A systematic effort to isolate kidney-specific genes was performed using recently described PCR-select methodology. Using this technique, a kidney-specific mini-gene library was generated and a number of kidney-specific genes that share significant homology to previously characterized kidney genes from rats and other species were isolated. These included three renal-specific transporters (an ADH water channel, the anion transporters RST and ROAT1), a cell adhesion molecule (K-cadherin) and a kidney-specific protein upregulated in renal carcinoma (DD96). In addition, we isolated two novel genes from a rat kidney. One of the genes shares limited homology to rat profilin-1 while the other did not share any similarity to genes in the Genbank. Northern blot analysis revealed that the mRNA for each of these genes is expressed in a highly kidney-restricted fashion. Our results suggested that tissue-specific genes can be rapidly isolated and characterized using PCR-select techniques and this methodology may be generally applicable to isolate specific genes from a variety of tissues.

The number of alternatives to animal tests (non-animal test methods) for human health developed globally account for more than 40% of the test methods in the Organisation for Economic Co-operation and Development (OECD) Guidelines for the Testing of Chemicals (TGs). Within the TGs, the National Institute of Health Sciences (NIHS) has standardized 16 OECD TGs for human health, implemented four major revisions, and developed one test method for the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) S10 guidelines on photosafety. This review describes trends in the OECD and Japan that mainly focus on international standardizations of non-animal test methods for human health.

Background: Carotid atherosclerotic plaque is the primary cause of cardiovascular and cerebrovascular diseases. It is closely related to oxidative stress and immune inflammation. This bioinformatic study was conducted to identify key oxidative stress-related genes and key immune cell infiltration involved in the formation, progression, and stabilization of plaques and investigate the relationship between them.

Background: Closed head injury (CHI) provokes a prominent neuroinflammation that may lead to long-term health consequences. Microglia plays pivotal and complex roles in neuroinflammation-mediated neuronal insult and repair following CHI. We previously reported that induced neural stem cells (iNSCs) can block the effects of CXCL12/CXCR4 signaling on NF-κB activation in activated microglia by CXCR4 overexpression.

Rheumatoid arthritis (RA), a chronic inflammatory joint disease causing permanent disability, involves exosomes, nanosized mammalian extracellular particles. Circular RNA (circRNA) serves as a biomarker in RA blood samples. This research screened differentially expressed circRNAs in RA patient plasma exosomes for novel diagnostic biomarkers.

Background: Colorectal cancer (CRC) has high incidence and mortality rates, with severe prognoses during invasion and metastasis stages. Despite advancements in diagnostic and therapeutic technologies, the impact of the tumour microenvironment, particularly extracellular matrix (ECM) stiffness, on CRC progression and metastasis is not fully understood.
Methods: This study included 107 CRC patients.
