Genomic and transcriptomic signatures of sequential carcinogenesis from papillary neoplasm to biliary tract cancer.

Background & Aims: Papillary neoplasms of the biliary tree, including intraductal papillary neoplasms (IPN) and intracholecystic papillary neoplasms (ICPN), are recognized as precancerous lesions. However, the genetic characteristics underlying sequential carcinogenesis remain unclear.

Methods: Whole-exome sequencing was performed on 166 neoplasms (33 intrahepatic IPNs, 44 extrahepatic IPNs, and 89 ICPNs), and 41 associated carcinomas.

Optimization of FRET imaging in Arabidopsis Protoplasts.

Recent advancements in fluorescence-based biosensor technologies have enabled more precise and accurate Förster Resonance Energy Transfer (FRET) imaging within Agrobacterium-mediated plant transformation systems. However, the application of FRET imaging in plant tissues remains hindered by significant challenges, particularly the time-intensive process of generating transgenic lines and the complications arising from tissue autofluorescence. In contrast, protoplast-based FRET imaging offers a rapid and efficient platform for functional screening and analysis, making it an essential tool for plant research.

Limosilactobacillus reuteri fermented brown rice alleviates anxiety improves cognition and modulates gut microbiota in stressed mice.

Chronic stress disrupts gut microbiota homeostasis, contributing to anxiety and depression. This study explored the effects of Limosilactobacillus reuteri fermented brown rice (FBR) on anxiety using an ICR mouse chronic mild stress (CMS) model. Anxiety was assessed through body weight, corticosterone levels, neurotransmitter profiles, and behavioral tests.

Characteristics of successful expansion of tumor-infiltrating lymphocytes from colorectal cancer liver metastasis.

Adoptive cell therapy (ACT) utilizing tumor-infiltrating lymphocytes (TILs) has emerged as a successful treatment modality for various malignancies. However, TILs cultured from colorectal cancer (CRC) liver metastasis remain underexplored. Fifteen CRC liver metastasis tissues underwent initial expansion (IE) of TILs and rapid expansion (REP).
