However, histopathological examination revealed a positive surgical margin, therefore, additional transanal excision was performed with endoscopic submucosal dissection, and the residual cancer tissue was completely resected.

[Decision-Making Regarding Adjuvant Therapy for Hormone Receptor-Positive, HER2-Negative Early Breast Cancer].

In December 2021, abemaciclib was approved as an adjuvant treatment for hormone receptor-positive, HER2-negative, high-risk early breast cancer in Japan. The Oncotype DX Breast Cancer Recurrence Score program(Oncotype DX)is a test that can be used to limit overtreatment in hormone receptor-positive, HER2-negative, low-risk early breast cancer. Although the target groups of both these are different and usually without many overlapping indications, we encountered a case in which this therapy and test were used in a short time period.

Nucleotide substitutions in CD101, the human homolog of a diabetes susceptibility gene in non-obese diabetic mouse, in patients with type 1 diabetes.

Aims/introduction: Although genome-wide association studies have identified more than 50 susceptibility genes for type 1 diabetes, low-frequency risk variants could remain unrecognized. The present study aimed to identify novel type 1 diabetes susceptibility genes by newly established methods.

Materials And Methods: We carried out whole-exome sequencing and genome-wide copy-number analysis for a Japanese family consisting of two patients with type 1 diabetes and three unaffected relatives.

Molecular mechanisms of transcriptional regulation by the nuclear zinc-finger protein Zfat in T cells.

Zfat is a nuclear protein with AT-hook and zinc-finger domains. We previously reported that Zfat plays crucial roles in T-cell survival and development in mice. However, the molecular mechanisms whereby Zfat regulates gene expression in T cells remain unexplored.

Sequential hydroxylation of vitamin D2 by a genetically engineered CYP105A1.

Our previous studies revealed that the double variants of CYP105A1- R73A/R84A and R73V/R84A-show high levels of activity with respect to conversion of vitamin D3 to its biologically active form, 1α,25-dihydroxyvitamin D3 (1α,25(OH)2D3). In this study, we found that both the double variants were also capable of converting vitamin D2 to its active form, that is, 1α,25-dihydroxyvitamin D2 (1α,25(OH)2D2), via 25(OH)D2, whereas its 1α-hydroxylation activity toward 25(OH)D2 was much lower than that toward 25(OH)D3. Comparison of the wild type and the double variants revealed that the amino acid substitutions remarkably enhanced both 25- and 26-hydroxylation activity toward vitamin D2.

Human genetic variation database, a reference database of genetic variations in the Japanese population.

Whole-genome and -exome resequencing using next-generation sequencers is a powerful approach for identifying genomic variations that are associated with diseases. However, systematic strategies for prioritizing causative variants from many candidates to explain the disease phenotype are still far from being established, because the population-specific frequency spectrum of genetic variation has not been characterized. Here, we have collected exomic genetic variation from 1208 Japanese individuals through a collaborative effort, and aggregated the data into a prevailing catalog.

Gene expression profiling of white adipose tissue reveals paternal transmission of proneness to obesity.

Previously, we found that C57BL/6J (B6) mice are more prone to develop obesity than PWK mice. In addition, we analyzed reciprocal crosses between these mice and found that (PWK × B6) F1 mice, which have B6 fathers, are more likely to develop dietary obesity than (B6 × PWK) F1 mice, which have B6 mothers. These results suggested that diet-induced obesity is paternally transmitted.
