Abstract
The lung is an accomplished organ for gas exchanges and directly faces the external environment, consequently exposing its large epithelial surface. It is also the putative determinant organ for inducing potent immune responses, holding both innate and adaptive immune cells. The maintenance of lung homeostasis requires a crucial balance between inflammation and anti-inflammation factors, and perturbations of this stability are frequently associated with progressive and fatal respiratory diseases. Several data demonstrate the involvement of the insulin-like growth factor (IGF) system and their binding proteins (IGFBPs) in pulmonary growth, as they are specifically expressed in different lung compartments. As we will discuss extensively in the text, IGFs and IGFBPs are implicated in normal pulmonary development but also in the pathogenesis of various airway diseases and lung tumors. Among the known IGFBPs, IGFBP-6 shows an emerging role as a mediator of airway inflammation and tumor-suppressing activity in different lung tumors. In this review, we assess the current state of IGFBP-6's multiple roles in respiratory diseases, focusing on its function in the inflammation and fibrosis in respiratory tissues, together with its role in controlling different types of lung cancer.

Abstract
Primary myelofibrosis is a Ph-negative chronic myeloproliferative neoplasm characterized by bone marrow fibrosis and associated with the involvement of several pathways, in addition to bone marrow microenvironment alterations, mostly driven by the activation of the cytokine receptor/JAK2 pathway. Identification of driver mutations has led to the development of targeted therapy for myelofibrosis, contributing to reducing inflammation, although this currently does not translate into bone marrow fibrosis remission. Therefore, understanding the clear molecular cut underlying this pathology is now necessary to improve the clinical outcome of patients. The present study aims to investigate the involvement of IGFBP-6/sonic hedgehog /Toll-like receptor 4 axis in the microenvironment alterations of primary myelofibrosis. We observed a significant increase in IGFBP-6 expression levels in primary myelofibrosis patients, coupled with a reduction to near-normal levels in primary myelofibrosis patients with JAK2V617F mutation. We also found that both IGFBP-6 and purmorphamine, a SHH activator, were able to induce mesenchymal stromal cells differentiation with an up-regulation of cancer-associated fibroblasts markers. Furthermore, TLR4 signaling was also activated after IGFBP-6 and purmorphamine exposure and reverted by cyclopamine exposure, an inhibitor of the SHH pathway, confirming that SHH is involved in TLR4 activation and microenvironment alterations. In conclusion, our results suggest that the IGFBP-6/SHH/TLR4 axis is implicated in alterations of the primary myelofibrosis microenvironment and that IGFBP-6 may play a central role in activating SHH pathway during the fibrotic process.

Abstract
Colorectal cancer (CRC) is one of the most common malignant tumors in digestive tract. Previous study found close correlation between insulin-like growth factor binding proteins (IGFBPs) and occurrence of multiple tumors. This study aims to analyze the effects of IGFBP6 on the apoptosis and migration of tumor cells, and to investigate underlying mechanism. HCT-116 or SW480 cell was cultured with 1.0 mg/l, 10 mg/l and 100 mg/l IGFBP-6. MTT assay was employed to test the proliferation activity of tumor cells after differential treatment. The cell cycle of tumor cells was detected by flow cytometry, while Transwell assay was used to quantify the invasion and migration of tumor cells after IGFBP-6 intervention. In experimental group with IGFPB-6 application, the proliferation rate of HCG-116 or SW480 cells was gradually decreased with higher concentrations of IGFBP-6 (p< 0.05). The ratio of cells at G0/G1 phase was increased while S phase and G2/M phase ratio were all decreased with IGFPB-6. With further elevated concentration of IGFPB-6, there was more potency of higher G0/G1 ratio and lower S phase or G2/M phase (p< 0.05). Both invasion and migration ability of HCT-116 or SW480 cells in experimental group were decreased. With elevated IGFBP-6 concentration, cell invasion and migration were further weakened (p< 0.05).IGFBP-6 could inhibit invasion and migration of colorectal carcinoma cells possibly via inhibiting proliferation activity and arresting cell cycle of HCT-116 or SW480 cells.

Abstract
The aim of this study was to understand whether insulin-like growth factor-binding protein-6 (IGFBP-6) has functional effects on neutrophils, in particular when they cross epithelium during inflammation. We found that IGFBP-6 increased ROS production (cytofluorimetry), degranulation of primary and tertiary granules (ELISA) and transmigration through the epithelial monolayer. No priming by IGFBP-6 on neutrophils stimulated by either PMA or fMLP was observed. IGFBP-6 is an agonist of neutrophils' functions, most likely when these cells have been already activated by other stimuli.

Abstract
The insulin-like growth factor (IGF) system is linked to CNS pathological states. The functions of IGFs are modulated by a family of binding proteins termed insulin-like growth factor binding proteins (IGFBPs). Here, we demonstrate that IGFBP-6 may be associated with neuronal apoptosis in the processes of intracerebral hemorrhage (ICH). We obtained a significant upregulation of IGFBP-6 in neurons adjacent to the hematoma following ICH with the results of Western blot, immunohistochemistry, and immunofluorescence. Increasing IGFBP-6 level was found to be accompanied by the upregulation of Bax, Bcl-2, and active caspase-3. Besides, IGFBP-6 co-localized well with active caspase-3 in neurons, indicating its potential role in neuronal apoptosis. Knocking down IGFBP-6 by RNA-interference in PC12 cells reduced active caspase-3 expression. Thus, IGFBP-6 may play a role in promoting the brain secondary damage following ICH.

Abstract
The syndrome of nonislet cell tumor induced hypoglycemia (NICTH) represent extreme cases of excessive expression and production of incompletely processed high-molecular-mass pro-IGF-II forms (big IGF-II) by an often large tumor. Tumor-derived big IGF-II is responsible for enhanced insulin-like effects in the body through complicated mechanisms, leading to hypoglycemia. Case studies on NICTH usually focus on measurements of diagnostic parameters in the circulation of patients. Some studies have also reported on qualitative immunohistochemical analysis of tumor tissue, in particular with respect to the expression of IGF-II at the mRNA or protein level. However, quantitative data on the concentrations of IGFs and IGFBPs in tumor specimen causing NICTH, in relation to their corresponding plasma levels are lacking. Such an analysis would provide an estimate of the total potential of (big) IGF-II retained by the tumor and more insight in the relative levels of different IGFBPs and their origin in the circulation, that is, systemically induced by tumor related factors or directly tumor-derived. Here we investigated quantitatively the levels of IGFs and IGFBPs in a large, 1.76 kg weighing, solitary fibrous tumor from a typical case of NICTH using highly specific immunometric assays. Besides a high level of big IGF-II, patient's plasma also contained increased levels of both IGFBP-2 and -6 which declined after removal of the tumor. These IGFBPs have a higher affinity for (pro-) IGF-II than IGF-I and exhibit intrinsic IGF-independent bioactivities. Tumor tissue contained high amounts of big IGF-II and IGFBP-6, exceeding that in patient's circulation many-fold. A relatively low tumor content of IGFBP-2 was found suggesting that the preoperative high levels in plasma were attributable to systemic mechanisms. The background literature and possible implications of these findings are briefly discussed. Based on the present results we postulate that tumor tissue is not the source of the elevated levels of IGFBP-2 often seen in NICTH patients. Large tumors that cause NICTH can produce IGFBP-6 leading to enhanced levels of this IGFBP in the circulation. Hence, the measurement of IGFBP-6 in plasma may serve as an additional marker of this disease pattern.
