Abstract
OBJECTIVE We aimed to investigate the cardiotrophin-1 (CT-1) concentrations in the serum of pregnant women with preeclampsia. METHODS This cross-sectional study was conducted with 88 pregnant women who applied to the Umraniye Training and Research Hospital Gynecology and Obstetrics Clinic between May 2022 and September 2022. The preeclampsia group consisted of 44 pregnant women diagnosed with preeclampsia, and the control group consisted of 44 healthy pregnant women matched with the preeclampsia group in terms of age and body mass index. Demographic characteristics, ultrasound and laboratory findings, perinatal outcomes, and maternal serum CT-1 concentrations were recorded. RESULTS Both groups were similar in terms of demographic features and the gestational week at blood sampling for CT-1. Preeclampsia and control groups were compared in terms of maternal serum CT-1 concentrations and no significant difference was found between the two groups (2061.4 pg/ml, 2168.5 pg/ml, respectively, p = .516). The preeclampsia group was divided into subgroups as mild and severe preeclampsia according to the severity of the disease and early-onset and late-onset preeclampsia according to the time of onset and compared with the control group in terms of maternal serum CT-1 concentration, no significant difference was found between the groups (p > .005, for all). CONCLUSION The serum CT-1 concentration of women whose pregnancy was complicated with preeclampsia was found to be similar to that of healthy controls. Although it has been shown in the literature that high serum CT-1 concentrations are associated with hypertensive heart diseases, its role in the pathophysiology of preeclampsia remains unclear.

Abstract
Background Cardiotrophin‐1 (CT‐1) is a cytokine that could induce cardiomyocytes hypertrophy and dysfunction. Plasma CT‐1 might serve as a cardiac biomarker both in diagnosis, staging, and prognostic assessment of heart failure. Methods In this study, a one‐step paramagnetic particles‐based chemiluminescence immunoassay (MPs‐CILA) for rapid and sensitive detection of plasma CT‐1 was established. Plasma samples were directly incubated with biotin‐labeled anti‐CT‐1 antibody (bio‐Ab) and acridine ester labeled anti‐CT‐1 antibody (AE‐Ab) to form sandwiched complex. The sandwiched CT‐1 was then captured by streptavidin modified paramagnetic particles (MPs‐SA) for rapid separation and signal generation. Results The proposed MPs‐CLIA presents a laudable linear relationship ranging from 7.8 pg/mL to 200 ng/mL with a detection limit of 1.0 pg/mL. The recoveries of spiked human plasma samples at low (10pg/mL), medium (100 pg/mL), and high (800 pg/mL) levels of CT‐1 were 96%, 104%, and 110% respectively. The intra‐analysis coefficient variation (CVs) of the 3 samples was 8.92%, 6.69%, and 3.54%, respectively. And the inter‐analysis coefficient variation (CVs) was 9.25%, 10.9%, and 4.3%, respectively. These results strongly indicate high sensitivity, wide linear range, acceptable precision, and applicable reproducibility of the proposed method to detect plasma level of CT‐1. Finally, Plasma CT‐1 from 140 subjects with or without chronic heart failure was analyzed to assess the clinical application of MPs‐CILA. Conclusions Noteworthily, the MPs‐CLIA method is highly automated such that it is suitable for high‐throughput detection of CT‐1 in clinical inspection.

Abstract
Central nervous system diseases remain the most challenging pathologies, with limited or even no therapeutic possibilities and a poor prognosis. This study aimed to investigate the differentiation properties of human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) transfected with recombinant adenovirus expressing enhanced green fluorescence protein cardiotrophin-1 (Adv-EGFP-CT-1) and the possible mechanisms involved. Cells were isolated, and MSC immunophenotypes were confirmed. The resulting differentiated cells treated with Adv-EGFP-CT-1 and cultured in neural induction medium (NIM) expressed higher levels of Nestin, neuronal nuclei (NeuN) and glial fibrillary acidic protein (GFAP) markers than cells in other treatments. Expression of glycoprotein 130/leukemia inhibitory factor receptor β (gp130/LiFRβ), Raf-1, phosphorylated Raf-1 (p-Raf-1), extracellular signal-regulated kinase 1/2 (ERK1/2) and phospho-ERK1/2 (p-ERK1/2) increased gradually within 72 h after transfection with Adv-EGFP-CT-1 and NIM culture. Additionally, inhibition of extracellular signal-regulated kinase kinase (MEK) abrogated expression of p-ERK1/2, Nestin, GFAP and NeuN. Thus, the ERK1/2 pathway may contribute to CT1-stimulated neural differentiation of hUCB-MSCs.

Abstract
BACKGROUND Dietary sodium affects fluctuations in blood pressure (BP) and vascular function. Cardiotrophin-1 (CT-1), a stress-induced cytokine that belongs to the interleukin 6 family, is released by cells in response to potentially harmful stresses and plays a pivotal role in congestive heart failure, hypertension and arterial stiffness. In this study, we performed a randomized trial to confirm the effects of altered salt intake on the serum CT-1 levels in humans. METHODS Forty-four subjects (18-65 years of age) were selected from a rural community in northern China. All subjects initially maintained a baseline period for 3 days, transitioned to a low-salt (LS) diet for 7 days (3.0 g/day of NaCl) and then a high-salt (HS) diet for an additional 7 days (18.0 g/day of NaCl). RESULTS For the whole group, the serum CT-1 concentrations were significantly increased in the HS period compared to those of the LS period (293.50 ± 137.70 vs. 360.40 ± 162.83 pg/mL, p = 0.040). The serum CT-1 concentrations significantly decreased from the baseline period to the LS diet (419.91 ± 123.50 to 256.49 ± 109.75 pg/mL, p < 0.01) and significantly increased from the LS to HS diet (256.49 ± 109.75 to 414.39 ± 191.21 pg/mL, p < 0.01). These changes were observed in salt-sensitive (SS) individuals but not in salt-resistant (SR) individuals. In addition, a significant positive relationship was observed between the changes in the CT-1 concentrations and systolic BP as well as the changes in the mean arterial pressure from the LS period to the HS period (r = 0.376, p = 0.012; r = 0.311, p = 0.040). The serum CT-1 concentrations were positively correlated with the 24-h urinary sodium-to-potassium (Na/K) excretion ratios during both of the LS and HS diet intervention periods in SS subjects (r = 0.621, p < 0.01), but this correlation was not evident in SR subjects (r = 0.208, p = 0.107). CONCLUSIONS Our study indicates that variations in dietary salt intake affect the serum CT-1 levels in Chinese adults.

Abstract
OBJECTIVE Fetal macrosomia is associated with cardiac hypertrophy and increased cardiovascular risk. Cardiac biomarkers may play diagnostic/prognostic role in cardiovascular disease. We tested whether cardiac biomarkers are differentially expressed in cord blood samples of full-term singleton large-for-gestational-age (LGA), as compared to appropriate-for-gestational-age (AGA) pregnancies. METHODS Cardiotrophin-1 (CT-1), Titin, pentraxin (PTX-3) and soluble CD36 (sCD36) concentrations were determined in 80 cord blood samples from a) LGA pregnancies due to maternal diabetes (n = 8), overweight/obese (n = 11), excessive weight gain (n = 7), without specific pathology (n = 14), b) AGA normal pregnancies (controls, n = 40). Neonates were classified as LGA or AGA based on customized birth weight (BW) standards. RESULTS CT-1 and Titin concentrations were higher in LGA than AGA pregnancies (p < .001 and p = .023, respectively). A subgroup analysis (in the LGA group) showed increased CT-1 concentrations only in diabetic pregnancies. PTX-3 and sCD36 concentrations were similar in LGA and AGA fetuses. In the LGA group, PTX-3 concentrations positively correlated with birth-weight (r = .416, p = .008) and respective sCD36 concentrations (r = .443, p = .004). CONCLUSION Higher Titin concentrations in LGAs possibly represent a candidate molecular mechanism underlying the association between fetal macrosomia and cardiomyocyte/diastolic dysfunction. CT-1 is up-regulated only in LGAs exposed to maternal diabetes. PTX-3 and sCD36 are probably not affected by excessive fetal growth.

Abstract
AIM Cardiotrophin-1 (CT-1) is a member of the IL-6 family of cytokines with a key role in glucose and lipid metabolism. In the current investigation, we examined the in vivo and in vitro effects of CT-1 treatment on intestinal sugar absorption in different experimental models. METHODS rCT-1 effects on α-Methyl-D-glucoside uptake were assessed in everted intestinal rings from wild-type and CT-1(-/-) mice and in Caco-2 cells. rCT-1 actions on SGLT-1 expression in brush border membrane vesicles and the identification of the potential signalling pathways involved were determined by Western blot. RESULTS In vivo administration (0.2 mg kg(-1) ) of rCT-1 caused a significant decrease on α-Methyl-D-glucoside uptake in everted intestinal rings from wild-type and CT-1(-/-) mice after short-term and long-term treatments. Similarly, in vitro treatment (1-50 ng mL(-1) ) with rCT-1 reduced α-Methyl-D-glucoside uptake in everted intestinal rings. In Caco-2 cells, rCT-1 treatment (20 ng mL(-1) , 1 and 24 h) lowered apical uptake of α-Methyl-D-glucoside in parallel with a decrease on SGLT-1 protein expression. rCT-1 promoted the phosphorylation of STAT-3 after 5 and 15 min treatment, but inhibited the activation by phosphorylation of AMPK after 30 and 60 min. Interestingly, pre-treatment with the JAK/STAT inhibitor (AG490) and with the AMPK activator (AICAR) reversed the inhibitory effects of rCT-1 on α-Methyl-D-glucoside uptake. AICAR also prevented the inhibition of SGLT-1 observed in rCT-1-treated cells. CONCLUSIONS CT-1 inhibits intestinal sugar absorption by the reduction of SGLT-1 levels through the AMPK pathway, which could also contribute to explain the hypoglycaemic and anti-obesity properties of CT-1.

Abstract
Aminoglycosides are very effective antibiotics for the treatment of severe infections, but they rank among the most frequent causes of drug-induced nephrotoxicity. Thus, prevention of aminoglycoside nephrotoxicity is an unmet therapeutic objective. Cardiotrophin-1 (CT-1), a member of the IL-6 family of cytokines, has been reported to protect the kidney against toxic and ischemic acute kidney injury (AKI). We have assessed the effect of rat CT-1 in the severity of gentamicin (G)-induced AKI. Groups of male Wistar rats received the following for 6 consecutive days: i) isotonic saline solution (group CONT), ii) G, 150mg/kg/day, i.p. (group G), iii) CT-1, 100μg/kg/day i.v. (group CT-1), or iv) G and CT-1 at the doses described above. The G group showed a manifest AKI characterized by low creatinine clearance, high plasma creatinine and urea levels, increased urinary excretion of proteins, glucose and AKI markers such as N-acetyl-glucosaminidase, neutrophil gelatinase-associated lipocalin, kidney-injury molecule-1 and T-gelsolin, increased kidney levels of CD-68, iNOS, IL-1β and TNF-α, and markedly higher histological renal damage and leukocyte infiltration than the CONT and CT-1 groups. Administration of CT-1 together with G reduced almost all of the above-described manifestations of G-induced AKI. The results of this study have potential clinical application, as CT-1 is near to being used as a drug for organ protection.

Abstract
BACKGROUND The induced pluripotent stem cell (iPSC) has shown great potential in cellular therapy of myocardial infarction (MI), while its application is hampered by the low efficiency of cardiomyocyte differentiation. The present study was designed to investigate the effects of cardiotrophin-1 (CT-1) on cardiomyocyte differentiation from mouse induced pluripotent stem cells (miPSCs) and the underlying mechanisms involved. METHODS The optimal treatment condition for cardiomyocyte differentiation from miPSCs was established with ideal concentration (10 ng/mL) and duration (from day 3 to day 14) of CT-1 administration. Up-regulated expression of cardiac specific genes that accounted for embryonic cardiogenesis was observed by quantitative RT-PCR. Elevated amount of α-myosin heavy chain (α-MHC) and cardiac troponin I (cTn I) positive cells were detected by immunofluorescence staining and flow cytometry analysis in CT-1 group. RESULTS Transmission electron microscopic analysis revealed that cells treated with CT-1 showed better organized sacromeric structure and more mitochondria, which are morphological characteristic of matured cardiomyocytes. Western blot demonstrated that CT-1 promotes cardiomyocyte differentiation from miPSCs partly via JAK2/STAT3/Pim-1 pathway as compared with control group. CONCLUSIONS These findings suggested that CT-1 could enhance the cardiomyocyte differentiation as well as the maturation of mouse induced pluripotent stem cell derived cardiomyocytes by regulating JAK2/STAT3/Pim-1signaling pathway.

Abstract
Cardiotrophin-1 (CT-1) is a member of the gp130 family of cytokines that have pleiotropic functions on different tissues and cell types. Although many effects of CT-1 have been described on the heart, there is an extensive research showing important protective effects in other organs such as liver, kidney or nervous system. Recently, several studies have pointed out that CT-1 might also play a key role in the regulation of body weight and intermediate metabolism. This paper will review many aspects of CT-1 physiological role in several organs and discuss data for consideration in therapeutic approaches.

Abstract
Riluzole is the only FDA approved drug for the treatment of amyotrophic lateral sclerosis (ALS). However, the drug affords moderate protection to ALS patients, extending life for a few months by a mechanism that remains controversial. In the presence of riluzole, astrocytes increase the production of factors protective to motor neurons. The stimulation of trophic factor production by motor neuron associated cells may contribute to riluzole's protective effect in ALS. Here, we investigated the effects of media conditioned by astrocytes and Schwann cells acutely or chronically incubated with riluzole on trophic factor-deprived motor neuron survival. While acute riluzole incubation induced CT-1 secretion by astrocytes and Schwann cells, chronic treatment stimulated a significant decrease in trophic factor production compared to untreated cultures. Accordingly, conditioned media from astrocytes and Schwann cells acutely treated with riluzole protected motor neurons from trophic factor deprivation-induced cell death. Motor neuron protection was prevented by incubation with CT-1 neutralizing antibodies. In contrast, conditioned media from astrocytes and Schwann cells chronically treated with riluzole was not protective. Acute and chronic treatment of mice with riluzole showed opposite effects on trophic factor production in spinal cord, sciatic nerve and brain. There was an increase in the production of CT-1 and GDNF in the spinal cord and CT-1 in the sciatic nerve during the first days of treatment with riluzole, but the levels dropped significantly after chronic treatment with the drug. Similar results were observed in brain for CT-1 and BDNF while there was no change in GDNF levels after riluzole treatment. Our results reveal that riluzole regulates long-lasting processes involving protein synthesis, which may be relevant for riluzole therapeutic effects. Changing the regimen of riluzole administration to favor the acute effect of the drug on trophic factor production by discontinuous long-term treatment may improve the outcome of ALS patient therapy.

Abstract
BACKGROUND Cardiotrophin-1 (CT-1) controls cardiomyogenesis of mouse embryonic stem (ES) cells. OBJECTIVES To investigate the signaling pathway underlying the action of CT-1 on cardiac cell differentiation. METHODS Protein expression was analyzed by western blot technique and cardiac areas by immunohistochemistry. Calcium, reactive oxygen species (ROS) and nitric oxide (NO) were assessed by microfluorometry using fluo-4, H2DCF, and DAF-2DA, respectively. Gene inactivation of CT-1 was achieved by siRNA technology. RESULTS CT-1 as well as its receptor gp 130 were transiently upregulated during differentiation of ES cells. Exogenous CT-1 enhanced cardiomyogenesis, increased the cardiac transcription factors MEF2c, Nkx-2.5, TEAD3 and GATA4, the cardiac proteins α-actinin, MLC2a, MYH7, MLC1a, MLC2v and HCN4 as well as vascular endothelial growth factor (VEGF), platelet-derived growth factor-BB (PDGF-BB), fibroblast growth factor-2 (FGF-2) and atrial natriuretic peptide (ANP). CT-1 downregulation by small interfering RNA (siRNA) inhibited cardiomyogenesis and decreased VEGF, PDGF-BB, FGF-2 and ANP expression. CT-1 raised intracellular calcium which was abolished by the intracellular calcium chelator BAPTA, AM and thapsigargin. Moreover, CT-1 treatment increased ROS, followed by NO generation and NOS3 activation. During ES cell differentiation CT-1 was translocated to the cell nucleus. Exogenous CT-1 induced nuclear translocation of endogenous CT-1, which was inhibited by BAPTA, the NOS inhibitor L-N(G)-Nitroarginine methyl ester (l-NAME), the radical scavenger N-(2-mercaptopropionyl)-glycine (NMPG) as well as the janus kinase 2 (JAK2) inhibitor AG490 and the PI3 kinase (PI3K) inhibitor LY294002. CONCLUSIONS Nuclear translocation of CT-1 regulates cardiomyogenesis of ES cells and involves calcium, NO, ROS as well as CT-1 regulated signaling pathways.

Abstract
BACKGROUND & AIMS Cardiotrophin-1 (CT-1) is a hepatoprotective cytokine that modulates fat and glucose metabolism in muscle and adipose tissue. Here we analyzed the changes in hepatic fat stores induced by recombinant CT-1 (rCT-1) and its therapeutic potential in non-alcoholic fatty liver disease (NAFLD). METHODS rCT-1 was administered to two murine NAFLD models: ob/ob and high fat diet-fed mice. Livers were analyzed for lipid composition and expression of genes involved in fat metabolism. We studied the effects of rCT-1 on lipogenesis and fatty acid (FA) oxidation in liver cells and the ability of dominant negative inhibitor of AMP-activated protein kinase (AMPK) to block these effects. RESULTS CT-1 was found to be upregulated in human and murine steatotic livers. In two NAFLD mouse models, treatment with rCT-1 for 10days induced a marked decrease in liver triglyceride content with augmented proportion of poly-unsaturated FA and reduction of monounsaturated species. These changes were accompanied by attenuation of inflammation and improved insulin signaling. Chronic administration of rCT-1 caused downregulation of lipogenic genes and genes involved in FA import to hepatocytes together with amelioration of ER stress, elevation of NAD(+)/NADH ratio, phosphorylation of LKB1 and AMPK, increased expression and activity of sirtuin1 (SIRT1) and upregulation of genes mediating FA oxidation. rCT-1 potently inhibited de novo lipogenesis and stimulated FA oxidation in liver cells both in vitro and in vivo. In vitro studies showed that these effects are mediated by activated AMPK. CONCLUSIONS rCT-1 resolves hepatic steatosis in obese mice by mechanisms involving AMPK activation. rCT-1 deserves consideration as a potential therapy for NAFLD.

Abstract
OBJECTIVE Cardiotrophin-1 (CT-1) shares some similarities with other cytokines, and participates in the control of energy metabolism. Higher circulating levels are observed in obese humans, but little information is gathered in weight loss (WL) programs. Therefore, we aimed to investigate the association of serum CT-1 levels with metabolic variables and the risk of developing metabolic syndrome (MetS) after a WL program in overweight/obese children. SUBJECTS AND METHODS Forty-four overweight/obese children (mean age 11.5 y; 50% males) undergoing a 10-week WL program were enrolled. Subjects were dichotomized at the median of Body Mass Index-Standard Deviation Score (BMI-SDS) change, as high and low responders after intervention. RESULTS CT-1 levels were significantly reduced (-48 fmol/mL, p=0.043) in the high responder group after the WL program. They had significantly lower body weight (-3.7 kg, p<0.001), body fat mass (-8%, p<0.001), BMI-SDS (-0.78, p<0.001) and waist circumference (-5.4 cm, p<0.001), and a significant improvement in lipid and glucose profiles (p<0.05). Interestingly, decreased CT-1 levels significantly predicted changes in total cholesterol (41%) and LDL-cholesterol (28%). Moreover, in our participants the lower the CT-1 levels, the higher the reduction in MetS risk components, after the 10-week intervention, (p-ANCOVA=0.040, p-trend=0.024). CONCLUSION We showed, for the first time, a reduction in serum CT-1 levels after a WL program and this decrease in CT-1 was strongly associated with a reduction in cholesterol levels and in MetS risk factors in overweight/obese children. Our findings may suggest that CT-1 could be an indirect marker for the diagnosis of MetS in this population.
