多发性骨髓瘤(MM)作为中老年常见的血液肿瘤之一,预后相对较差,常规化学疗法(化疗)疗效欠理想。硼替佐米作为一种新药,属于蛋白酶体抑制剂,通过全新的机制达到抗骨髓瘤的作用。国内外临床研究表明硼替佐米单药以及同常规化疗药物组成的联合化疗方案对初始治疗,以及复发难治的MM患者均有良好疗效。因此以硼替佐米为主的联合化疗方案已被美国国家综合癌症协作网推荐作为MM患者治疗的重要选择之一。现将硼替佐米在MM治疗上的进展作一综述。 相似文献

Objectives
To investigate the genetic variability of multiple drug resistant 1 (MDR1) gene C3435T polymorphism in four Southern Chinese populations.Methods
Using discrimination real-time PCR, we determined the MDR1 C3435T polymorphism in three ethnic minority groups Lahu (n = 104), Wa (n = 101) and Bulang (n = 100) in Yunnan Province, and Han Chinese (n = 199) in Hong Kong. All of them were residents in Southern China.Results
For 3435 CC genotype, the frequency in Han Chinese in Hong Kong (44.7%) is significantly higher than in Lahu (16.3%) and Wa (29.7%) minorities, P < 0.05. For 3435 CT genotype, the frequency in Han Chinese in Hong Kong (44.2%) is lower than in Lahu (58.7%), P < 0.05. For 3435 TT genotype, frequency in Han Chinese in Hong Kong (11.1%) is lower than in Lahu (25%) and Wa (20.8%), P < 0.05. For 3435 C allele, frequency in Han Chinese in Hong Kong (66.8%) is higher than in Lahu (45.7%) and Wa (54.5%), P < 0.01. For 3435T allele, frequency in Han Chinese in Hong Kong (33.2%) is lower than in Lahu (54.3%) and Wa (45.5%), P < 0.01. For MDR1 3435T allele, the frequencies are significantly higher in our four Southern Chinese populations than in African population (P < 0.001) and significantly lower than in South-west Asians (P < 0.05); Han Chinese in Hong Kong displayed significant difference from all the other ethnic populations except Japanese (P < 0.05); compared with Caucasian and other ethnic Asians, Lahu minority showed no frequency difference (P > 0.05) between Caucasian and other Asians (except Japanese).Conclusions
This is the first study to show the C3435T polymorphism of MDR1 in Southern Chinese populations. The frequency of C3435T, an important determinant for multidrug resistance, displays significant difference in ethnics. It may help for individualizing therapy for cancer, HIV and other common diseases. 相似文献12.

C1236T, G2677T/A, and C3435T polymorphism of the multidrug resistance (MDR1) gene have substantial impact on expression or activity of P‐glycoprotein (P‐gp). We developed new methods based on amplification refractory mutation system (ARMS) to detect these polymorphisms. Tetra‐primers amplification in a single tube was established to detect C1236T and C3435T polymorphism. For G2677T/A polymorphism, a two‐step allele‐specific amplification method was used. MDR1 genotypes of 177 Chinese subjects were determined by the methods we established. The methods we established were verified with gene sequencing. Gene frequencies of 1236C and 1236T were 37.8 and 62.2%, respectively; gene frequencies of 2677G, 2677T and 2677A were 44.1, 38.4 and 17.5%, respectively; the gene frequencies of 3435C and 3435T were 65.0 and 35.0%, respectively. The results were similar with other studies on Oriental subjects. The methods we established are simple, accurate, and economical, and can provide reliable approaches for determining MDR1 polymorphism. J. Clin. Lab.

We investigated whether the MDR1 (multidrug resistance 1) gene single nucleotide polymorphism (SNP) and haplotype variants were associated with the susceptibility to diffuse large B-cell lymphoma (DLBCL). A total of 129 DLBCL patients and 208 healthy controls from Jiangsu Han population were enrolled in this study. They were genotyped by polymerase chain reaction-allele specific primers (PCR-ASP) method or DNA direct sequencing at three common loci: C1236T, G2677T/A and C3435T. At locus G2677T/A, allele G and genotype GT were significantly more common in DLBCL (G: OR = 1.48, 95% CI: 1.08–2.02, Pc = 0.03; GT: OR = 1.96, 95% CI: 1.25–3.07, Pc < 0.01), while genotype AT in this locus seemed to be protective (OR = 0.29, 95% CI: 0.02–0.72, Pc = 0.03). TT genotype at locus C3435T showed a risk factor in DLBCL (OR = 2.38, 95% CI: 1.52–3.74, Pc < 0.01). The frequency of T-G-T haplotype was significantly increased in DLBCL group (OR = 5.21, 95% CI: 2.58–10.54, Pc < 0.01); haplotype of G-T in 2677–3435 and diplotype of 2677GT/3435TT were significantly more frequent in DLBCL group (G-T: OR = 3.97, 95% CI: 2.31–6.85, Pc < 0.01; 2677GT/3435TT: OR = 4.55, 95% CI: 2.02–10.22, Pc < 0.01). Our findings demonstrate that G, GT at locus G2677T/A, and TT at locus C3435T might contribute to the susceptibility to DLBCL, as well as haplotype of T-G-T, G-T in 2677–3435 and diplotype of 2677GT/3435TT, while AT at locus G2677T/A might be a protective genotype. These findings could provide evidence that the MDR1 SNPs may modify the susceptibility to DLBCL and shade new lights in disease association studies. 相似文献

The single nucleotide polymorphism and haplotype analysis of MDR1 in Jiangsu Han population of China
The aim of this study was to perform the frequency distribution of MDR1 gene SNPs and haplotypes of Jiangsu Han population in China. A total of 225 Jiangsu Han unrelated volunteers were enrolled and genotyped by PCR-ASP method at three loci: C1236 T (rs1128503), G2677 T/A (rs2032582) and C3435 T (rs1045642). In total, C and T were found at locus 1236, with the frequency of 35% and 65%, respectively. The most frequent allele at locus 2677 was G with the frequency of 44%, followed by T (41%) and A (15%). At locus 3435, C was more common (60%) than T (40%). The most common haplotype at loci 1236-2677-3435 was T-T-T (31.84%), at loci 1236-2677 was T-T (37.68%), at loci 2677-3435 was G-C (39.06%), and at loci 1236-3435 was T-T (34.28%). The haplotype linkage disequilibrium study found that all three loci were in linkage disequilibrium, such as T-T at loci 1236-2677, T-T at loci 2677-3435 and C-C at loci 1236-3435 (P < 0.01). The dendrogram study indicated that the distribution of MDR1 SNPs in Jiangsu Han population were close to Japan and Malay populations and far away from European countries. These findings could shade new lights in population genetics and anthropology studies of Han-Chinese. It also provides basic data for research on MDR1 gene polymorphism, disease association and drug resistance study. 相似文献

Rapid detection of the UGT1A1 single nucleotide polymorphism G211A using real-time PCR with Taqman minor groove binder probes 总被引:1,自引:0,他引:1
Wong FL Wang MK Boo NY Hamidah NH Ainoon BO 《Journal of clinical laboratory analysis》2007,21(3):167-172
The UGT1A1 Taqman MGB probe single nucleotide polymorphism (SNP) genotyping assay was developed to detect nucleotide 211 of the UDP-glucoronocyltransferase 1A1 (UGT1A1) gene. Defects in this enzyme interfere with process of conjugation of bilirubin and cause unconjugated hyperbilirubinemia. Variation at nucleotide 211 in the coding region of the UGT1A1 gene has been shown to be prevalent in Japanese and Chinese. Using an ABI sequence detection system (SDS) 7000, an allele-specific real-time PCR-based genotyping method was established to detect nucleotide G211A. Cord blood from 125 infants without hyperbilirubinemia (controls) were compared with cord blood from 74 infants (cases) with severe hyperbilirubinemia (total serum bilirubin > 300 micromol/L). Homozygous variation of the UGT1A1 gene at nucleotide 211(A/A) is significantly more common in cases (14.9%) than in controls (0.8%) (P<0.001). Direct sequencing from 20 randomly selected samples showed eight samples with homozygous wild type, seven with homozygous variant, and five samples were heterozygous. The result from this assay was in complete concordance with the DNA sequencing result and clearly discriminate wild-type (G/G), homozygous variant (A/A), and heterozygous (G/A). This assay is rapid and robust for screening of SNP G211A to determine if this polymorphism plays a role in causing severe neonatal jaundice in the local context. 相似文献
