Mouse Mtfr1l Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Mtfr1l Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Mtfr1l conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Mtfr1l gene (NCBI Reference Sequence: NM_001256112 ; Ensembl: ENSMUSG00000046671 ) is located on Mouse chromosome 4. 7 exons are identified, with the ATG start codon in exon 2 and the TGA stop codon in exon 7 (Transcript: ENSMUST00000102550). Exon 4~6 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Mtfr1l gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-288M17 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 4 starts from about 13.96% of the coding region. The knockout of Exon 4~6 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 1354 bp, and the size of intron 6 for 3'-loxP site insertion: 2576 bp. The size of effective cKO region: ~2201 bp. The cKO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(8701bp) | A(24.37% 2120) | C(23.18% 2017) | T(28.27% 2460) | G(24.18% 2104) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

Although hijacking of the host cellular pathway is fundamental for developing a better understanding of the human papillomavirus (HPV) pathogenesis, a major obstacle is identifying the central molecular targets involved in HPV-driven CC.

Received: 2021.01.13; Accepted: 2021.04.15; Published: 2021.04.26 Abstract Background: Mitochondrial fission regulator 2 (MTFR2) which can promote mitochondrial fission, has recently been reported to be involved in tumorigenesis. However, little is known about its expression levels and function in gastric cancer (GC). This study aims to clarify the role of MTFR2 in GC.

  • Global Characterization of the Immune Response to Inoculation of Aluminium Hydroxide-Based Vaccines by Rna Sequencing
    GLOBAL CHARACTERIZATION OF THE IMMUNE RESPONSE TO INOCULATION OF ALUMINIUM HYDROXIDE-BASED VACCINES BY RNA SEQUENCING Endika Varela Martínez Supervisor: B.M. Jugo Euskal Herriko Unibertsitatea / Universidad del País Vasco 2020 (c)2020 Endika Varela Martínez i Acknowledgments I would like to thank my supervisor Begoña M. Jugo for her constant support and guidance through my PhD project. I am thankful to the postdoctoral researcher Naiara Abendaño and the fellow PhD student Martín Bilbao for promoting and maintaining a cordial working environment and for their contributions. This work would have not been possible without the collaboration of the research group directed by Dr. L LLuján in the Department of Animal Pathology in the University of Zaragoza and the research team directed by Dr. D de Andrés in the Institute of Agrobiotechnology (IdAB) in Mutilva, Navarra. Despite being a sort stay, I would like to express my appreciation to Dr. Jan Gorodkin and other members of the Center for non-coding RNA in Technology and Health (RTH) from the University of Copenhagen, Denmark. Working with that team has been a great privilege and I have learned a great deal about circular RNAs (circRNAs) and their annotation, apart to be an opportunity to learn about Denmark and more specifically about Copenhagen. Last but not least, I dedicate this thesis to my family. Most of all, to my parents and brother who have supported me through these years and specially to my grandmother for her continuous and unparalleled love and encouragement. Funding This thesis is the result of my PhD project carried out from November 2015 to ______ 2020 at the Department of Genetics, Physical Anthropology and Animal Physiology, University of the Basque Country (UPV/EHU).

Scale bar = 20um. Supplemental Fig. 2: Scatter plots displaying the correlation between tumor of origin and PDX DNA. Left: Tumor of origin v. patient derived xenograft (PDX) variant allele frequency (VAF) plots. Variance is in relation to the identity line, therefore, points along axis reflect evidence of heterogeneity. Right: Simple X/Y scatterplots showing raw counts gene expression levels of each tumor compared to its respective xenograft. The correlation coefficients (on a scale of 0 to 1) are included underneath. Supplemental Fig. 3: A) Heatmap of eight parental tumor samples with list of all genes.
