4. Expression of histidine triad nucleotide-binding protein 1 in clear cell renal cell carcinoma and its clinical significance
Tumor 2011;31(5):436-441
Objective: To determine the expressions of histidine triad nucleotide-binding protein 1 (HINT1) mRNA and protein in clear cell renal cell carcinoma (ccRCC) and their relationships with clinicopatholgical features. Methods: Real-time fluorescence quantitative reverse transcription PCR (RFQ-RT-PCR) was used to detect the expressions of HINT1 mRNA in 36 cases of fresh ccRCC and 37 cases of normal kidney tissues (29 paired cases), as well as their relationships with clinicopathological features were analyzed. Immunohistochemistry was used to detect the distribution and expression of HINT1 protein in 30 cases of paraffin embedded fresh ccRCC tissues and 12 cases of paraffin-embedded adjacent normal kidney tissues, as well as their relationships with clinicopathological features were analyzed. Results: The expression levels of HINT1 mRNA in 29 cases of paired ccRCC and normal kidney tissues were 0.209±0.033 and 0.733±0.136, respectively (P<0.001). The expression levels of HINT1 mRNA in 36 cases of ccRCC and 37 cases of normal kidney tissues were 0.245±0.035 and 0.694± 0.108, respectively (P<0.001). The positive expression rate of HINT1 protein in the adjacent normal kidney tissues was 100% (12/12), diffusely distributing in the nucleus and cytoplasm. HINT1 protein immunostaining in proximal convoluted tubule was stronger than that in distal convoluted tubule, while it was partially weaker in glomerular basement membrane and Bowman's capsule. The HINT1 protein expression was negative in renal interstitium. HINT1 protein expression distributing in nucleus and cytoplasm was 60% (18/30) positive in ccRCC, while it was negative in intercellular substance (P<0.01). The tendency of HINT1 mRNA expression in ccRCC and normal kidney tissues and their relationships with the clinicopathological features were the same as those of HINT1 protein. The expressions of HINT1 mRNA and protein in stages T1-2 of ccRCC were higher than those in stages T3-4 (P<0.05), and the same result was found in normal kidney tissues and ccRCC tissues. The expressions of HINT1 mRNA and protein were not correlated with Fuhrman grade, gender, age and tumor size (P>0.05). Conclusion: HINT1 may play a role as tumor suppressor gene in ccRCC. The abnormal expression of HINT1 may be associated with the abnormal regulation before translation. Abnormal expressions of HINT1 mRNA and protein may serve as a marker for the prognosis of ccRCC patients.

Results:Before treatment, there were no significant differences in serum levels of H-FABP, cTnI, and NT-proBNP as well as LVEF and APACHE II score between the control and study groups (all P > 0.05). At 6 hours after treatment, serum levels of H-FABP, cTnI, and NT-proBNP in the control and study groups [(26.22 ± 7.22) μg/L vs. (39.93 ± 9.85) μg/L, (25.97 ± 6.93) μg/L vs. (34.86 ± 8.55) μg/L, (0.004 ± 0.002) μg/L vs. (1.580 ± 0.360) μg/L, (0.003 ± 0.003) μg/L vs. (0.760 ± 0.210) μg/L, (1 561.73 ± 633.70) ng/L vs. (2 570.06 ± 747.95) ng/L, (1 602.28 ± 681.45) ng/L vs. (2 225.53 ± 585.14) ng/L] were significantly increased compared with before treatment ( t = 7.188, 5.172, 28.031, 23.079, 6.586, 4.443, all P < 0.05). After treatment, serum levels of H-FABP, cTnI, and NT-proBNP in the study group were significantly lower than those in the control group ( t = 2.489, 12.598, 2.323, all P < 0.05). In each group, serum level of H-FABP at 72 hours after treatment was significantly lower than that at 6 hours after treatment [(39.93 ± 9.85) μg/L vs. (6.28 ± 1.07) μg/L, (34.86 ± 8.55) μg/L vs. (5.82 ± 1.88) μg/L], serum levels of cTnI and NT-proBNP at 72 hours after treatment were significantly increased compared with those at 6 hours after treatment [(1.58 ± 0.36) μg/L vs. (2.72 ± 0.55) μg/L, (0.76 ± 0.21) μg/L vs. (1.78 ± 0.49) μg/L, (2 570.06 ± 747.95 ) ng/L vs. (3 623.27 ± 1 105.28) ng/L, (2 225.53 ± 585.14) ng/L vs. (3 128.08 ± 1 098.07) ng/L, t = 11.105, 12.251, 5.053, 4.645, all P < 0.05). At 72 hours after treatment, serum levels of cTnI and NT-proBNP levels in the control group were significantly higher than those in the study group ( t = 8.171, 2.035, both P < 0.05). At 72 hours after treatment, there was no significant difference in serum H-FABP level between the control and study groups ( P > 0.05). At 72 hours after treatment, APACHE II score in each group was significantly decreased and LVEF in each group was significantly increased compared with before treatment ( t = 7.718, 11.380, 9.049, 9.501, all P < 0.05). The change in APACHE II score at 72 hours after treatment relative to before treatment in the study group was more obvious than that in the control group ( t = 2.583, P < 0.05). At 72 hours after treatment, there were no significant differences in LVEF, ICU stay and 28-day mortality between the control and study groups (all P > 0.05). Conclusion:Levosimendan can reduce the serum levels of H-FABP, cTnI and NT-proBNP as well as APACHE II score in patients with sepsis, increase serum level of LVEF, and alleviate myocardial injury.
