AIM: To evaluate the expression of iNOS mRNA in different invasion ability colon carcinoma cell strains. METHODS: MTT was used to detect the growth and reproduction of colon cancer cell strain CW-2 and LS174T. RT-PCR and Northern blot were used to detect expression of iNOS mRNA in colon cancer. RESULTS: MTT growth curve displayed that colon cancer cell strain LS174T grew and reproduced faster than cell strain CW-2. RT-PCR showed that iNOS mRNA expressed strongly in CW-2 cell strain, while iNOS mRNA expressed weakly in LS174T cell strain. Northern blot detected that iNOS mRNA expressed obviously in CW-2 cell strain, but cell strain LS174T have no obvious iNOS mRNA expression. All-trans retinoic acid (ATRA) had no obvious effect on iNOS mRNA expression in CW-2 cell strain of colon cancer. CONCLUSIONS: ATRA has no obvious effect on iNOS mRNA expression. iNOS has a dual effect on tumor growth. In low-metastatic colon carcinoma CW-2, iNOS may exert a anti-tumor influence by cytotoxicity or inducing cell apoptosis. In high-metastatic colon cancer LS174T, iNOS produced low concentration of NO, which may be an important signal-transduction molecule for increasing blood supply and angiogenesis, which improve the growth, invasion and metastasis of tumor.

Abstract: Objective To investigate the expression level and clinical significance of serum liver fibrosis-associated lncRNA1 (lnc-LFAR1) in patients with chronic hepatitis B cirrhosis, aiming to analyze its correlation with interleukin-6 (IL-6), interleukin-1β (IL-1β), and liver function. Methods Patients with chronic hepatitis B (CHB) cirrhosis and CHB diagnosed and treated in Dongguan City People's Hospital from March 2016 to December 2019 were selected and divided into the liver cirrhosis group (n=80) and the CHB group (n=80), and 80 healthy people with physical examination during the same period were selected as healthy group. The serum levels of lnc-LFAR1, interleukin-6 (IL-6), albumin (ALB), interleukin-1β (IL-1β) and liver function indicators, including albumin (ALB) and alanine aminotransferase (ALT) were measured and analyzed. The correlation between serum lnc-LFAR1 expression level and IL-6, IL-1β was assessed, and the levels of lnc-LFAR1, IL-6, IL-1β, ALB and ALT were compared among patients with CHB cirrhosis of different Child-Pugh grades. Results The serum levels of lnc-LFAR1, IL-6, IL-1β and ALT in the patients with liver cirrhosis [(1.85± 0.62), (41.76±13.92) ng/mL, (7.78±1.95) pg/mL, (148.37±29.67) U/L] were higher than those in the CHB group [(1.42±0.47), (23.56± 7.85) ng/mL, (5.42±1.41) pg/mL, (87.59±17.52) U/L] and the healthy group [(1.01±0.34), (6.70±2.23) ng/mL, (3.13± 0.78) pg/mL, (15.44±3.10) U/L] (P<0.05), while the ALB levels (30.54±3.82) g/L were lower than those in the CHB group (37.27±4.34) g/L and the healthy group (45.26±5.66) g/L (P<0.05). Serum lnc-LFAR1, IL-6, IL-1β and ALT levels in the CHB group were higher than those in the healthy group (P<0.05), and ALB levels were lower than those in the healthy group (P<0.05); the serum levels of lnc-LFAR1, IL-6, IL-1β in patients with CHB cirrhosis were negatively correlated with ALB (P<0.05), and positively correlated with ALT (P<0.05); the serum expression level of lnc-LFAR1 in patients with CHB cirrhosis was positively correlated with IL-6 and IL-1β (r=0.598, 0.571, P<0.05); with the increase of Child-Pugh grade, the serum levels of lnc-LFAR1, IL-6, IL-1β, and ALT in patients with CHB cirrhosis gradually increased (P<0.05), and the level of ALB gradually decreased (P<0.05). Conclusions Serum lnc-LFAR1 expression level is higher in patients with CHB cirrhosis, which is obviously related to IL-6, IL-1β, ALB and ALT. Therefore, the evaluation of serum lnc-LFAR1 expression level is helpful in the clinical assessment of the condition of CHB cirrhosis patients.

Objective:To study the molecular mechanism for momordin in inducing apoptosis of multidrug-resistant human chronic leukemia K562/A02 cells. Methods:The growth inhibition value of K562/A02 cells was detected by CCK-8 method. Cell apoptosis was analyzed by Annexin Ⅴ flow cytometry (FCM) and cell morphological examination. FCM was also used in determining expression of P-glycoprotein, p53 protein, bcl-2 protein and caspase activity. Results:Momordin inhibited the proliferation of K562/A02 cells in a dose-dependent manner. It also induced cell apoptosis, reduced the expression of P-glycoprotein, p53 protein and bcl-2 protein, and increased caspase-3 and caspase-8 activity.Conclusion:Momordin reversed the inhibition of apoptosis in multidrug-resistant K562/A02 cells. The molecular mechanism may be related with down-regulation of expression of p53 protein, P-glycoprotein, and bcl-2 protein and up-regulation of caspase-3 and caspase-8 activities.

AIM: To explore the change of the expression of cell adhesion molecule CD_ 54 and CD_ 44 in erythroleukemic K562 apoptosis cells induced by momordin from momordica charantia seeds and study the effects of cell adhesion molecule CD_ 54 and CD_ 44 on cell apoptosis induced by momordin. METHODS: After the treatment of K562 cells with appropriated concentration momordin, CCK-8 test was employed to determine K562 cells growth; flow cytometry FACScan (FITC-Annexin V staining) and electron microscopy were used to detect apoptosis; The expression of CD_ 54 and CD_ 44 were examined by flow cytometry FACScan (FITC-CD_ 54 and PE-CD_ 44 staining). RESULTS: CCK-8 test showed K562 cells growth was significant inhibited by momordin; the apoptosis was detected by cell morphology and flow cytometry FACScan (FITC-Annexin V) in K562 cells after treatment by appropriated concentration momordin. The expressions of CD_ 54 and CD_ 44 in momordin treated K562 cells were 18.62 % and 1.32 % respectively, and in negative momordin treated K562 cells were 0.25 % and 0.17 % respectively, and momordin could up-expresses the protein of CD_ 54 18.37 % and CD_ 44 1.15 %. CONCLUSION: Momordin can markedly induce the K562 cell to apoptosis. The up-expressions of CD_ 54 exist in the process of apoptosis induced by momordin. The change of cell adhesion molecule maybe one of the key factors in the mechanisms of apoptosis induced by momordin, and its mechanism maybe involve in adhesion-dependent apoptosis.
