The Human Genome Project is now almost completed, and we are about to move into the post-genome sequence era of functional genomics. The advent of genome science has markedly changed the way life science research including pharmacological study is conducted; thus, systematic and integrated 'genome-wide' survey is feasible. The stream of 'Genome-->Transcriptome--> Proteomics' is logical and, in each aspect, approaches for functional genomics are now pursued at a high pace. We have recently developed a standardized technical platform (in various levels, such as transcription, cell and whole animal levels, etc.), and applied these techniques to the study of functional genomics of G-protein-coupled receptors, particularly alpha1-adrenoceptors as a model. Combining the genome information and technology, future pharmacological studies would become the genome-based search and research.

Acute physical exercise and ambulatory blood pressure in resistant hypertension.
J Hypertens
November 2024
Faculty of Sport Sciences, Universidad Europea de Madrid.
Objectives: The effects of acute physical exercise in patients with resistant hypertension remain largely unexplored compared with hypertensive patients in general. We assessed the short-term effects of acute moderate-intensity (MICE) and high-intensity interval exercise (HIIE) on the clinic (BP) and 24-h ambulatory blood pressure (ABP) of patients with resistant hypertension.
Methods: Using a crossover randomized controlled design, 10 participants (56 ± 7 years) with resistant hypertension performed three experimental sessions: MICE, HIIE, and control.
Actionable Gene Alterations Identified in Patients With Malignant Melanoma by Targeted Sequencing in Japan.
JCO Precis Oncol
January 2025
Department of Medical Oncology, Hokkaido University Hospital, Sapporo, Hokkaido, Japan.
Purpose: Precision medicine plays an important role in the treatment of patients with advanced melanoma. Despite its high incidence in White patients, advanced melanoma is rare in Asian countries, hampering prospective clinical trials targeting the Asian population. This retrospective study aimed to elucidate the real-world molecular diagnoses and outcomes of Japanese patients with melanoma using comprehensive genome profiling (CGP).

Background And Objectives: Breast cancers (BCs) of patients with paraneoplastic neurologic syndromes and anti-Yo antibodies (Yo-PNS) overexpress human epidermal growth factor receptor 2 (HER2) and display genetic alterations and overexpression of the Yo-onconeural antigens. They are infiltrated by an unusual proportion of B cells. We investigated whether these features were also observed in patients with PNS and anti-Ri antibodies (Ri-PNS).

Recent studies in vertebrates and Caenorhabditis elegans have reshaped models of how the axon guidance cue UNC-6/Netrin functions in dorsal-ventral axon guidance, which was traditionally thought to form a ventral-to-dorsal concentration gradient that was actively sensed by growing axons. In the vertebrate spinal cord, floorplate Netrin1 was shown to be largely dispensable for ventral commissural growth. Rather, short range interactions with Netrin1 on the ventricular zone radial glial stem cells was shown to guide ventral commissural axon growth.

The green seaweed relies on associated bacteria for morphogenesis and is an important model to study algal-bacterial interactions. -associated bacteria exhibit high turnover across environmental gradients, leading to the hypothesis that bacteria contribute to the acclimation potential of the host. However, the functional variation of these bacteria in relation to environmental changes remains unclear.
