The development and progression of colorectal cancer (CRC) have been associated with genetic and epigenetic alterations and more recently with changes in cell metabolism. Amino acid transporters are key players in tumor development, and it is described that tumor cells upregulate some AA transporters in order to support the increased amino acid (AA) intake to sustain the tumor additional needs for tumor growth and proliferation through the activation of several signaling pathways. LAT1 and ASCT2 are two AA transporters involved in the regulation of the mTOR pathway that has been reported as upregulated in CRC. Some attempts have been made in order to develop therapeutic approaches to target these AA transporters, however none have reached the clinical setting so far. MiRNA-based therapies have been gaining increasing attention from pharmaceutical companies and now several miRNA-based drugs are currently in clinical trials with promising results. In this review we combine a bioinformatic approach with a literature review in order to identify a miRNA profile with the potential to target both LAT1 and ASCT2 with potential to be used as a therapeutic approach against CRC.

Background: The amino acid transporters alanine-serine-cysteine transporter 2 (ASCT2) and L-type amino acid transporter 1 (LAT1) are the primary transporters of essential amino acids in cancer. ASCT2 and LAT1 are overexpressed in solid tumors and have been associated with poor survival. These transporters may hold prognostic significance and offer potential theranostic utility in the treatment of glioma.

Purpose: Boron Neutron Capture Therapy (BNCT) has gained popularity in recent years, with over 500 treatment courses performed in Taiwan since 2017. Traditionally, the tumor-to-normal tissue ratio (T/N ratio) is assessed using SUV measurements from 4-borono-2-(18) F-fluoro-phenylalanine (F-BPA) PET, allowing for precise tumor boron concentration estimation when serum boron levels are measured on the day of treatment. However, limited accessibility to F-BPA PET complicates dose calculations, and in its absence, a fixed T/N ratio of 3 is used in treatment planning.

The cell membrane transport capacity and surface targets of multiple myeloma (MM) cells heavily influence chemotherapy and immunotherapy. Here, it is found that caveolin-1 (CAV1), a primary component of membrane lipid rafts and caveolae, is highly expressed in MM cells and is associated with MM progression and drug resistance. CAV1 knockdown decreases MM cell adhesion to stromal cells and attenuates cell adhesion-mediated drug resistance to bortezomib.

Ethnopharmacological Relevance: Scutellaria baicalensis Georgi, a widely used Chinese medicinal herb, has shown effectiveness against lung cancer. Scutellarein, a key component of Scutellaria baicalensis, also demonstrates anticancer properties in lung cancer. However, the underlying mechanisms have not yet been clarified.
