简介

Serine/threonine-protein kinase that plays a role in many biological processes such as fatty acid oxidation, autophagy, immune response or glucose metabolism (PubMed:23322770, PubMed:26983400). Phosphorylates 'Ser-794' of IRS1 in insulin-stimulated adipocytes, potentially modulating the efficiency of insulin signal transduction. Inhibits CREB activity by phosphorylating and repressing TORCs, the CREB-specific coactivators (PubMed:15454081). Phosphorylates EP300 and thus inhibits its histone acetyltransferase activity (PubMed:21084751, PubMed:26983400). In turn, regulates the DNA-binding ability of several transcription factors such as PPARA or MLXIPL (PubMed:21084751, PubMed:26983400). Also plays a role in thymic T-cell development (By similarity).

AbstractAs an important kinase that maintains metabolic homeostasis, salt‐induced kinase 2 (SIK2) inhibits adipogenesis in adipocytes and regulates mammalian glucose metabolism. Excessive lipid accumulation can lead to an inflammatory response, and SIK2 also controls the expression of inflammatory cytokines. However, the precise mechanisms and interconnections through which SIK2 modulates these processes remain incompletely understood. The present study explores the regulatory role of SIK2 in hepatic glucose and lipid metabolism and lipogenesis‐induced inflammatory response of Larimichthys crocea. We found that palmitic acid or glucose reduces sik2 mRNA expression, while its expression increases in response to insulin. Further, SIK2 reduces glucose content by inhibiting gluconeogenesis and activating insulin signaling pathways. Meanwhile, SIK2 overexpression decreases lipogenesis‐related gene expression and increases lipolysis‐related gene expression, alleviating hepatocyte lipid accumulation. Due to sequence conservation, SIK2 mutants are constructed. Only the T176A mutant weakens the inhibition of wt‐SIK2 on the acetyl‐CoA carboxylase 1 (ACC1) promoter through cyclic AMP‐responsive element‐binding protein (CREB). It increases the expression of CREB‐regulated transcription coactivator 2 (CRTC2) in the nucleus. Then, ACC1 inhibition attenuates the inflammatory response. SIK2 alleviates the inflammatory response by reducing pro‐inflammatory cytokines expression and inactivating the mitogen‐activated protein kinase (MAPK) pathway. Furthermore, similar results were obtained by inhibiting SIK2 in vivo. Overall, this study explores the role of SIK2 in hepatic glucose and lipid metabolism and lipogenesis‐induced inflammatory response in fish for the first time, which provides insights into the functional protection of SIK2 in vertebrate evolution and may serve as a target for the treatment of nutritional and immune disorders.

ABSTRACTObjectivesAutophagic impairment has been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Salt‐inducible kinase 2 (SIK2), a member of the AMP‐activated protein kinase (AMPK) family widely expressed in the central nervous system, plays critical roles in neuronal survival, neurogenesis, and the regulation of autophagy. This study aims to investigate the effects and underlying mechanisms of SIK2 in the pathogenesis of ALS.MethodsIn our work, we used both in vivo and in vitro models of ALS to study the effect of SIK2. Protein and RNA levels were assessed by Western blot, RT‐qPCR, immunofluorescence, and immunohistochemistry. Cell viability and apoptosis were evaluated using CCK‐8 assay and flow cytometry. Transmission electron microscopy was employed to examine autophagic vacuoles. Additionally, lentivirus particles carrying shRNA targeting SIK2 (sh‐SIK2) were injected into the lateral ventricle of ALS mice at 60 days of age. Motor performance was evaluated by the rotarod test.ResultsWe observed that increased expression of SIK2 significantly contributed to the degeneration of motor neurons in both the cellular model and the hSOD1G93A transgenic mice model of ALS. SIK2 knockdown enhanced neuronal survival and restored mTORC1 activity. Furthermore, SIK2 suppression facilitated the clearance of mutant SOD1 accumulation by activating autophagic flux and enhancing lysosomal acidification. Conversely, SIK2 overexpression impaired mTORC1 activity, exacerbating autophagy dysfunction by inhibiting lysosomal function, and ultimately led to motor neuron degeneration. In vivo, SIK2 deficiency delayed disease onset and extended the lifespan of ALS mice by enhancing autophagy‐mediated clearance of mutant SOD1 aggregates.ConclusionsOur findings reveal that SIK2 regulates autophagic flux by modulating lysosomal acidification, thereby influencing the degradation of mutant SOD1 aggregates. SIK2 suppression enhances autophagy‐mediated clearance of toxic protein aggregates and protects motor neurons, highlighting its potential as a therapeutic target for ALS.

Pharmacol Res：科学家找到了与肝癌患者生存率显著相关的靶点

LKB1（肝激酶B1）信号通路已被证明在调节能量稳态、极性和代谢等关键细胞过程中发挥着不可或缺的作用。 LKB1（肝激酶B1）信号通路已被证明在调节能量稳态、极性和代谢等关键细胞过程中发挥着不可或缺的作用。早期研究将LKB1从人类胎肝中分离出来，发现它具有抑癌作用，其突变与遗传性癌症障碍Peutz-Jeghers综合征有关。进一步的研究确定LKB1是一种主激酶，它通过与CAB39和STRAD支架作用来磷酸化16种下游激酶（AMPK1/2、MARK1/2/3/4、NUAK1/2、SIK1/2/3、BRSK1/2和SNRK），从而对细胞生物学产生影响。尽管LKB1信号轴的部分，如AMPK途径，已经得到了很好的研究和报道，但LKB1直接下游的许多激酶仍然没有得到充分的表征。图片来源：https://doi.org/10.1016/j.phrs.2023.106757 近日，来自杜兰大学的研究者们在Pharmacol Res.杂志上发表了题为“LKB1 Signaling and Patient Survival Outcomes in Hepatocellular Carcinoma”的文章，该研究表明LKB1下游的许多激酶对肝癌患者生存率有统计学显著影响。 LKB1、STRAD和CAB39形成一种复合物，其功能是磷酸化和激活下游信号通路。有趣的是，所有复杂成员的mRNA水平都与患者生存率呈正相关，但只有STRADß和CAB39L具有统计学意义。这可以通过LKB1在恶性细胞细胞谢改变中的作用来解释。除了支架蛋白外，具有统计学正生存相关性的下游LKB1激酶是SIK1、SIK2和SNRK。 GEPIA的其他生物信息学分析还发现，与正常肝组织相比，癌症中SIK1的表达减少了2倍。通过蛋白质印迹进行的蛋白质表达分析未能产生任何SIK1条带，进一步支持SIK1在肝细胞癌中的肿瘤抑制作用。此外，SIK3的患者生存风险比范围为0.52-1.03。该值被加权为正相关，但在统计上不显著。尽管如此，似乎与正生存率有着趋势性的相关性。肝细胞癌细胞系的蛋白质印迹分析显示高表达水平（Huh7和Hep3B）和无表达水平（HepG2和PLC/PRF/5）之间存在明显的二分法，表明存在肝细胞癌亚型的可能性。相反，AMPKα2、MARK2、BRSK1和BRSK2与肝细胞癌的不良生存结果具有统计学显著相关性。GEPIA分析表明，AMPKα2、BRSK1和BRSK2在正常肝组织中低表达。与正常组织相比，肝脏肿瘤中的AMPKα2和BRSK1分别扩增了5倍和2倍。免疫印迹分析显示癌症细胞中AMPKα2和MARK2的高水平表达。此外，AMPKα2、MARK2和BRSK2已被证明分别在肝细胞癌、非小细胞肺癌和胰腺癌的营养缺乏条件下通过Warburg效应促进肿瘤活性和生长。影响肝癌患者生存率的下游激酶。图片来源：https://doi.org/10.1016/j.phrs.2023.106757 综上所述，STRADß、CAB39L、AMPKα、MARK2、SIK1、SIK2、BRSK1、BRSK2和SNRK的表达对肝癌患者生存率有统计学显著影响。该综述旨在解决下游LKB1激酶在知识方面的差距，并为他们在肝细胞癌发生中的潜在作用奠定基础。（生物谷 Bioon.com）参考文献 Khoa Nguyen et al.

Galapagos goes 0-for-3 on inflammation program as it cuts an early-stage candidate

Galapagos has cut anti-inflammatory drug candidate GLPG4399 following the completion of an early-stage healthy volunteer trial, according to its 2022 annual report released Thursday afternoon. GLPG4399 was a SIK3 inhibitor, one in a line of such salt-inducible kinase (SIK) inhibitors that Galapagos has been trying to develop for inflammatory diseases like rheumatoid arthritis and ulcerative colitis. Originally, the biotech had been planning to move the drug forward in a study with rheumatoid arthritis patients in the middle of this year, but now it’s halting the program and going back to search for new SIK inhibitors. “Medicinal chemistry activities to identify SIK inhibitors with improved pharmacology continues,” Galapagos noted briefly in its press release. GLPG4399 was the third SIK inhibitor Galapagos brought out of the clinic — all part of a franchise Galapagos dubbed Toledo. The first candidate, GLPG3312, similarly only made it through healthy volunteer studies before Galapagos scrapped it. The second, GLPG3970, disappointed in Phase II trials in ulcerative colitis and rheumatoid arthritis, and though it showed some signs of efficacy in psoriasis, Galapagos opted to toss that candidate as well. The small pipeline prune comes after Galapagos laid off 200 staffers and discontinued work on its fibrosis and kidney disease programs, cuts that followed a long string of setbacks at the biotech. In December, Galapagos also announced that its chief business officer André Hoekema and chief medical officer Walid Abi-Saab are retiring, though the latter is remaining with the company until the end of May. Galapagos shares $GLPG fell almost 8% after the markets opened Friday. The biotech did not immediately return request for comment.

PNAS：新型口服化合物或有望预防并治疗骨质疏松症

来自麻省总医院等机构的科学家们通过研究识别出了一种有潜力的化合物，其或能影响甲状旁腺素信号通路的组分，当给予小鼠口服时，还会增加机体的骨质量。甲状旁腺素（parathyroid hormone）能刺激骨形成，该激素的类似物也用于治疗骨质疏松症（osteoporosis）患者，然而这些药物只有在每天注射的情况下才会有效。近日，一篇发表在国际杂志Proceedings of the National Academy of Sciences上题为“Structure-based design of selective, orally available salt-inducible kinase inhibitors that stimulate bone formation in mice”的研究报告中，来自麻省总医院等机构的科学家们通过研究识别出了一种有潜力的化合物，其或能影响甲状旁腺素信号通路的组分，当给予小鼠口服时，还会增加机体的骨质量。这一研究发现或有望帮助研究人员开发出预防并治疗骨质疏松症的新型更为方便的药物。医学博士Marc Wein说道，目前并没有针对骨质疏松症的口服药物来刺激骨形成，于是我们就试图理解正常情况下能控制骨产生的通路，从而开发出诸如此类药物。参与甲状旁腺素的特殊通路或许会抑制盐诱导激酶2和3（SIK2和SIK3），这两种酶类在调节骨生长和重塑方面扮演着重要角色。新型口服化合物或有望预防并治疗骨质疏松症。图片来源：Proceedings of the National Academy of Sciences (2022). DOI:10.1073/pnas.2214396119 文章中，研究者Wein及其同事开发了针对这些酶类的新型结构模型，随后利用包括基于结构的药物设计和迭代药物化学等先进方法识别出了能潜在抑制SIK2和SIK3酶类功能的特殊化合物；当给予细胞（尤其是给予小鼠时）时，这种名为SK-124的化合物或许具有甲状旁腺素样的效应；在小鼠机体中，连续三周每天口服治疗一次或能增加机体血液中钙离子和维生素D的水平，同时还会增强机体的骨形成和骨量，同时也并不会产生短期的毒性效应。研究者指出，基于这些研究发现，我们提出，诸如SK-124等小分子或许能代表新一代的口服骨构建疗法来治疗骨质疏松症；目前研究人员正在与Radius Health公司合作，希望能进一步优化并开发治疗骨质疏松症患者的新型疗法。综上，本文研究结果表明，口服SIK2/SIK3抑制剂SK-124作为疗法进行治疗时或许会对机体骨骼和矿物质代谢产生甲状旁腺素样的效应。（生物谷Bioon.com）原始出处： Tadatoshi Sato,Christian D.
