[PMID: 38375561 DOI: 10.1002/biot.202300338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 11/25/2023] [Accepted: 12/13/2023] [Indexed: 02/21/2024]
Abstract
Chinese hamster ovary (CHO) cells are widely used to produce complex biopharmaceuticals. Improving their productivity is necessary to fulfill the growing demand for such products. One way to enhance productivity is by cultivating cells at high densities, but inhibitory by-products, such as metabolite derivatives from amino acid degradation, can hinder achieving high cell densities. This research examines the impact of these inhibitory by-products on high-density cultures. We cultured X1 and X2 CHO cell lines in a small-scale semi-perfusion system and introduced a mix of inhibitory by-products on day 10. The X1 and X2 cell lines were chosen for their varied responses to the by-products; X2 was susceptible, while X1 survived. Proteomics revealed that the X2 cell line presented changes in the proteins linked to apoptosis regulation, cell building block synthesis, cell growth, DNA repair, and energy metabolism. We later used the AB cell line, an apoptosis-resistant cell line, to validate the results. AB behaved similar to X1 under stress. We confirmed the activation of apoptosis in X2 using a caspase assay. This research provides insights into the mechanisms of cell death triggered by inhibitory by-products and can guide the optimization of CHO cell culture for biopharmaceutical manufacturing.

Abstract
Cytokine-induced apoptosis inhibitor 1 (CIAPIN1) protein is widely expressed in the brain and it is known that this protein is involved in cell survival including dopaminergic neuronal cells. Oxidative stress is known as one of the major causes of degenerative diseases including ischemia. In this study, we investigated the effect of CIAPIN1 protein on hippocampal neuronal (HT-22) cell damage induced by hydrogen peroxide (H2O2) and in an animal model of ischemia using Tat-CIAPIN1 fusion protein which can transduce into cells. Tat-CIAPIN1 protein transduced into HT-22 cells and significantly inhibited cell death, DNA fragmentation, and reactive oxygen species (ROS) generation. Also, Tat-CIAPIN1 protein enhances cell survival via the regulation of Akt, MAPK, NF-κB and apoptotic signaling pathways in the H2O2 treated cells. In an ischemic animal model, Tat-CIAPIN1 protein transduced into the brain and protected neuronal cell death of hippocampal CA1 region induced by ischemic insult. In conclusion, we demonstrated that Tat-CIAPIN1 protein has protective effects against hippocampal neuronal cell damage induced by ischemic injury, suggesting that Tat-CIAPIN1 protein may provide a potential therapeutic agent for ischemia.

Abstract
Although dCTP pyrophosphatase 1 (DCTPP1) has been reported to be associated with poor clinical outcomes in various cancers, whether it plays an important role in prostate cancer (PCa) remains unclear. In this study, an immunohistochemical assay showed the protein expression level of DCTPP1 was significantly higher in PCa tissues than in non-cancerous tissues. Moreover, DCTPP1 was upregulated at both protein and mRNA levels in the PCa tissues from high Gleason score patients versus low Gleason score patients. The analysis of The Cancer Genome Atlas RNA-seq data suggested that upregulation of DCTPP1 was inversely correlated with biochemical recurrence free survival and overall survival. The roles of DCTPP1 in tumor progression and autophagy were further validated through cells invasion, migration, apoptosis and proliferation assays in vitro, as well as EMT and autophagy assays in vivo. Advanced bioinformatics analysis identified the evidence supporting the promotional role of DCTPP1 in tumor progression associated with autophagy. We conclude that DCTPP1 may play an important role in PCa progression associated with high autophagy. Overexpression of DCTPP1 may server as a biomarker for predicting poor BCR-free survival and overall survival for PCa patients.

Abstract
Cytokine-induced apoptosis inhibitor 1 (CIAPIN1), originally termed anamorsin, is an anti-apoptotic molecule that acts as a downstream effector of the receptor tyrosine kinase-Ras signaling pathway. Overexpression of CIAPIN1 contributes to multidrug resistance (MDR) and microRNA (miR)-143 is typically considered a tumor suppressor in breast cancer. The present study aimed to evaluate the therapeutic potential of miR-143 as a treatment for drug-resistant breast cancer via the downregulation of CIAPIN1 in vitro. The expression levels of miR-143 were measured using quantitative polymerase chain reaction and the expression levels of CIAPIN1 were detected via western blot analysis. Bioinformatic analyses was additionally conducted to search for miR-143, which may potentially target CIAPIN1. Luciferase reporter plasmids were created and used to verify direct targeting. In addition, Taxol-induced drug-resistant (TDR) breast cancer cell proliferation was evaluated using the Cell Counting Kit-8 assay in vitro. The present study identified an inverse association between miR-143 and CIAPIN1 protein expression levels in breast cancer MCF-7, MDA-MB-231 and MDA-MB-453 TDR cells. Specific targeting sites for miR-143 in the 3′-untranslated region of the CIAPIN1 gene were identified, which exhibit the ability to regulate CIAPIN1 expression. It was revealed that the repression of CIAPIN1 via miR-143 suppressed the proliferation of breast cancer TDR cells. The findings of the present study verified the role of miR-143 as a tumor suppressor in breast cancer MDR via inhibition of CIAPIN1 translation.

Glucose Starvation Alters Heat Shock Response, Leading to Death of Wild Type Cells and Survival of MAP Kinase Signaling Mutant. PLoS One 2016; 11:e0165980.

Abstract
A moderate heat shock induces Neurospora crassa to synthesize large quantities of heat shock proteins that are protective against higher, otherwise lethal temperatures. However, wild type cells do not survive when carbohydrate deprivation is added to heat shock. In contrast, a mutant strain defective in a stress-activated protein kinase does survive the combined stresses. In order to understand the basis for this difference in survival, we have determined the relative levels of detected proteins in the mutant and wild type strain during dual stress, and we have identified gene transcripts in both strains whose quantities change in response to heat shock or dual stress. These data and supportive experimental evidence point to reasons for survival of the mutant strain. By using alternative respiratory mechanisms, these cells experience less of the oxidative stress that proves damaging to wild type cells. Of central importance, mutant cells recycle limited resources during dual stress by undergoing autophagy, a process that we find utilized by both wild type and mutant cells during heat shock. Evidence points to inappropriate activation of TORC1, the central metabolic regulator, in wild type cells during dual stress, based upon behavior of an additional signaling mutant and inhibitor studies.

Abstract
CIAPIN1 (cytokine-induced apoptosis inhibitor 1) was recently identified as an essential downstream effector of the Ras signaling pathway. However, its potential role in regulating myeloid leukemia cells sensitivity to Imatinib remains unclear. In this study, we found depletion of CIAPIN1 inhibited proliferation and triggered more apoptosis of K562CML (chronic myeloid leukemia) cells with or without Imatinib treatment. Meanwhile, CIAPIN1 depletion decreased ERK5 phosphorylation and NF-κB activity. Importantly, treating CIAPIN1-depleted K562 cells with ERK5 signaling pathway specific inhibitor, XMD8-92, further inhibited proliferation and promoted apoptosis with or without Imatinib treatment. Treatment with the NF-κB specific inhibitor, Bay 11-7082, induced nearly the same inhibition of proliferation and promotion of apoptosis conferred by CIAPIN1 depletion as was observed with XMD8-92 treatment. Further, XMD8-92 and Bay 11-7082 synergistically inhibited proliferation and promoted apoptosis of CIAPIN1-depleted K562 cells with or without Imatinib treatment. The nude mice transplantation model was also performed to confirm the enhanced sensitivity of CIAPIN1-depleted K562 cells to Imatinib. Thus, our results provided a potential management by which CIAPIN1 knock-down might have a crucial impact on enhancing sensitivity of K562 cells to Imatinib in the therapeutic approaches, indicating that CIAPIN1 knock-down might serve as a combination with chemotherapeutical agents in leukemia diseases therapy.

Abstract
Apoptosis plays a key role in the physiology of multicellular organisms and is regulated by different promoting and inhibitory mechanisms. Cytokine-induced apoptotic inhibitor (CIAPI) was recently identified as a key factor involved in apoptosis inhibition in higher vertebrate lineages. However, most of the CIAPIs of lower vertebrate species are yet to be characterized. Herein, we molecularly characterized a teleostan counterpart of CIAPI from rock bream (Oplegnathus fasciatus), designating as RbCIAPI. The complete coding region of RbCIAPI was consisted of 942 nucleotides encoding a protein of 313 amino acids with a predicted molecular mass of ~33 kDa. RbCIAPI gene exhibited a multi-exonic architecture, consisting 9 exons interrupted by 8 introns. Protein sequence analysis revealed that RbCIAPI shares significant homology with known CIAPI counterparts, and phylogenetic reconstruction confirmed its closer evolutionary relationship with its fish counterparts. Ubiquitous spatial distribution of RbCIAPI was detected in our quantitative real time polymerase chain reaction (qPCR) analysis, where more prominent expression levels were observed in the blood and liver tissues. Moreover, the RbCIAPI basal transcription level was found to be modulated by different bacterial and viral stimuli, which could be plausibly supported by our previous observations on the transcriptional modulation of the caspase 3 counterpart of rock bream (Rbcasp3) in response to the same stimuli. In addition, our in vitro functional assay demonstrated that recombinant RbCIAPI could detectably inhibit the proteolysis activity of recombinant Rbcasp3. Collectively, our preliminary results suggest that RbCIAPI may play an anti-apoptotic role in rock bream physiology, likely by inhibiting the caspase-dependent apoptosis pathway. Therefore, RbCIAPI potentially plays an important role in host immunity by regulating the apoptosis process under pathogenic stress.

Abstract
Overexpression of cytokine-induced apoptosis inhibitor 1 (CIAPIN1) contributes to multidrug resistance (MDR) in breast cancer. This study aimed to evaluate the potential of CIAPIN1 gene silencing by RNA interference (RNAi) as a treatment for drug-resistant breast cancer and to investigate the effect of CIAPIN1 on the drug resistance of breast cancer in vivo. We used lentivirus-vector-based RNAi to knock down CIAPIN1 in nude mice bearing MDR breast cancer tumors and found that lentivirus-vector-mediated silencing of CIAPIN1 could efficiently and significantly inhibit tumor growth when combined with chemotherapy in vivo. Furthermore, Western blot analysis showed that both CIAPIN1 and P-glycoprotein expression were efficiently downregulated, and P53 was upregulated, after RNAi. Therefore, we concluded that lentivirus-vector-mediated RNAi targeting of CIAPIN1 is a potential approach to reverse MDR of breast cancer. In addition, CIAPIN1 may participate in MDR of breast cancer by regulating P-glycoprotein and P53 expression.

Abstract
Anamorsin (AM) is an antiapoptotic molecule that confers factor-independent survival on hematopoietic cells. AM-deficient (AM(-/-)) mice are embryonic lethal because of a defect in definitive hematopoiesis; however, the significance of AM in embryonic hematopoiesis remains unknown. This study characterized the hematopoietic defects in AM(-/-) fetal livers. The AM(-/-) fetal liver displayed significantly reduced numbers of c-Kit(+)Sca-1(+)Lin(-) (KSL) cells. An in vitro colony-forming unit assay showed that fetal liver cells isolated from AM(-/-) embryos gave rise to fewer colonies in all cell types. The reconstitution activity in AM(-/-) hematopoietic stem cells (HSCs) was markedly reduced in all lineages. Furthermore, the limiting dilution assay revealed that the number of fetal liver HSCs was reduced because of AM deficiency. Retrovirus-mediated AM expression rescued the defective hematopoietic colony-forming activities of AM(-/-) KSL cells. We also investigated the effects of AM deficiency on fetal liver stromal cells, which support hematopoiesis. Interestingly, primary stromal cell cultures from wild type fetal liver supported the growth of AM(-/-) KSL cells, but stromal cultures from AM(-/-) fetal liver provided little support of wild type KSL cell growth. These results demonstrated that AM was essential for both autonomous and extrinsic regulation of fetal liver hematopoiesis. This study provided new insight into the molecular regulation of hematopoiesis.

Abstract
CONTEXT Small cell lung cancers (SCLC) are heterogeneous and tumours differ in growth characteristics and treatment resistance. OBJECTIVE To get insight into the underlying protein profiles responsible for this heterogeneity, two subtypes of SCLC cells mutually differing in chemo resistance properties and growth characteristics are analysed. MATERIALS AND METHODS Two different electrophoresis approaches in combination with mass spectrometry were used to detect differences between the SCLC cell lines GLC1 and GLC1M13: IEF/SDS-PAGE as well as cetyltrimethylammonium bromide (CTAB)-SDS-PAGE. RESULTS Altogether 60 non redundant differentially expressed proteins were found of which 5 were verified by Western Blot analysis. DISCUSSION Most of these proteins identified are involved in processes of tumour progression. Therefore, these proteins are interesting candidates for further functional analysis. CONCLUSION Additional CTAB-SDS page is a complementary method to IEF-SDS page revealing a complete new subset of proteins differentially expressed between GLC1 and GLC1 M13 cells SCLC subtypes.

Abstract
Gastric cancer is one of the leading causes of malignancy-related mortality worldwide, and drug resistance hampered the clinical efficacy of chemotherapy. To better understand the molecular mechanism causing drug resistance, we previously established an isogenic pair of doxorubicin-sensitive and -resistant gastric cancer cell lines, SGC7901 and SGC7901/ADR cells. Here, we investigated how modulation of CUTL1 activity affects the response of gastric cancer to frequently used chemotherapeutic agents. In this study, we demonstrated that CUTL1 transcription activity was significantly reduced in doxorubicin-resistant cells. Furthermore, decreased CUTL1 expression was strongly associated with intrinsic drug resistance in human gastric cancer tissues and could be used as a poor prognosis biomarker. Both gain-of-function (by overexpression of active CUTL1) and loss-of-function (by CUTL1-specific shRNA knockdown) studies showed that increased CUTL1 activity significantly enhanced cell sensitivity to drugs and led to increased apoptosis, whereas decreased CUTL1 expression dramatically reduced cell sensitivity to drugs and thus fewer apoptoses. Importantly, modulation of CUTL1 activity resulted in altered sensitivity to multiple drugs. In vivo mouse studies indicated that overexpression of active CUTL1 significantly resulted in increased cancer tissue response to chemotherapy and therefore inhibited growth, whereas knockdown of CUTL1 conferred resistance to chemotherapy. Taken together, our results strongly indicate that CUTL1 activity is inversely associated with drug resistance and thus is an attractive therapeutic target to modulate multidrug resistance in gastric cancer.

Abstract
Gastric cancer is one of the leading causes of malignancy-related mortality in the world, and malignant growth is a crucial characteristic in gastric cancer. In our previous study, we found that growth arrest-specific gene 1 (GAS1) suppression was involved in making gastric cancer cells multidrug-resistant by protecting them from drug-induced apoptosis. In the present study, we investigated the potential role of GAS1 in the growth and proliferation of gastric cancer. We demonstrated that GAS1 expression was decreased in gastric cancer, and patients without GAS1 expression showed shorter survival times than those with GAS1 expression. Both gain-of-function (by overexpression of GAS1) and loss-of-function (by GAS1-specific small interfering RNA knockdown) studies showed that increased GAS1 expression significantly reduced the colony-forming ability of gastric cancer cells in vitro and reduced cell growth in vivo, whereas decreased GAS1 expression had the opposite effects. Moreover, upregulation of GAS1 induced cell apoptosis, and downregulation of GAS1 inhibited apoptosis. Furthermore, we demonstrated that GAS1 could induce gastric cancer cell apoptosis, at least in part through modulating the Bcl-2/Bax ratio and the activity of caspase-3. Taken together, our results strongly indicate that GAS1 expression was decreased in gastric cancer and was predictive of a poor prognosis. Restoration of GAS1 expression inhibited cell growth and promoted apoptosis of gastric cancer cells, at least in part through modulating the Bcl-2/Bax ratio and activating caspase-3, suggesting that GAS1 might be used as a novel therapeutic candidate for gastric cancer.

Abstract
Cytokine-induced apoptosis inhibitor 1 (CIAPIN1), initially named anamorsin, a newly indentified antiapoptotic molecule is a downstream effector of the receptor tyrosine kinase-Ras signaling pathway. Current study has revealed that CIAPIN1 may have wide and important functions, especially due to its close correlations with malignant tumors. However whether or not it is involved in the multi-drug resistance (MDR) process of breast cancer has not been elucidated. To explore the effect of CIAPIN1 on MDR, we examined the expression of P-gp and CIAPIN1 by immunohistochemistry and found there was positive correlation between them. Then we successfully interfered with RNA translation by the infection of siRNA of CIAPIN1 into MCF7/ADM breast cancer cell lines through a lentivirus, and the expression of the target gene was significantly inhibited. After RNAi the drug resistance was reduced significantly and the expression of MDR1mRNA and P-gp in MCF7/ADM cell lines showed a significant decrease. Also the expression of P53 protein increased in a statistically significant way (p ≤ 0.01) after RNAi exposure. In addition, flow cytometry analysis reveals that cell cycle and anti-apoptotic enhancing capability of cells changed after RNAi treatment. These results suggested CIAPIN1 may participate in breast cancer MDR by regulating MDR1 and P53 expression, changing cell cycle and enhancing the anti-apoptotic capability of cells.

Abstract
Background Epithelial ovarian cancer (EOC) is an aggressive disease with poor prognosis. The expression of cytokine-induced apoptosis inhibitor 1 (CIAPIN1) correlates with the malignant progression of several cancers. However, the relationship between the subcellular localization of CIAPIN1 and clinical characteristics in EOC remains unclear. Methods Immunohistochemistry was performed to detect CIAPIN1 expression in 108 EOC tissues. CIAPIN1 expressions in eight fresh EOC tissues were detected by Western blotting. The relationship between CIAPIN1 subcellular expression and patients’ clinicopathological features, including prognosis, was evaluated. Immunohistochemistry and immunofluorescence were employed to assess the CIAPIN1 subcellular localization in the EOC cell lines A2780 and HO8910. In addition, all patients were followed up to assess the prognostic value of CIAPIN1 in patients with EOC. Results CIAPIN1 is highly expressed in EOC, but is present at low levels in paired non-cancerous ovarian epithelial tissues. The results of Western blotting were in accordance with the immunohistochemical results. Poor differentiation of the tumors and EOC cell lines correlated with higher levels of CIAPIN1 nuclear expression. CIAPIN1 nuclear expression significantly correlated with the Federation International of Gynecology and Obstetrics (FIGO) stage and histological differentiation (P = 0.034 and P < 0.0001, respectively). Moreover, nuclear localization of CIAPIN1 was selected as an unfavorable prognostic factor by both univariate and multivariate analyses ( P < 0.001). However, no significant correlations were observed between cytoplasmic localization of CIAPIN1 and clinicopathological parameters. Conclusions CIAPIN1 might play a crucial role in the differentiation of EOC cells. Elevated expression of nuclear CIAPIN1 negatively correlated with the survival of EOC patients, suggesting that nuclear CIAPIN1 might serve as a prognostic biomarker for EOC patients.

Abstract
Cytokine-induced antiapoptotic molecule (CIAPIN1), a newly identified apoptosis inhibitor, has been found to participate in the process of proliferation and tumorigenicity for several cancers. The aim of this study was to evaluate the prognostic value of CIAPIN1 in pancreatic cancer and to probe its function in pancreatic carcinogenesis. We found that CIAPIN1 protein was absent or reduced in pancreatic cancer cell lines. There was also a loss or decrease in CIAPIN1 expression in 118 cases of pancreatic cancer tissues as compared with that in 82 cases of normal pancreatic tissues. In a Cox proportional hazards model, CIAPIN1 expression independently predicted better survival (P<0.0001). Adenoviral-mediated restoration of CIAPIN1 expression greatly repressed the proliferation of pancreatic cancer cell in vitro and suppressed the tumorigenicity of pancreatic cancer cell in Balb/c nude mice. Our data also revealed that inhibition of pancreatic cancer cells proliferation by enforcing CIAPIN1 expression at least partly through delaying cell cycle progression and inducing cell apoptosis. In summary, our work revealed a novel function of CIAPIN1, which might possibly be used as an independent prognostic factor and a potential therapeutic target for pancreatic cancer.

Abstract
Rho GDP dissociation inhibitor 2 (RhoGDI2) was initially identified as a regulator of the Rho family of GTPases. Our recent works suggest that RhoGDI2 promotes tumor growth and malignant progression, as well as enhances chemoresistance in gastric cancer. Here, we delineate the mechanism by which RhoGDI2 promotes gastric cancer cell invasion and chemoresistance using two-dimensional gel electrophoresis (2-DE) on proteins derived from a RhoGDI2-overexpressing SNU-484 human gastric cancer cell line and control cells. Differentially expressed proteins were identified using matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF-MS). In total, 47 differential protein spots were identified; 33 were upregulated, and 14 were downregulated by RhoGDI2 overexpression. Upregulation of SAE1, Cathepsin D, Cofilin1, CIAPIN1, and PAK2 proteins was validated by Western blot analysis. Loss-of-function analysis using small interference RNA (siRNA) directed against candidate genes reveals the need for CIAPIN1 and PAK2 in RhoGDI2-induced cancer cell invasion and Cathepsin D and PAK2 in RhoGDI2-mediated chemoresistance in gastric cancer cells. These data extend our understanding of the genes that act downstream of RhoGDI2 during the progression of gastric cancer and the acquisition of chemoresistance.

Abstract
Myogenesis is a well-characterized program of cellular differentiation that is exquisitely sensitive to the extracellular milieu. Systematic characterization of the myogenic secretome (i.e. the ensemble of secreted proteins) is, therefore, warranted for the identification of novel secretome components that regulate both the pluripotency of these progenitor mesenchymal cells, and also their commitment and passage through the differentiation program. Previously, we have successfully identified 26 secreted proteins in the mouse skeletal muscle cell line C2C12 (1). In an effort to attain a more comprehensive picture of the regulation of myogenesis by its extracellular milieu, quantitative profiling employing stable isotope labeling by amino acids in cell culture was implemented in conjunction with two parallel high throughput online reverse phase liquid chromatography-tandem mass spectrometry systems. In summary, 34 secreted proteins were quantified, 30 of which were shown to be differentially expressed during muscle development. Intriguingly, our analysis has revealed several novel up- and down-regulated secretome components that may have critical biological relevance for both the maintenance of pluripotency and the passage of cells through the differentiation program. In particular, the altered regulation of secretome components, including follistatin-like protein-1, osteoglycin, spondin-2, and cytokine-induced apoptosis inhibitor-1, along with constitutively expressed factors, such as fibulin-2, illustrate dynamic changes in the secretome that take place when differentiation to a specific lineage occurs.

Abstract
IMPORTANCE OF THE FIELD Cytokine-induced apoptosis inhibitor 1 (CIAPIN1) is a newly identified cytokine-induced apoptosis inhibitor, which has roles in cell division and angiogenesis. Owing to its prognostic value for human tumors and involvement in cancer progression and tumor cell resistance to anticancer agents, CIAPIN1 has been proposed as an attractive target for new anticancer interventions. AREAS COVERED IN THIS REVIEW We define CIAPIN1's potential function as a new therapeutic target for anticancer interventions and this review covers all related literature on CIAPIN1 in cancer from the past 5 years WHAT THE READER WILL GAIN Several preclinical studies have demonstrated that CIAPIN1 is associated with chemotherapy resistance, increased tumor recurrence and shorter patient survival in different human tumor models, making anti-CIAPIN1 therapy an attractive cancer treatment strategy. Recent studies also suggest that CIAPIN1 is expressed at low levels in some types of malignant tumors and that its overexpression may inhibit their proliferation or tumorigenesis. TAKE HOME MESSAGE Considering that the exact expression and function of CIAPIN1 are still not well characterized and understood, better knowledge of CIAPIN1 in normal versus tumor tissues will be instrumental for the design of optimal strategies to selectively disrupt CIAPIN1 in cancer.

Abstract
Supercritical fluid extraction (SFE) was used to extract saikosaponins a, c and d from the root of Bupleurum falcatum. An orthogonal array design L(9)(3)(4) was employed as a chemometric method for the optimization of the SFE conditions. The effects of four factors including pressure (30-40 MPa), temperature (40-50 degrees C), ethanol concentration (60-100%) and time (2.5-3.5 h) on the yields of saikosaponins were investigated by a preparative SFE system in the SFE mode. Under the optimized conditions, namely 35 MPa of pressure, 45 degrees C of temperature, 80% of ethanol concentration and 3.0 h of time, the yields of saikosaponin c, saikosaponin a, saikosaponin d, total saikosaponins and SFE extract were 0.16, 0.12, 0.96, 1.24 and 16.48 mg/g, respectively. Determinations of the saikosaponins were performed by HPLC.

Abstract
AIM: To investigate the relationship between the reversing effect of phenylpropanoid glycoside (PPG) on multidrug resistance of colon carcinoma LoVo/Adr cells and apoptosis.
METHODS: LoVo/Adr cells were divided into three groups: non-treatment (negative control) group, PPG treatment group (treated with 40 mg/L PPG) and verapamil treatment (positive control) group (treated with 5 mg/L VP). The effects of PPG on multidrug resistance of LoVo/Adr cells were examined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay. The effects of PPG on cell apoptosis were detected by flow cytometry. The effects of PPG on the activity of Caspase-3 were evaluated by determining pNA release rate.
RESULTS: PPG could decrease the half maximal inhibitory concentration (IC50) of adriamycin in LoVo cells and reverse their resistance to adriamycin. The reversal index was 9.93. PPG could significantly induce the apoptosis of LoVo cells when compared with the non-treatment group (P < 0.01). The rate of pNA release in the PPG treatment group was significantly higher than that in the non-treatment group (31.75 ± 4.34 pmol/min vs 18.45 ± 2.39 pmol/min, P < 0.01). Caspase-3 inhibitor Z-VAD-FMK could significantly inhibit PPG-induced pNA release (17.69 ± 2.68 pmol/min vs 31.75 ± 4.34 pmol/min, P < 0.01).
CONCLUSION: PPG reverse multidrug resistance of LoVo/Adr cells perhaps through induction of Caspase 3-dependent apoptosis.
