Abstract
BACKGROUND Cell differentiation agent II (CDA-II) exhibits potent anti-proliferative and apoptosis-inducing properties against a variety of cancer cells. However, its mechanism of action in chronic myeloid leukemia (CML) remains unclear. METHODS Cell counting Kit 8 (CCK-8) and flow cytometry were used to investigate the effects of CDA-II on the biological characteristics of K562 cells. Gene (mRNA and lncRNA) expression profiles were analyzed by bioinformatics to screen differentially expressed genes and to perform enrichment analysis. The Pearson correlation coefficients of lncRNAs and mRNAs were calculated using gene expression values, and a lncRNA/mRNA co-expression network was constructed. The MCODE and cytoHubba plugins were used to analyze the co-expression network. RESULTS The Results, derived from CCK-8 and flow cytometry, indicated that CDA-II exerts dual effects on K562 cells: it inhibits their proliferation and induces apoptosis. From bioinformatics analysis, we identified 316 mRNAs and 32 lncRNAs. These mRNAs were predominantly related to the meiotic cell cycle, DNA methylation, transporter complex and peptidase regulator activity, complement and coagulation cascades, protein digestion and absorption, and cell adhesion molecule signaling pathways. The co-expression network comprised of 163 lncRNA/mRNA interaction pairs. Notably, our analysis results implicated clustered histone gene families and five lncRNAs in the biological effects of CDA-II on K562 cells. CONCLUSION This study highlights the hub gene and lncRNA/mRNA co-expression network as crucial elements in the context of CDA-II treatment of CML. This insight not only enriches our understanding of CDA-II's mechanism of action but also might provide valuable clues for subsequent experimental studies of CDA-II, and potentially contribute to the discovery of new therapeutic targets for CML.

Abstract
OBJECTIVE To investigate the potential neuroprotective effect of human urine extract cell differentiation agent 2 (CDA-2) by the model of serum deprivation-induced apoptosis of PC12 cells and study the underlying molecular mechanisms. METHODS Apoptosis of PC12 cells was induced by serum deprivation. CDA-2 at doses of 0.5-4 mg/mL was used to treat the serum-deprived PC12 cells. The cellular viability was measured by sulforhodamine B binding assay and the cell apoptosis was determined by flow cytometer. Western blot was used to analyze the expression of differentiation markers and activity of extracellular signal-regulated kinase (ERK). The cellular morphology was examined under an inverted microscope. RESULTS CDA-2 inhibited apoptotic cell death of serum-deprived PC12 cells in a dose-dependent manner. Expression of low- and mid-sized neurofilaments was observed in serum-deprived PC12 cells treated with CDA-2 or nerve growth factor (NGF). However, CDA-2 did not induce proliferation of these cells like NGF. The morphology of CDA-2 treated cells was changed from rounded to neuron-like flat polygonal shape in contrast to the extensive neurite outgrowth induced by NGF. CDA-2 transiently induced the phosphorylation of ERK in serum deprived-PC12 cells and the expression of neurofilaments induced by CDA-2 was attenuated by mitogen-activated protein/extracellular signal-regulated kinase kinase (MEK) inhibitor PD98059. CONCLUSIONS Human urine extract CDA-2 showed a potential neuroprotective activity which may correlate with ERK activation and differentiation induction.

Abstract
Cell differentiation agent II (CDA‑II) is a DNA methyltransferase inhibitor isolated from healthy human urine. In the present study, the antitumor activity of CDA‑II on human multiple myeloma (MM) cell lines via the mitochondrial pathway was first revealed. The human MM cell lines were exposed to CDA‑II. Cytotoxicity, caspase activation, apoptosis and the effects on the mitochondrial pathway were assessed. CDA‑Ⅱ was capable of decreasing the depolarized mitochondrial membranes and activating caspase‑3 and ‑9 and poly (ADP‑ribose) polymerase in MM cells treated with CDA‑II. CDA‑II induced caspase‑dependent cell death accompanied by a significant decrease in X-linked inhibitor of apoptosis protein (XIAP), survivin and Mcl‑1 levels. The caspase‑3 inhibitor, Z‑DEVD‑FMK, inhibited CDA‑II‑induced apoptosis. CDA‑II potently increased the Bax levels, decreased the Bcl‑2/Bax ratio and decreased the expression of the downstream targets of NF‑κB. In conclusion, the results of the present study demonstrated that CDA‑II treatment leads to the inhibition of p65 nuclear localization and potently induces caspase‑dependent apoptosis in MM cells mediated through the mitochondrial pathway at low nanomolar concentrations. These results indicate that CDA‑II is a novel inhibitor of NF‑κB activity, with notable antimyeloma efficacy. This study provides a rationale for the clinical investigation of CDA‑Ⅱ in human MM.

Abstract
The aberrant expression of cyclin-dependent kinase-4 (CDK4) has previously been observed in human brain glioma. Furthermore, it is observed that up-regulation of CDK4 is associated with therapy resistance and relapse. However, the mechanisms behind these phenomena remain unclear. Here, we demonstrated that elevated CDK4 expression is correlated with poor prognosis in glioma after radiotherapy and that CDK4 knockdown conferred radiosensitivity in glioma cell lines. CDK4 was identified as potential downstream target of miR-124 through bioinformatics analysis and dual-firefly luciferase reporter assay. Furthermore, restoration of miR-124 could confer radiosensitivity. Cell differentiation agent-2 (CDA-2) mimicked the effect of miR-124 restoration and CDK4 knockdown, and sensitized xenografts to radiation in an animal model. Our findings demonstrated for the first time that CDK4 was a downstream target of miR-124 and that CDA-2 could radiosensitize Glioblastoma multiforme cells through the MiR-124-CDK4 axis.

Abstract
CDA-2 (cell differentiation agent 2), a urinary preparation, has potent anti- proliferative and pro-apoptotic properties in cancer cells. However, the mechanisms of tumor inhibitory action of CDA-2 are far from clear, and especially there was no report on lung cancer. Here we demonstrate that CDA-2 and its main component phenylacetylglutamine (PG) reduce the metastatic lung tumor growth, and increases survival time after inoculation with Lewis lung carcinoma (LLC) cells in a dose-dependent manner in C57BL6 mice. Proliferative program analysis in cancer cells revealed a fundamental impact of CDA-2 and PG on proliferation and apoptosis, including Bcl-2, Bcl-XL, cIAP1, Survivin, PCNA, Ki-67 proteins and TUNEL assays. CDA-2 and PG significantly reduced NF-κB DNA-binding activity in lung cancer cells and in alveolar macrophages of tumor bearing mice and especially decreased the release of inflammatory factors including TNFα, IL-6, and KC. Furthermore, CDA-2 and PG decrease the expressions of TLR2, TLR6, and CD14, but not TLR1, TLR3, TLR4, and TLR9 in bone-marrow-derived macrophages (BMDM) of mice stimulated by LLC-conditioned medium (LLC-CM). Over-expressing TLR2 in BMDM prevented CDA-2 and PG from inhibiting NF-κB activation, as well as induction of TNFα and IL-6. TLR2:TLR6 complexes mediate the effect of NF-κB inactivation by CDA-2. In conclusion, CDA-2 potently inhibits lung tumor development by reduction of the inflammation in lung through suppression of NF-κB activation in myeloid cells, associating with modulation of TLR2 signaling.

Abstract
Cell differentiation agent-2 (CDA-2) is an extraction from healthy human urine consisting of primary organic acids and peptides, and it has been demonstrated to inhibit growth and induce differentiation in glioma and other cell lines. But the mechanism of CDA-2 remains unclear. In this study, we demonstrated that CDA-2 inhibited cell growth and induced differentiation of glioma cells, accompanied with decreased expression of SLUG, Twist and Vimentin in both SWO-38 and U251 cell lines. Overexpression of SLUG or Twist greatly eliminated the efficiency of CDA-2 in inducing differentiation. Further study showed that CDA-2 treatment resulted in great changed microRNAs (miRNAs) detected by quantitative PCR, in which miR-124 was one of the most changed miRNAs and its level was increased by fourfold. The result of miRNA target prediction showed that miR-124 could regulate hundreds of genes which were relative to cell differentiation, such as SLUG, Vimentin, actin cytoskeleton, focal adhesion, tight junction. Inhibition of miR-124 up-regulated SLUG, Twist and Vimentin proteins, and partly eliminated the function of CDA-2 on these mesenchymal markers. Our findings demonstrated for the first time that CDA-2 induced cell differentiation through suppressing Twist and SLUG via miR-124 in glioma cells.

Abstract
Glioma remains one of the most lethal human tumors in spite of the progress in radiotherapy, chemotherapy, and surgical techniques. Cell differentiation agent-2 (CDA-2) is an extraction from healthy human urine consisting of primary organic acids and peptides, and it has been demonstrated to inhibit growth and induce differentiation in glioma and other cell lines. However, the mechanism remains unclear. Peroxisome proliferator-activated receptors (PPARs) are members of the nuclear hormone receptors (NHRs) which are involved in cellular differentiation and proliferation. In this study, we investigated if CDA-2 induced differentiation of SWO-38 glioma cells is mediated by PPARgamma. CDA-2 induced differentiation of SWO-38 cells was characterized by typical morphological changes, increased expression of GFAP, inhibition of proliferation and G(0)/G(1) cell cycle arrest. CDA-2 also triggered up-regulation of PPARgamma, GFAP and PTEN protein and a reduction of COX-2 protein. However, the effects of CDA-2 on SWO-38 cells could be partly reversed by GW9662, an irreversible PPARgamma antagonist. Our investigation demonstrated that CDA-2 could be a potential drug for tumor differentiation therapy, and activation of the PPARgamma pathway might be a crucial factor in glioma differentiation induced by CDA-2.

Abstract
CDA-II (cell differentiation agent II) was a urinary preparation, isolated from healthy human urine. We determined the anticancer activity of CDA-II using human acute myeloid leukemia (AML) cell lines, K562, Kasumi-1 and KG-1. An in vitro cytotoxicity assay showed that CDA-II exhibited growth arrest in leukemic cells, while it did not induce cytotoxicity in normal peripheral blood mononuclear cells (PBMCs). In vivo studies using the Kasumi-1 xenografted SCID mouse model showed tumor inhibition rate were increased and the survival time were prolonged in a dose-dependent manner, without any significant toxicity on mice body. Depolarized mitochondrial membranes and the activation of caspase-3, 9 as well as PARP were found in leukemic cells treated with CDA-II for 6-24h. We further found NF-kappaB nuclear translocation were prevented by CDA-II treatment, which therefore inactivated NF-kappaB and down-regulated its target genes expression, including Bcl-2/Bax ratio, Mcl-1 and XIAP. The caspase-3 inhibitor Z-DEVD-FMK inhibited CDA-II-induced apoptosis and CDA-II combined with NF-kappaB inhibitor PDTC significantly increased the apoptotic rate of leukemic cells. We concluded that CDA-II potently induced caspase-dependent leukemia-specific apoptosis in leukemic cells mediated through inactivation of NF-kappaB, involving in Bcl-2 family and XIAP, which has no cytotoxicity on normal cells.

Abstract
AIM The aim of this study was to investigate the antitumoral activity of human urine extract against myelodysplastic syndrome (MDS)-derived MUTZ-1 cells in vitro and in vivo. METHODS The MDS-refractory anemia with excess of blasts (RAEB)-derived MUTZ-1 cell line was used to examine the effects of a human urine preparation, CDA-2, on the induction of growth arrest and apoptosis. Apoptotic proteins, including caspase family, Bcl-2 family, the inhibitor of apoptosis protein (IAP) family, and the FLICE-like inhibitory protein (FLIP), as well as cell cycle-associated proteins were studied. The phosphoinositide 3 kinase (PI3K)/Akt survival signaling pathway and the NF-kappaB pathway were also examined. The caspase-3 inhibitor Z-DEVD-fmk was used to examine the involvement of caspase-3 and poly (ADP-ribose) polymerase (PARP). PI3K inhibitor LY294002 was used to examine the involvement of the PI3K/Akt signaling pathway in this apoptosis-inducing effect. MUTZ-1 cell xenografted serious combined immunodeficiency disease mice were used for the in vivo study. RESULTS We found that CDA-2 could induce growth arrest and apoptosis of MUTZ-1 cells in vitro and in vivo. The main mechanisms were related to the inhibition of PI3Kp110alpha expression at the transcriptional level, which inactivated the phosphorylation of Akt involving the prevention NF-kappaB phosphorylation and nuclear translocation, the downregulation of the IAP family and FLIPL protein, and the dephosphorylation of the Bad protein, which then triggered the activation of the caspase cascades. This phenomenon could be inhibited by the PI3K inhibitor LY294002 and caspase-3 inhibitor Z-DEVD-fmk. CONCLUSION Our results demonstrate the presence of active components in the human urine extract that can induce the growth arrest and apoptosis of MDS-RAEB-derived MUTZ-1 cells and may involve the PI3K/Akt signaling pathway in a caspase-3-dependent manner. This may provide new insights for the treatment of high-risk MDS.
