Abstract
Anaplastic thyroid cancer (ATC) is an aggressive type of thyroid cancer with a high mortality rate. Cytotoxic drugs are among the treatment modalities usually used for ATC treatment. However, systemic chemotherapies for ATC have not been shown to have remarkable efficacy. ATP-binding cassette (ABC) transporters have been suggested as a possible mechanism in ATC resistance to chemotherapy. This systematic review was aimed to define the possible roles of ABC transporters in ATC resistance to chemotherapy. Numerous databases, including Scopus, Web of Science, PubMed, Cochrane Library, Ovid, ProQuest, and EBSCO, were searched for papers published since 1990, with predefined keywords. The literature searches were updated twice, in 2015 and 2017. All identified articles were reviewed, and 14 papers that met the inclusion criteria were selected. In the eligible studies, the roles of 10 out of 49 ABC transporters were evaluated; among them, three pumps (ABCB1, ABCC1, and ABCG2) were the most studied transporters in ATC samples. ABCC1 and ABCG2 had the highest expression rates in ATC, and ABCB1 ranked second among the inspected transporters. In conclusion, ABC transporters are the major determinants of ATC resistance to chemotherapy. By identifying these transporters, we can tailor the best treatment approach for patients with ATC. Additional studies are needed to define the exact role of each ABC transporter and other mechanisms in ATC drug resistance.

Abstract
While most thyroid cancers are slow-growing and have an excellent prognosis after appropriate treatment, a subset of thyroid cancers behave aggressively, and approximately 1500 individuals in the US will die of the disease in the year 2007. Advanced thyroid malignancies can cause distressing and life-threatening symptoms by local invasion in the neck, growth of distant metastases in the lung, bone, and other organs, and tumor production of bioactive substances in the case of medullary thyroid cancer. This article will review palliative modalities, including surgery, radioactive iodine, external beam radiation, and chemotherapy, as well as novel targeted therapies, for the treatment of patients with advanced thyroid malignancies.

Abstract
Recent studies have demonstrated that Y-box binding protein (YB-1) regulates the transcription of genes linked to carcinoma progression. In this study, we investigated the expression of this protein in thyroid neoplasms to elucidate its significance. The expression of YB-1 was immunohistochemically investigated using the monoclonal antibody for various thyroid neoplasms. Normal follicles did not overexpress YB-1, and only moderate overexpression of YB-1 was observed in some follicular tumors and papillary carcinoma, especially those of a larger size. In contrast, 92.9% of anaplastic carcinoma strongly overexpressed YB-1. YB-1 immunoreactivity was seen in both cytoplasms and cell nuclei, but the former was more predominant. These findings suggest that YB-1 plays a role in regulating the transcription as well as translation of genes contributing to the anaplastic transformation of thyroid carcinoma.

Abstract
Multidrug resistance-associated protein (MRP) is one of the major factors responsible for non-P-glycoprotein (Pgp)-mediated multidrug resistance of human tumour cells. In this study, we examined MRP and aberrant p53 expression in 54 colorectal cancers (CRC), 35 carcinoma in adenomas (CIA) and 40 adenomatous polyps by immunohistochemical procedures. 38 of 54 (70%) CRCs, 16 of 35 (46%) CIAs and 3 of 40 (8%) adenomatous polyps were MRP positive (chi 2 test, P < 0.0001). 36/54 (67%) CRCs, 10/35 (29%) CIAs and 0/40 adenomatous polyps were p53 positive. 30 of the 36 p53-positive CRCs were also MRP positive and 8/10 CIAs were both p53 and MRP positive. MRP overexpression correlated with aberrant p53 accumulation in CRCs and CIAs (chi 2 test, P < = or 0.01). Coexpression of MRP and p53 in the same cells was confirmed in the CRCs and CIAs by double staining procedures. These results suggested that MRP overexpression is related to aberrant p53 expression in CRC.

Abstract
Two different ATP-binding membrane glycoproteins, the 170 kDa P-glycoprotein (P-gp) and the 190 kDa multidrug resistance protein (MRP), are involved in the acquisition of multidrug resistance phenotypes in cancer cells. Overexpression of P-gp is often observed in various human tumors when treated with anticancer agents. In this study, we asked whether MRP was overexpressed in human gliomas after cancer chemotherapy. We investigated expression of MRP and P-gp before and after chemotherapy in tumor samples from patients with glioma. MRP expression was observed in 16 (70%) of 23 untreated patients, and the proportion of MRP-positive cells in the whole cell population ranged from 3 to 32% in the 16 MRP-positive patients. P-gp-positive tumors were observed in 4 (18%) of 23 patients, and the proportional rates of P-gp-positive cells in the whole cell population ranged from 4 to 23%. The proportional rate of MRP-positive or P-gp-positive glioma cells increased after chemotherapy when compared with that before chemotherapy in all patients examined. We could observe no statistically significant correlation between expression of MRP or P-gp and tumor grade. These results suggest that MRP as well as P-gp may be involved in acquired or intrinsic drug resistance in human glioma.

Abstract
Intrinsic or acquired drug resistance is a major limiting factor of the effectiveness of chemotherapy. Increased expression of either the MRP gene or the MDR1 gene has been demonstrated to confer drug resistance in vitro. In this study, we examined MRP and MDR1 gene expression in a panel of 17 small cell lung cancers (SCLC) xenografted into nude mice from treated and untreated patients using an RT-PCR technique. For some of them, the outcome of the corresponding patients was known and we related MDR1/MRP expression with the xenograft response to C'CAV (cyclophosphamide, cisplatin, adriamycin and etoposide) combined chemotherapy. Fifteen (88%) of the 17 cases of SCLC were found to be positive for either MDR1 or MRP. MRP gene expression was present in 12 (71%) of 17 cases, whereas MDR1 gene expression was detected in eight (50%) of 16 cases. For six SCLC, the survival duration of patients differed, with three patients surviving for more than 30 months after therapy. Among these six turnours, five expressed MRP and/or MDR1. These six xenografts responded to the C'CAV treatment but a significant rate of cure was obtained in only three cases. No obvious relationship was observed between the response to this treatment and MRP or MDR1 expression. However, the remarkably high levels and frequency of MRP expression in some SCLC samples indicate that future developments in chemotherapy of this tumour type should anticipate that drugs which are substrates of MRP may be of limited effectiveness.

Abstract
KB/7D cells represent a multidrug-resistant subclone of human nasopharyngeal carcinoma KB cells generated by continuous exposure to the topoisomerase II inhibitor VP-16 (etoposide). KB/7D cells also show cross-resistance to doxorubicin and vincristine. Phenotypic traits of the cell line include a 2-fold decrease in topoisomerase II levels and a decrease in the uptake of VP-16 without an increase in the rate of drug efflux or expression of P-glycoprotein, suggesting a novel mechanism associated with the uptake of anticancer drugs. This study demonstrated that the multidrug-resistance associated protein (MRP) is overexpressed in KB/7D cells, and that the loss of resistance in revertant cells correlates with the loss of MRP. The resistance to VP-16 and doxorubicin could be overcome, partially, and resistance to vincristine could be overcome completely, by the L-enantiomer of verapamil, but not by the D-enantiomer or by BIBW 22 (4-[N-(2-hydroxy-2-methyl-propyl)-ethanolamino]-2,7-bis[cis-2,6-++ +dimethylmorpholino)-6-phenylpteridin), an inhibitor of MDR-1. L-Verapamil was shown to be significantly more potent than D-verapamil in modulating the accumulation defect in KB/7D cells towards doxorubicin, as measured by flow cytometry and confocal microscopy, and towards VP-16, as measured by increases in protein-linked DNA strand breaks. This suggests that KB/7D cells are multidrug resistant due to decreases in topoisomerase II levels and the overexpression of MRP, that MRP leads to a decrease in drug accumulation, and that L-verapamil can modulate the MRP-associated accumulation defect and drug-resistance phenotype. This contrasts with previous studies that suggest that MRP causes multidrug resistance by exporting cytotoxic drugs out of the cell and that did not show modulation of MRP by verapamil.

Abstract
DNA topoisomerases are major defined targets for a large variety of clinically important anticancer agents, including etoposide, adriamycin, and mitoxantrone. Mutations at amino acids 439, 450 and 803 of DNA topoisomerase II were examined in multiple anticancer drug-resistant anaplastic thyroid carcinomas (ten cell lines and three cancerous tissues) by reverse transcriptase-polymerase chain reaction (RT-PCR) and subsequent DNA sequencing. No mutation was found in these cell lines and tissues, but mdr1, mrp and/or lrp mRNA were expressed to a varying degree, and there was no significant difference in DNA topoisomerase IIalpha content among the cell lines and tissues as evaluated by Western blotting. Our experimental data indicate that overexpression of multidrug resistance-related mRNA is sufficient to confer drug resistance.

Abstract
1. Multidrug resistance (MDR) is a phenomenon originally seen in cultured tumor cells that, following selection for resistance to a single anticancer agent, become resistant to a range of chemically diverse anticancer agents. These MDR cells show a decrease in intracellular drug accumulation due to active efflux by transporter proteins. The transporter best characterized is P-glycoprotein (Pgp). This protein has been identified in many cancers and has been the target for agents able to inhibit its action, thereby reversing resistance. 2. More recently, another transporter, multidrug resistance-associated protein (MRP) has been identified in a number of MDR human tumor cell lines that do not apparently express Pgp. The presence of MRP at the cell surface of these cells is associated with alterations in drug accumulation and distribution. 3. The gene-encoding MRP has been cloned and sequenced and shown by transfection studies to be able to confer resistance and changes in drug accumulation in sensitive tumor cells. The profile of anticancer drugs expelled in the presence of MRP is similar, but not identical, to that of Pgp. 4. MRP has been identified in a number of different types of cancers, but it is not yet clear to what extent it is involved with clinical resistance. Furthermore, resistance modulators useful against Pgp are less effective in reversing MRP-mediated resistance. 5. It is not fully understood how MRP brings about drug efflux, but it is clear that the underlying mechanisms are different from those responsible for Pgp-mediated drug efflux. In particular, glutathione (GSH) is required for the effective expulsion of the anticancer agents. 6. Unlike Pgp, MRP is able to transport metallic oxyanions and glutathione and other conjugates, including peptidyl leukotrienes. Agents that inhibit organic anion transport, such as probenecid, can block MRP activity. 7. Like Pgp, MRP is expressed not only in resistant tumor cells, but also in normal human tissues. These include the epithelial cells lining the airways and the gastrointestinal tract. In cells in normal tissues, MRP appears to be located within the cytoplasm, which may mean that it functions here in a manner slightly different to that in malignant cells. It is now also recognized in cells and tissues from other species, such as the rat and mouse.

Abstract
We evaluated the expression of MDR1/p-glycoprotein in paediatric tumours using reverse transcriptase polymerase chain reaction (RT-PCR), RNA dot blot analysis, and immunohistochemistry on formalin fixed paraffin-embedded material with JSB-1 and C-219 monoclonal antibodies, and compared these three techniques. The expression of multidrug resistance-associated protein (MRP) gene was examined by RT-PCR assay. We studied MDR1/p-glycoprotein and MRP expression in 13 samples from 10 neuroblastoma patients, 11 samples from 10 nephroblastoma patients, 2 rhabdomyosarcomas, 1 adrenocortical carcinoma and 10 benign tumours or tumour-like lesions. Eleven of 13 neuroblastomas, 7 of 11 nephroblastomas, 2 rhabdomyosarcomas, 1 adrenocortical carcinoma, and 7 of 10 benign tumours or tumour-like lesions showed MDR1 PCR products. By RNA dot blot analysis, MDR1 transcripts were detectable in 11 of 34 specimens. Immunohistochemically, we detected positive reaction products for JSB-1 in 26 of 36 samples. There was a significant correlation between the immunoreactivity for JSB-1 and the expression of MDR1 mRNA expression by RT-PCR (P = 0.0001). However, the presence of p-glycoprotein immunostaining does not correlate with the MDR1 expression shown by RT-PCR in every case. As for MRP mRNA expression, 9 of 13 neuroblastomas and 10 of 11 nephroblastomas revealed PCR products.

Abstract
MDR1 (P-glycoprotein), multidrug resistance-associated protein (MRP) and lung resistance protein (LRP) are associated with multidrug resistance in various cancer cells. It is known that P-glycoprotein and MRP are also expressed in several normal tissues. However, the exact location of LRP in normal tissues is still unclear. In order to obtain more insight into the physiological role of LRP, its expression in human normal tissues was examined by an immunohistochemical technique, using one monoclonal antibody, LRP-56. Reverse transcriptase-polymerase chain reaction (RT-PCR) was also utilized for several cell lines and fresh-frozen tissues. P-glycoprotein was found to be expressed in the kidney, adrenal, brain vessels, muscle, lung, pancreas, liver, intestine, placenta and testis. MRP was expressed in the kidney, adrenal, lung, pancreas, muscle, intestine, thyroid and prostate, and its distribution mostly overlapped with that of P-glycoprotein. Interestingly, MRP was not expressed in the liver. LRP at 110 kDa was expressed in the kidney, adrenal, heart, lung, muscle, thyroid, prostate, bone marrow and testis. These findings suggest that LRP as well as P-glycoprotein and MRP plays distinct roles in the physiology of various organs.

Abstract
The expression of multidrug resistance-associated protein (MRP) mRNA was examined in ten samples of Ewing's sarcoma of bone (ES) and in one nude mice transplantable ES and two malignant peripheral neuroectodermal tumor (MPNT) cell lines using an RT-PCR assay. MRP mRNA expression was recognized in eight of the ten clinical specimen and in all three cell lines. On the other hand, the expression of multidrug resistance gene (MDR1) was demonstrated in three of the ten clinical samples and all three cell lines. Our results may contribute to elucidation of the mechanism of anti-cancer-drug resistance in this tumor.

Abstract
Complementary DNA clones encoding a novel protein, ABC-C, with the typical structural features of the ABC transporter family were identified in a human medullary thyroid carcinoma cell line. The transporter consists of 1704 amino acid residues with two homologous repeats, each harboring six putative transmembrane helices and an ATP-binding cassette motif. The mRNA is expressed highest in normal lung, but also in varying amounts in other tissues and in C-cell carcinoma. The ABC-C gene is mapped on chromosome 16p13.3, in close physical proximity to another ABC transporter, the multidrug resistance-associated protein. This related protein is assumed to confer resistance to chemotherapeutic drugs in small cell lung carcinoma. The genomic clustering of both transporters, typical also for other members of the ABC family, supports the notion that ABC-C may be involved in development of resistance to xenobiotics.

Abstract
We examined the mRNA expression of the multidrug- resistance-associated protein gene (MRP) in soft-tissue sarcomas and compared it with the expression of the multidrug resistance gene (MDR1), using the reverse transcriptase/polymerase chain reaction. We investigate 39 samples from 33 cases of soft-tissue sarcomas (11 liposarcomas, 9 malignant fibrous histiocytomas, 6 leiomyosarcomas, 4 malignant schwannomas, 3 fibrosarcomas, 3 synovial sarcomas, and 3 epithelioid sarcomas) and 7 benign soft-tissue tumors. All samples were obtained prior to chemotherapy. An expression of MRP mRNA was noted in 56% of soft-tissue sarcoma specimens. The co-expression of MRP and MDR1 was recognized in 15 samples (38%) (5/11 liposarcomas, 5/9 malignant fibrous histiocytomas, 3/6 leiomyosarcomas, 2/3 fibrosarcomas) and significantly correlated with histological grade (P=0.0165). A positive and significant correlation was found between MRP and MDR1 expression in soft-tissue sarcomas(P=0.0013). In benign soft-tissue tumors, 1 chemodectoma and 1 neurothekeoma showed low MRP expression; however, no case showed co-expression of MRP and MDR1.

Abstract
The expression of multidrug-resistance-associated protein (MRP) was assessed in various types of untreated lung cancer using an immunohistochemical technique. MRP was abundantly expressed in 28 of 59 adenocarcinoma specimens (47%) and its expression was associated with the degree of glandular differentiation of the tumor. MRP expression in well-differentiated adenocarcinomas (56%) was higher than in poorly differentiated adenocarcinomas (22%) (p < 0.01). lower--20% in squamous-cell carcinomas, 20% in large-cell carcinomas and 0% in small-cell carcinomas and carcinoids. RT-PCR showed that the MRP-positive adenocarcinomas and squamous-cell carcinomas expressed mrp mRNA significantly. Immunoelectron microscopically, MRP was localized in the plasma membrane and rough endoplasmic reticulum. It is thus important to take MRP into account when considering chemotherapy for lung cancers because levels of mdr I gene product, another multidrug-resistance gene family, are low in untreated lung cancers.

Abstract
It was found that the mechanism of anti-cancer drug resistance in anaplastic carcinoma of the thyroid was not explicable only in terms of expression of mdr1 and its gene product, P-glycoprotein. The multidrug resistance-associated protein (MRP), another member of the mdr gene family, may be involved in anti-cancer drug resistance of this carcinoma. The MRP expression was examined immunohistochemically in 8 cell lines and 73 thyroid cancer tissues; its frequency in anaplastic carcinoma (52%) was significantly higher than that in other thyroid cancer types.
