Nuclear translocation of ATBF1 is a potential prognostic maker for skin cancer

The AT motif binding factor 1 (ATBF1) is expressed in varioustissues, such as brain, liver, lung, and gastrointestinal tract, and hasan important role in cell differentiation in organs. ATBF1 interacts withPIAS3, a protein inhibitor for activated signal transducer and activatorof transcription (STAT3), to suppress STAT3 signaling, which has criticalroles in cell proliferation, migration, and survival. We hypothesized thatATBF1 is a useful prognostic marker for skin cancer. We performed immunohistochemicalanalyses of squamous cell carcinoma (SCC, n=7),basal cell carcinoma (BCC, n=4), and Bowen’s disease (n=4) tissues usingan anti-ATBF1 monoclonal antibody. All cases of BCC and Bowen’sdisease exhibited intense nuclear ATBF1 staining, whereas only someSCC cases exhibited weakly positive nuclear ATBF1 staining. SCC andBowen’s disease showed intense nuclear STAT3 staining, while BCC hadfew STAT3-positive nuclei. Based on these observations, nuclear ATBF1staining was associated with low malignancy profiles. The pattern ofATBF1 staining is a potential prognostic marker for skin cancer

Full-Length Sequence of Mouse Acupuncture-Induced 1-L (Aig1l) Gene Including Its Transcriptional Start Site

We have been investigating the molecular efficacy of electroacupuncture (EA), which is one type of acupuncture therapy. In our previous molecular biological study of acupuncture, we found an EA-induced gene, named acupuncture-induced 1-L (Aig1l), in mouse skeletal muscle. The aims of this study consisted of identification of the full-length cDNA sequence of Aig1l including the transcriptional start site, determination of the tissue distribution of Aig1l and analysis of the effect of EA on Aig1l gene expression. We determined the complete cDNA sequence including the transcriptional start site via cDNA cloning with the cap site hunting method. We then analyzed the tissue distribution of Aig1l by means of northern blot analysis and real-time quantitative polymerase chain reaction. We used the semiquantitative reverse transcriptase-polymerase chain reaction to examine the effect of EA on Aig1l gene expression. Our results showed that the complete cDNA sequence of Aig1l was 6073 bp long, and the putative protein consisted of 962 amino acids. All seven tissues that we analyzed expressed the Aig1l gene. In skeletal muscle, EA induced expression of the Aig1l gene, with high expression observed after 3 hours of EA. Our findings thus suggest that the Aig1l gene may play a key role in the molecular mechanisms of EA efficacy

A Homozygous Mutation in UGT1A1 Exon 5 May Be Responsible for Persistent Hyperbilirubinemia in a Japanese Girl with Gilbert’s Syndrome

The UGT1A1 gene encodes a responsible enzyme, UDP-glucuronosyltransferase1A1, for bilirubin metabolism. Many mutations have already been identified in patients with inherited disorders with hyperbilirubinemia, Crigler-Najjar syndrome and Gilbert’s syndrome. In this study, we identified a UGT1A1 mutation in an 8-year-old Japanese girl with persistent hyperbilirubinemia who was clinically diagnosed as having Gilbert’s syndrome. For the mutational analysis of UGT1A1, we performed a full sequence analysis of the gene using the patient’s DNA. She was homozygous for a T to G transversion at nucleotide position 1456 in UGT1A1 exon 5 (c.1456T>G), leading to the substitution of aspartate for tyrosine at position 486 of the UGT1A1 protein (p.Y486D). In conclusion, the homozygous mutation of UGT1A1 may be responsible for persistent hyperbilirubinemia in this patient

The influence of melt infiltration on the Li and Mg isotopic composition of the Horoman Peridotite Massif

We have analysed the Li and Mg isotope ratios of a suite of samples from the Horoman peridotite massif. Our results show that most Li and all Mg isotopic compositions of the Horoman peridotites are constant over 100 metres of continuous outcrop, yielding values for pristine mantle of δ7Li = 3.8 ± 1.4 ‰ (2SD, n = 9), δ25Mg = -0.12 ± 0.02 ‰ and δ26Mg = -0.23 ± 0.04 ‰ (2SD, n = 17), in keeping with values for undisturbed mantle xenoliths. However, there are also some anomalously low δ7Li values (-0.2 to 1.6 ‰), which coincide with locations that show enrichment of incompatible elements, indicative of the prior passage of small degree melts. We suggest Li diffused from the infiltrating melts with high [Li] into the low [Li] minerals and kinetically fractionated 7Li/6Li as a result. Continued diffusion after the melt flow had ceased would have resulted in the disappearance of this isotopically light signature in less than 15 Ma. In order to preserve this feature, the melt infiltration must have been a late stage event and the massif must have subsequently cooled over a maximum of ∼0.3 Ma from peak temperature (950°C, assuming the melts are hydrous) to Li closure temperature (700°C), likely during emplacement. The constant δ26Mg values of Horoman peridotites suggest that chemical potential gradients caused by melt infiltration were insufficient to drive associated δ26Mg fractionation greater than our external precision of 0.03 ‰

The Japanese Society of Pathology Practical Guidelines on the handling of pathological tissue samples for cancer genomic medicine

Clinical cancer genomic testing based on next-generation sequencing can help select genotype-matched therapy and provide diagnostic and prognostic information. Pathological tissue from malignant tumors obtained during routine practice are frequently used for genomic testing. This article is aimed to standardize the proper handling of pathological specimens in practice for genomic medicine based on the findings established in "Guidelines on the handling of pathological tissue samples for genomic medicine (in Japanese)" published by The Japanese Society of Pathology (JSP) in 2018. The two-part practical guidelines are based on empirical data analyses; Part 1 describes the standard preanalytic operating procedures for tissue collection, processing, and storage of formalin-fixed paraffin-embedded (FFPE) samples, while Part 2 describes the assessment and selection of FFPE samples appropriate for genomic testing, typically conducted by a pathologist. The guidelines recommend that FFPE sample blocks be used within 3 years from preparation, and the tumor content should be >= 30% (minimum 20%). The empirical data were obtained from clinical studies performed by the JSP in collaboration with leading Japanese cancer genome research projects. The Japanese Ministry of Health, Labour, and Welfare (MHLW) recommended to comply with the JSP practical guidelines in implementing cancer genomic testing under the national health insurance system in over 200 MHLW-designated core and cooperative cancer genome medicine hospitals in Japan
