In this study, a transformation system enabling large-scale gene recombination was developed for the hyperthermophilic archaeon Thermococcus kodakarensis. Using the uracil auxotroph T. kodakarensis KU216 (∆pyrF) as a parent strain, we constructed multiple host strains harboring two 1-kbp DNA regions from the genomes of either the hyperthermophilic archaeon Pyrococcus furiosus or Methanocaldococcus jannaschii. The two regions were selected so that the regions between them on the respective genomes would include pyrF genes, which can potentially be used for selection. Transformation using these host strains and genomic DNA from P. furiosus or M. jannaschii were carried out. Transformants with exogenous pyrF were obtained only using host strains with regions from P. furiosus, and only when the distances between the two regions were relatively short (2-5 kbp) on the P. Filanesib solubility dmso furiosus genome. To insert longer DNA fragments, we examined the possibilities of using P. furiosus cells to provide intact genomic DNA. A cell pellet of P. furiosus was overlaid with that of T. kodakarensis so that cells were in direct contact. As a result, we were able to isolate T. kodakarensis strains harboring DNA fragments from P. furiosus with lengths of up to 75 kbp in a single transformation step.Public knowledge of medical genetics is essential for better establishment of its services but has been rarely evaluated based on distinguished types of knowledge. We designed and validated a new self-administered questionnaire in Farsi (Persian language) to assess public knowledge of medical genetics based on Rogers' framework. This framework divides knowledge into three types of awareness, how-to (practical) and principles knowledge which refer to knowing the existence, proper use, and theoretical principles of an innovation, respectively. We asked consecutive individuals (n = 306, age ≥ 20 years) visiting health centers in different regions of Yazd, a city in central Iran, to fill out the questionnaire. After validation, we analyzed 280 of the questionnaires which revealed a high degree of internal consistency (Cronbach's alpha 0.90) and a positive linear relationship among the scores of different knowledge. Our respondents had relatively fair awareness and how-to, but generally poor principles knowledge with statistically significantly better scores in females and those with higher education. We observed tangible strengths in topics such as consanguineous marriage, thalassemia, and hereditary predisposition to diabetes and cardiovascular disorders, and weaknesses in areas such as genetic testing and genetics of cancer. Notably, experience of premarital genetic counseling did not show any significant effect, but having a relative with a genetic disorder was significantly linked to better awareness scores. Our study provides a reliable and self-administered questionnaire for the assessment of public knowledge of medical genetics. Despite revealing important strengths and weaknesses in our population sample, larger scale evaluations in Iran and other developing countries are needed for better understanding of the public knowledge as the prerequisite for designing appropriate educational programs.DOCK10, a guanine-nucleotide exchange factor (GEF) for Rho GTPases, represents the example of a gene that gives rise to alternative first exon mRNA isoforms, named DOCK10.1 and DOCK10.2. Expression of human DOCK10.2 protein in cell lines, and its induction by interleukin-4 (IL-4) in normal B lymphocytes and chronic lymphocytic leukemia (CLL) cells, were previously demonstrated using an antiserum raised against a peptide encoded by sequences from exon 1.2. Here, expression of human DOCK10.1 protein was demonstrated using an antiserum raised against a peptide encoded by sequences from exon 1.1. Specificity of the DOCK10.1 and DOCK10.2 antisera for their respective isoforms was demonstrated using transfected human 293 T cells. Their specificity for endogenous DOCK10 was strongly suggested by the high significance of the correlations between the levels of their expected signals at the molecular size of 250 kDa and the levels of DOCK10.1 and DOCK10.2 mRNAs, respectively, in human hematopoietic cell lines. Specificity of the DOCK10.1 antiserum for DOCK10 was also demostrated in mouse using the DOCK10 knockout model. The DOCK10.1 protein was induced by IL-4 in CLL cells, which demonstrates that the mechanism by which IL-4 regulates DOCK10 is not isoform-specific. Last, to get insights into differential regulation of the DOCK10 isoforms, their protein levels in cell lines were compared with their gene expression profiles retrieved from the Cancer Cell Line Encyclopedia (CCLE), leading to the identification of BCL3 and KLF12 as potential transcriptional regulators of DOCK10.1 and DOCK10.2, respectively.The cell cycle is a complex and strictly controlled process, consisting of different phases. Cell cycle regulation depends on phase-specific transcriptions of cell cycle genes. The alterations of cell cycle genes can predispose normal cells to have a cancerous phenotype. Indeed, several mechanisms underlying the deregulation of the cell cycle have been identified in different types of cancer. Cancer stem cells (CSCs), a fraction of tumor cells, are selectively capable of initiating tumor development. However, the deregulation of the cell cycle progression in CSCs still remains incompletely understood. This review describes epigenetic alterations and aberrant transcriptional regulation of cell cycle genes in CSCs as well as cell cycle patterns of CSCs.Due to the depletion of fossil fuel resources and concern about increasing atmospheric CO2 levels, the production of microbial oil as source for energy and chemicals is considered as a sustainable alternative. A promising candidate strain for the production of microbial oil is the oleaginous yeast Schwanniomyces occidentalis CBS 2864. To compete with fossil resources, cultivation and processing of S. occidentalis requires improvement. Currently, different cell wall disruption techniques based on mechanical, chemical, physiological, and biological methods are being investigated using a variety of oil producing yeasts and microalgae. Most of these techniques are not suitable for upscaling because they are technically or energetically unfavorable. Therefore, new techniques have to be developed to overcome this challenge. Here, we demonstrate an effective mild enzymatic approach for cell disruption to facilitate lipid extraction from the oleaginous yeast S. occidentalis. Most oil was released by applying 187 mg L-1 tailor-made enzymes from Trichoderma harzianum CBS 146429 against the yeast cell wall of S.
