Introduction. Chronic inflammatory response is one of major contributors in the development of hepatocellular carcinoma (HCC). Inflammatory molecules, such as cytokines and growth factors in the circulation, can be useful in the diagnosis and prognosis of the patients. The stem cell growth factor beta (SCGFβ), a newly found protein, is a secreted sulfated glycoprotein and it functions as a growth factor for primitive hematopoietic progenitor cells. The level of SCGFβ had been reported to be elevated in several cancer types. However, there is very few or even no information on this protein in the study of HCC, even more in clinical studies. Methods. A multiplex immunoassay panel of 48 cytokines and growth factors were utilized to screen 68 sera from 29 HCC patients at pretreatment (T0), 1 month (T1), and 6 months (T6) after treatment by either radiofrequency ablation (RF) or transarterial chemoembolization (TACE). Treatment response was evaluated according to mRECIST criteria. Results. Immunoassay screening showed that the levels of IL-17, CTACK, TNFα, IL-2Rα, IL-8, and SCGFβ were different in Complete Responders (CR) and Nonresponders (NR) groups. At T0 and T1, the SCGFβ level was significantly the highest in NR (23.8 and 40.7 ng/mL, respectively), followed by early recurrence (25.4 and 25.0 ng/mL), and CR (6.7 and 5.3 ng/mL), independently from HCV, stages, and treatment type. Low basal SCGFβ level was associated with longer disease-free survival compared to high SCGFβ. Conclusion. In this study, for the first time, we demonstrate that the high level of serum SCGFβ at pre- and posttreatment is associated with HCC nonresponsiveness.

Abstract Bone marrow endothelial cells (BM ECs) have been shown to regulate HSC regeneration following myelosuppression. The role of osteolineage cells in regulating HSC regeneration remains less well understood. Here, we show that deletion of the pro-apoptotic genes, Bak and Bax, in osterix (Osx)-expressing osteoprogenitor cells promoted HSC regeneration and hematopoietic radioprotection of mice following total body irradiation (TBI). We identified Dkk1 to be enriched in the BM of radioprotected OsxCre;Bak1-/-;BaxFL/- mice and found that Bak /Bax-deficient osteolineage cells expressed increased levels of Dkk1 compared to Bax-expressing osteolineage cells (p=0.003). Treatment of irradiated BM HSCs with DKK1 in vitro significantly increased the recovery of phenotypic HSCs (p=0.0002), colony forming cells (CFCs)(p=0.003) and long-term repopulating HSCs compared to control cultures (p=0.009). Systemic administration of Dkk1 to lethally irradiated C57Bl6 mice accelerated the recovery of mature blood counts (p=0.008), BM HSCs (p=0.008) and progenitor cells (p=0.007). Furthermore, survival after lethal irradiation was markedly increased in Dkk1 treated mice (93%) compared to saline controls (27%; p=0.0004). Conversely, systemic administration of anti-Dkk1 antibody significantly delayed recovery of BM HSCs (p=0.002), peripheral white blood cells (p=0.0004), neutrophils (p<0.0001) and lymphocytes (p=0.002) in irradiated mice compared to irradiated, control mice. Dkk1 promoted HSC regeneration via suppression of reactive oxygen species (ROS) and inhibition of caspase activation in HSCs following irradiation. Dkk1 represents a novel, osteoprogenitor cell-derived paracrine factor which is necessary for normal hematopoietic regeneration following irradiation and can be therapeutically delivered to accelerate hematopoietic reconstitution.
