ABSTRACT
Objective To explore whether CD44 +/CD24 + expressing cervical cancer cells are resistant to X-ray irradiation and investigate the underlying mechanism.Methods Cervical cancer cell line (Siha) was cultured in vitro and the CD44 +/CD24 + expressing cells were sorted with a flow cytometer.The cells were irradiated with 8,16 and 30 Gy of 6 MV X-rays.Colony formation test was used to evaluate the radiosensitivity of CD44 +/CD24 + expressing cervical cancer cells.Cell morphology was observed by electronmicroscopy,cell apoptosis was analyzed with a flow cytometer and also verified with a DNA ladder assay.Gene expression was determined by RT-PCR.Results After radiation,the ratio of CD44 +/CD24 + cells significantly increased.Compared to Siha cells,the radiosensitivity of CD44 +/ CD24 + cells decreased (t =93.99-400.45,P ＜0.05),and the expressions of bcl-2,survivin and Oct4 mRNA increased in CD44 +/CD24 + cells (t =221.35,941.65,82.27,P ＜0.01).Both apoptotic body and specific DNA ladder pattern were observed in cells but not in the CD44 +/CD24 + Sihacells which had no obvious morphological changes of apoptosis.Conclusions The CD44 +/CD24 + expressing cervical cancer cells are resistant to X-rays due to expression of anti-apoptosis factors.
ABSTRACT
Background and purpose:One of the reasons why cancer cells are resistant to chemotherapy is the existence of cancer stem cells. The purpose of this study was to investigate the chemoresistance of CD44+/CD24+ Siha cells to cisplatin and its mechanisms.Methods:Siha cells were cultivatedin vitro. The CD44+/CD24+ Siha cells were sorted out by fluorescence activated cell sorter (FACS) andin vitro proliferation was detected by MTT assay after treatment with the different concentrations of cisplatin. The cell apoptosis rate was detected by flow cytometry after 10 μg/mL cisplatin acted on CD44+/CD24+ Siha cells for 24, 48 and 72 h. The relative mRNA and protein expressions of Bcl-2, Oct-4 and ABCG2 were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot, respectively. Results:The survival rates of CD44+/CD24+ Siha cells treated with different concentrations of cisplatin (0.1, 1, 5, 10, 15 and 20 μg/mL) were higher than those of their parental Siha cells [(88.42±1.51)%vs (92.87±1.5)%, (79.94±1.05)%vs (84.72±1.09)%, (69.78±0.81)%vs (75.13±2.86)%, (58.97±0.70)%vs (65.79±2.71)%, (49.60±0.88)%vs (52.10±0.52)%, (45.13±0.69)%vs (48.84±1.02)%,P<0.05]. Compared with their parental Siha cells, the apoptosis rates of CD44+/CD24+ Siha cells were lower after 10 μg/mL of cisplatin acting on them for 24, 48 and 72 h, respectively [(3.05±0.16)%vs (5.17±0.27)%, (17.94±2.02)%vs (32.60±4.28)% and (40.14±3.01)%vs (56.62±5.32)%,P<0.05]. The results from both qRT-PCR and Western blot indicated that Oct-4, ABCG2 and Bcl-2 were highly expressed on CD44+/CD24+ Siha cells. A significant difference was found in Oct-4, ABCG2 and Bcl-2 expression between CD44+/CD24+Siha cells and their parental cells (P=0.015<0.05).Conclusion:CD44+/CD24+ Siha cells could be resistant to apoptosis induced by cisplatin and expressed high levels of cancer stem cell markers such as Oct-4 and ABCG2. This study lays the basis for useful isolation and further targeted therapy of cervical cancer stem cells.
ABSTRACT
Objective To investigate the correlation of XRCC1 Arg194Trp Arg399Gln Single nucleotide polymor-phism (SNP) with radiotherapy response of squamous cell carcinoma of cervix. Methods Patients with exogenous type cer-vical squamous cell carcinoma confirmed by histopathology were selected for our study. These include:patients in stageⅠ(4 cases), patients in stageⅡ(36 cases), patients in stageⅢ(30 cases), patients in stageⅣ (3 cases). There are 30 patients with tumor diameter less than 4 cm and 43 patients with tumor diameter over 4 cm in our test. There are 36 cases with dose point A less than 80 Gy and 37 cases with dose point A over 80 Gy . Radiotherapy outcomes showed 47 cases of complete re-mission and 26 cases of part remission. Polymorphisms Arg194Trp, Arg399Gln of XRCC1 gene in 73 cervical cancer pa-tients were analyzed by mismatch amplification polymerase chain reaction (MAMA-PCR). Results Arg/Arg, Arg/Trp, TrP/Trp of Arg194Trp genotype distribution were 31 (42.5%), 37 (50.7%), 5 (6.8%) respectively. Arg/Arg, Arg/Gln, Gln/Gln of Arg399Gln distribution were 6 (35.6%), 39 (53.4%), 8 (11.0%) respectively. The response to radiotherapy was not statistical-ly significant in three genotypes, Arg/Arg, Arg/Trp, TrP/Trp of XRCC1 at codon 194(P>0.05). Neither was XRCC1 at codon 399. Multivariate analysis showed that late clinical stage was a risk factor of part remission. Conclusion SNP of XRCC1 gene at codon 194 and codon 399 could not predict clinical response of patients with squamous cell carcinoma of cervix to ra-diotherapy. The patients with advanced cervical cancer had poor response to radiotherapy.

Changes of MCP-1, NF-κB, TGF-β1 and UAER were observed before and after the treatment . The results showed that MCP-1 , NF-κB and TGF-β1 had significant positive correlation with UAER ( P ment , the levels of MCP-1 , NF-κB , TGF-β1 and UAER in the control group and treatment group after treat-ment were significantly declined ( P < 0 . 05 ) . Compared with the control group , after treatment , the levels of MCP-1 , NF-κB , TGF-β1 and UAER of the treatment group were obviously reduced ( P < 0 . 05 , or P <0 . 01 ) . It was concluded that DJC can reduce the UAER , delay the renal injury , and downregulate levels of MCP-1, NF-κB and TGF-β1, block the expression of inflammatory mediators, inhibit inflammatory reaction and improve microinflammatory state of EDN. This may be one of the important mechanisms in the protection of renal function .
ABSTRACT
This study was aimed to observe the effect of Danzhi Jiangtang Capsule ( DJC ) on expression of solu-ble thrombomodulin ( sTM ) and soluble endothelial cell protein C receptor ( sEPCR ) in experimental rats of type 2 diabetes mellitus (T2DM). This study also explored possible mechanisms of Yiqi Yangyin Huoxue method on vascular endothelial tissue and discussed mechanisms of prevention and management of T2DM vascular lesions . A total of 60 male Sprague-Dawley ( SD ) rats were fed for one week and then randomly divided into the nor-mal control group ( group N , n = 12 , rats were fed with routine food ) and diabetes mellitus group ( n = 48 , rats were fed with high-fat diet). After 4 weeks, rats in the diabetes mellitus group were injected with strepto-zotocin ( STZ ) to induce T2DM . According to the blood glucose level , rats were divided into three groups , wh ich were the model group (group M), pioglitazone (group P), and pioglitazone combined with DJC (group D). Group P was treated with pioglitazone (10 mg?kg-1?d-1), group D was given pioglitazone (10 mg?kg-1?d-1) and DJC ( 0 . 47 g?kg-1?d-1 ) . The group N and group M were treated with sodium chloride ( 5 mL?kg -1?d-1 ) . After four-week drug administration , the levels of sTM , sEPCR , PT , APTT and FIB in each group were tested . The results showed that compared with the control group , the levels of sTM , sEPCR and FIB in group M , group P and group D were significantly increased ( P < 0 . 05 ) , and the levels of PT and APTT were obviously reduced ( P < 0 . 05 ) . Compared with group P , the levels of sTM , sEPCR , FIB of group D were significantly reduced ( P< 0 . 01 ) , and the level of APTT was significantly increased ( P < 0 . 05 ) . However , there was no significant dif-ference in the increasing of PT. It was concluded that the Yiqi Yangyin Huoxue method can reduce the levels of sTM and sEPCR , and effectively improve coagulation . The possible mechanisms of protective effect on the vascular endothelium can be from reducing levels of sTM and sEPCR in order to enhance the activity of anti-coagulation and fibrinolysis , regulate the function of blood coagulation to improve hypercoagulable state .
ABSTRACT
Objective To evaluate the relationship between glycemic control and lipid profile in patients with type 2 diabetes.Methods The patients with type 2 diabetes taking oral antidiabetic agents only were investigated for their levels of blood glucose and lipid profile.With a standard for valid blood glucose control( HbA1c ＜7％ ),the patients were divided into two groups,reached the goal group and not reached the goal group,and the lipid profile was compared between the two groups.Results Completed study had been obtained 173 patients,average HbAlc,7.9％,total success rate of glycemic control,with 43.4％ being the figure reported.We can see a lower triglyceride( TG),total cholesterol (TC) and low density lipoprotein cholesterol(LDL-C) level and a higher high density lipoprotein cholesterol (HDL-C) level in the group reaching the stantard ( t =- 2.437,- 2.067,2.005,- 2.984,P =0.016,0.040,0.047,0.003).Conclusion The blood lipid profile should be considered while the level of glucose of patients with type 2 diabetes taking oral antidiabetic agents alone are controlled.
