adipogenesis involves intricate molecular mechanisms regulated by various transcription factors and signaling pathways. In this study, we aimed to identify factors specifically induced during adipogenesis in the human preadipocyte cell line, SGBS, but not in the mouse preadipocyte cell line, 3T3-L1. Microarray analysis revealed distinct gene expression profiles, with 1460 genes induced in SGBS cells and 1297 genes induced in 3T3-L1 cells during adipogenesis, with only 297 genes commonly induced. Among the genes uniquely induced in SGBS cells, we focused on GALNT15, which encodes polypeptide N-acetylgalactosaminyltransferase-15. Its expression increased transiently during adipogenesis in SGBS cells but remained low in 3T3-L1 cells. Overexpression of GALNT15 increased mRNA levels of CCAAT-enhancer binding protein (C/EBPα) and leptin but had no significant impact on adipogenesis in SGBS cells. Conversely, knockdown of GALNT15 suppressed mRNA expression of adipocyte marker genes, reduced lipid accumulation, and decreased the percentage of cells with oil droplets. The induction of C/EBPα and peroxisome proliferator-activated receptor γ during adipogenesis was promoted or suppressed in SGBS cells subjected to overexpression or knockdown of GALNT15, respectively. These data suggest that polypeptide N-acetylgalactosaminyltransferase-15 is a novel regulatory molecule that enhances adipogenesis in SGBS cells.

    In adipose tissue, D-dopachrome tautomerase (DDT), a cytokine with structural similarity to macrophage migration inhibitory factor, is mainly expressed in adipocytes rather than preadipocytes and acts as an anti obesity adipokine in an autocrine manner. However, its transcriptional regulation is largely unknown. In order to explore molecules affecting DDT transcription, a chemical library screening using HEK293 cells stably expressing a DDT promoter-reporter construct was performed. Several derivatives of 5-aminoimidazole-4-carboxamide-1-beta-(D)-ribofuranoside (AICAR), an AMP-activated protein kinase (AMPK) activator, were identified as transcriptional activators of the DDT gene. Furthermore, DDT mRNA levels were reduced in SGBS adipocytes treated with compound C, an AMPK inhibitor, suggesting involvement of AMPK in DDT transcription. Overexpression of the FOXO1 constitutive active form reduced transcriptional activity of the DDT gene in SGBS cells, but increased it in HEK293 cells. Cell-type specific effects were also observed in the DDT gene expression of cells treated with AS1842856, a FOXO1 inhibitor. Finally, involvement of the mammalian target of rapamycin (mTOR) signaling in DDT transcription in SGBS adipocytes was investigated. Rapamycin, an inhibitor of mTOR, increased DDT mRNA levels and attenuated the inhibitory effects of compound C on DDT mRNA levels in SGBS adipocytes. In conclusion, DDT transcription may be regulated in a cell-dependent manner, and were enhanced by AMPK activation in SGBS adipocytes through inhibiting the mTOR signaling.

    本研究の目的は、下顎側方偏位が顔面軟組織形状に及ぼす影響を、非接触型三次元形状計測装置を用いて定量的に評価することである。徳島大学病院矯正歯科に来院した、先天異常を伴わない成人25症例を対象とした。正面頭部エックス線規格写真においてMenton(Me)が3.0mmを超えて側方偏位しているものを偏位群、Meの偏位をほとんど認めないものを非偏位群とし、非接触型三次元形状計測装置にて全被験者の顔面撮影を行った。三次元画像解析ソフトウェアを用いて、外眼角部、鼻部、鼻翼部、口角部、オトガイ部のFH平面と平行な各水平断面における、偏位側の非偏位側に対する軟組織の前方突出度を計測した。口角部およびオトガイ部では、偏位群の軟組織が非偏位群に比較して有意に前方突出し、また、偏位群において、口角部およびオトガイ部の軟組織の前方突出度とMeの側方偏位量の間に高い相関を認めた。以上のことから、三次元形状計測装置を用いることにより、顔面非対称の三次元的な定量評価が可能となり、下顎骨側方偏位症例におけるMeの偏位は、中顔面部の軟組織にはほとんど影響を与えず、下顔面部の軟組織のみに反映されていることが示唆された。(著者抄録)

    We previously identified D-dopachrome tautomerase (DDT) as a novel adipokine whose mRNA levels in adipocytes are negatively correlated with obesity-related clinical parameters, and which acts on adipocytes to regulate lipid metabolism. Here we investigated functions of DDT on preadipocytes. Recombinant DDT (rDDT) enhanced both the expression and secretion of interleukin-6 (IL-6) in SGBS cells, a human preadipocyte cell line. Treatment with rDDT increased levels of phosphorylated ERK1/2, but not p38, in SGBS cells, and rDDT-induced IL-6 mRNA expression was attenuated by pretreatment with an ERK inhibitor, U0126. Knockdown of CD74, but not CD44, inhibited rDDT-induced IL-6 mRNA expression in SGBS cells. These results suggested that the rDDT-induced IL-6 expression in preadipocytes occurred through the CD74-ERK pathway. Furthermore, in SGBS cells subjected to adipogenic induction, rDDT decreased the amount of triacylglycerol, number of cells with oil droplets, and levels of mRNA encoding adipocyte marker proteins. Increased expression of CCAAT/enhancer binding protein families and peroxisome proliferator-activated receptor gamma 2 during adipogenesis was inhibited in the cells treated with rDDT. These results suggested DDT to inhibit adipogenesis by suppressing the expression of genes encoding adipogenic regulators in preadipocytes. (C) 2012 Elsevier Ltd. All rights reserved.

    Adipose tissue is a critical exchange center for complex energy transactions involving triacylglycerol storage and release. It also has an active endocrine role, releasing various adipose-derived cytokines (adipokines) that participate in complex pathways to maintain metabolic and vascular health. Here, we found D-dopachrome tautomerase (DDT) as an adipokine secreted from human adipocytes by a proteomic approach. DDT mRNA levels in human adipocytes were negatively correlated with obesity-related clinical parameters such as BMI, and visceral and subcutaneous fat areas. Experiments using SGBS cells, a human preadipocyte cell line, revealed that DDT mRNA levels were increased in an adipocyte differentiation-dependent manner and DDT was secreted from adipocytes. In DDT knockdown adipocytes differentiated from SGBS cells that were infected with the adenovirus expressing shRNA against the DDT gene, mRNA levels of genes involved in both lipolysis and lipogenesis were slightly but significantly increased. Furthermore, we investigated AMP-activated protein kinase (AMPK) signaling, which phosphorylates and inactivates enzymes involved in lipid metabolism, including hormone-sensitive lipase (HSL) and acetyl-CoA carboxylase (ACC), in DDT knockdown adipocytes. The AMPK phosphorylation of HSL Ser-565 and ACC Ser-79 was inhibited in DDT knockdown cells and recovered in the cells treated with recombinant DDT (rDDT), suggesting that down-regulated DDT in adipocytes brings about a state of active lipid metabolism. Furthermore, administration of rDDT in db/db mice improved glucose intolerance and decreased serum free fatty acids levels. In the adipose tissue from rDDT-treated db/db mice, not only increased levels of HSL phosphorylated by AMPK, but also decreased levels of HSL phosphorylated by protein kinase A (PKA), which phosphorylates HSL to promote its activity, were observed. These results suggested that DDT acts on adipocytes to regulate lipid metabolism through AMPK and/or PKA pathway(s) and improves glucose intolerance caused by obesity.

    A 6-year-old boy, diagnosed with Crouzon syndrome, had moderate exorbitism, a concave profile, an anterior crossbite of -4.0 mm, and a skeletal Class III jaw-base relationship caused by midfacial hypoplasia. At age 8 years 9 months, a LeFort III osteotomy was performed, and distraction osteogenesis was immediately started with the rigid external distractor system. The midface was advanced approximately 10.0 mm for 6 days, including overcorrection. After the distraction, a reverse headgear was used for 6 years to prevent relapse and to accelerate expected growth. At age 16 years 5 months, after extraction of the maxillary first premolars and mandibular third molars, 0.022-in preadjusted edgewise brackets were placed to treat the edge-to-edge incisor relationship and minor crowding. After 13 months of treatment, the facial profile was significantly improved, and an acceptable occlusion was achieved. During the 9-year observation period after the distraction, acceptable facial growth occurred, and no relapse of the maxillary advancement was observed. However, syndrome-specific growth and methodologically induced relapse should be considered when planning a LeFort III distraction in children for the treatment of Crouzon syndrome.

    Various mechanical stimuli affect differentiation of mesoderm-derived cells such as osteoblasts or myoblasts, suggesting that adipogenesis may also be influenced by mechanical stimulation. However, effects of mechanical stimuli on adipogenesis are scarcely known. Compressive force was applied to a human preadipocyte cell line, SGBS. Levels of gene expression were estimated by real-time reverse transcription-polymerase chain reaction. The accumulation of lipids was evaluated by Sudan III or Oil Red O staining. In SGBS cells subjected to a compressive force of 226 Pa for 12 h before adipogenic induction, adipogenesis was inhibited. Compressive force immediately after adipogenic induction did not affect the adipogenesis. The expression of peroxisome proliferator-activated receptor (PPAR) gamma 2 and CCAAT/enhancer binding protein (C/EBP) a mRNA during adipogenesis was inhibited by compressive force, whereas C/EBP beta and C/EBP delta mRNA levels were unaffected. In preadipocytes, compressive force increased mRNA levels of Kruppel-like factor 2, preadipocyte factor 1, WNT10b, and cyclooxygenase-2 (COX-2) which are known as negative regulators for the PPAR gamma 2 and C/EBP alpha genes. Furthermore, a COX-2 inhibitor completely reversed the inhibition of adipogenesis by compressive force. In conclusion, compressive force inhibited adipogenesis by suppressing expression of PPAR gamma 2 and C/EBP alpha in a COX-2-dependent manner. (C) 2009. The Society for Biotechnology, Japan.

    標記アディポカイン(DDT)のヒト前駆脂肪細胞(SGBS細胞)における炎症性サイトカイン発現に及ぼす影響、脂肪細胞への分化に及ぼす影響について検討した。DDTはSGBS細胞に作用し、炎症性サイトカイン遺伝子発現および蛋白質発現・分泌を増加させた。DDTの炎症性サイトカイン発現上昇作用は、CD74発現抑制SGBS細胞およびERK阻害剤存在下では認められなかった。DDTを作用させたSGBS細胞では脂肪細胞への分化誘導時に、C/EBPβ、C/EBPδおよびPPARγ2、C/EBPαの遺伝子発現誘導が阻害され、脂肪細胞分化が抑制された。DDTは前駆脂肪細胞のCD74受容体に作用し、ERK経路を介したシグナル伝達により炎症性サイトカインの発現を促進すること、前駆脂肪細胞での脂肪細胞分化制御因子の発現誘導を阻害することで脂肪細胞分化を抑制してることが示唆された。

    口腔扁平上皮癌は顎口腔領域に発生する最も頻度の高い悪性腫瘍であり、手術、放射線、化学療法などによる集学的治療が行われてきた。いずれの治療法も年々進歩しているが、治療成績の飛躍的な向上には至っていない。予後に影響を及ぼす最大の要因は頸部リンパ節転移で、特に節外進展の有無が極めて重要となる。
    近年、腫瘍微小環境の解明がさかんに行われており、腫瘍の増殖、浸潤、転移が免疫担当細胞、線維芽細胞、新生血管を構成する血管内皮細胞、神経細胞、破骨細胞などにより制御されていることが知られつつある。リンパ節は脂肪組織に埋没していることより、本研究では口腔扁平上皮癌頸部リンパ節転移巣微小環境における脂肪細胞の役割を明らかにすることを目的とする。すなわち、口腔扁平上皮癌のリンパ節転移節外進展を脂肪細胞が助長するのか抑制するのかを明らかにした上で、空間的遺伝子発現解析技術を用いて癌細胞と脂肪細胞の相互作用を分子レベルで完全に解明する。脂肪組織はリンパ節周囲にも多く存在していることから、口腔扁平上皮癌リンパ節転移巣は脂肪組織から分泌されている各種サイトカインやエクソソーム等の影響を少なからず受けていると考えられ、脂肪組織と癌組織の相互作用を分子レベルで解明することは、節外進展のメカニズムの解明につなげることができる。
    現在、口腔扁平上皮癌症例の頸部郭清手術標本より転移リンパ節を周囲組織と伴に摘出し、組織における遺伝子発現について空間的解析を行っている。

    Adipokines (bioactive substances secreted by adipocytes) that differ in action and expression between humans and mice, as well as human-specific adipocyte differentiation mechanisms, have been reported. Therefore, conventional obesity research using mouse models does not necessarily lead directly to clinical application in humans. In this study, we used human and mouse preadipocyte cell lines to analyze the differences in gene expression during adipocyte differentiation. The results showed that various genes were differentially expressed between human and mouse. There were genes whose expression was increased specifically in humans.

    Promoter region of gene encoding D-dopachrome tautomerase (DDT), an adipokine which improves obesity-induced insulin resistance, was found to be located between 200 bp upstream and 23 bp downstream of the first methionine codon. The transcriptional activity of DDT gene was induced by oxidative stress or serum starvation in preadipocytes. Furthermore, cAMP-activated protein kinase (AMPK) was found to be involved in the transcription.

    D-dopachrome tautomerase(DDT), a novel adipokine, induces mRNA expression of IL-6 in preadipocytes. The DDT-induced IL-6 expression was found to be mediated by CD74. DDT impaired adipogenesis by inhibiting mRNA induction of adipogenic regulators during adipogenesis. Furthermore, the DDT promoter region involved the transcription in adipocytes was identified.
