It has been confirmed that when circulating Prostate Specific Antigen (PSA) transcripts are successfully detected, prostate cancer cells can be diagnosed at an early stage. A reverse transcriptase loop-mediated isothermal amplification (RT-LAMP) assay was developed and compared to reverse transcriptase polymerase chain reaction (RT-PCR) assay for detection of PSA. Methods: 47 patients, including 30 patients with prostate cancer, 15 with Benign Prostate Hyperplasia (BPH) and 2 healthy subjects as negative controls were included in this study. The prostate cancer cell lines (PC3 and LNCaP) of two patients were included in the study as positive controls. Next, RNA was extracted from fresh samples and a first strand cDNA synthesis kit was applied for the synthesis of cDNA. The human prostate specific antigen gene was used to design specific primers. Results: The results indicated that the control subjects and participants suffering from BPH were not positive. 13 out of 15 (86.6%) patients suffering from localized cancer were PSA positive. PSA positive results were observed among all 15 metastatic patients and positive controls (100%). RT-LAMP is an advantageous method because it is highly sensitive (1000-fold), quite cheap, user-friendly, and safe; in addition, it can be quickly performed by visual detection using GineFinderTM dye in a water bath. Conclusion: RT-LAMP technique can be simply and reliably applied with the aid of basic instruments, and its results can be visually inspected in laboratory studies.","PeriodicalId":8706,"journal":{"name":"Basic & Clinical Cancer Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79505020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of molecular studies (such as RNA expression analysis) aids the characterization of this cancer, the development of new targets for therapy, and the introduction of novel prognostic and diagnostic biomarkers. Recent studies have confirmed Mammalian Sterile 20-Like kinase (MST1) as a tumor suppressor gene, which has been introduced as a biomarker for some specific cancers. In this study, we focus on MST1 expression levels in the WBC of PC patients, due to the inheritance pattern of PC. Methods: This case-control study was conducted in two groups (20 patients with PC and 20 healthy individuals). After RNA extraction and cDNA synthesis, quantitative Real-Time PCR was done in order to determine the MST1 expression level. GAPDH was selected as an internal control gene. Statistical analysis was performed using “Rotor-Gene Q series software 2.3.1” and “Rest 2.0.13 software”. Results: This study, carried out on 20 PC patients aged 50-70 and 20 healthy individuals shows that MST1 expression level in the WBC samples of PC patients is approximately 62% lower compared to normal individuals (P<0.01). Conclusion: Introducing the reduced expression level of MST1 as a prostate cancer biomarker requires complementary research. However, in this study, biomarker validation and potential of MST1 has been approved.","PeriodicalId":8706,"journal":{"name":"Basic & Clinical Cancer Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90805082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To have the best control when heating tissues in hyperthermia, the use of magnetic nanoparticles is suggested. The local control of heat is very important in this technique, to prevent the damage of healthy tissues around the tumor, and therefore it is necessary to measure changes in temperature to determine the optimum conditions in which hyperthermia can create the desired results. The type and concentration of nanoparticles and nanoparticle distribution within the cancerous tissue are key factors affecting temperature distribution throughout the hyperthermia process. One of the main factors influencing nanoparticle distribution is the characteristics of the diffusion media, such as chemical composition, morphological and mechanical features, all of which affect the diffusion of nanoparticles at the cancer site. In this review, the most common in vitro and in vivo media and their influence on the results of hyperthermia are discussed. We also mention in silico as a computational model. Buffer solutions, cell cultures, microfluids, dead tissues and animal models are some of the in vitro media that are discussed in this review paper. In addition, some of the animal models used for hyperthermia will be mentioned.","PeriodicalId":8706,"journal":{"name":"Basic & Clinical Cancer Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73090744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since this technology has not yet been launched for patients at the Cancer Institute of Imam Khomeini Hospital harboring gene mutations that predispose patients to breast cancer, this study aimed to introduce a PGD-based model using a single cell lymphocyte instead of an embryonic blastomere. Methods: Two affected and unrelated women with a known mutation in BRCA1/2 were enrolled in this study. Each patient (together with her siblings) was considered as an embryo derived from a hypothetical couple. Blood samples were collected from these individuals as well as their parents. Linkage analysis was performed. Following this process, a mutation-free individual and a mutation carrier was selected from the first and second family, respectively. A single lymphocyte was then extracted from their freshly taken peripheral blood, and afterwards Nested Multiplex PCR was performed. Results: PGD confirmed that the individual from the first family is free of a mutation and the second one is a pathogenic mutation carrier. Conclusion: Our results suggested that PGD is a viable choice to offer to families with \"Hereditary Breast Cancer Syndrome\", who have been diagnosed with a known pathogenic mutation. Our introduced model can be used as a possible option by other laboratories that are planning to launch this technology.","PeriodicalId":8706,"journal":{"name":"Basic & Clinical Cancer Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78608689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
