Although sunitinib shows a high response rate in patients with untreated metastatic renal cell carcinoma (mRCC), quite a few patients show no therapeutic effect. Therefore, it is crucial to distinguish the patients who respond to sunitinib from those who do not as early as possible after the administration of the therapy. We herein report a case of mRCC in which (11)C-acetate (AC) positron emission tomography (PET) showed an early therapeutic effect of sunitinib treatment 4 weeks after its administration.

Protein kinase CK2 sustains de novo fatty acid synthesis by regulating the expression of SCD-1 in human renal cancer cells.
Cancer Cell Int
December 2024
Department of Biochemistry, Western University, London, ON, Canada.
Background: Clear cell renal cell carcinoma (ccRCC) is a type of cancer characterized by a vast intracellular accumulation of lipids that are critical to sustain growth and viability of the cells in the tumour microenvironment. Stearoyl-CoA 9-desaturase 1 (SCD-1) is an essential enzyme for the synthesis of monounsaturated fatty acids and consistently overexpressed in all stages of ccRCC growth.
Methods: Human clear cell renal cell carcinoma lines were treated with small-molecule inhibitors of protein kinase CK2.

Division of Pharmacotherapeutics, Department of Clinical Pharmacy, School of Pharmacy, Showa University, 1-5-8 Hatanodai, Shinagawa-ku, Tokyo, 142-8555, Japan.
Purpose: The blood concentrations of some tyrosine kinase inhibitors are known to decrease with long-term administration. We evaluated the variability in the serum concentrations of sunitinib and its metabolites in patients receiving long-term sunitinib treatment.
Methods: This study prospectively recruited patients who received sunitinib for metastatic renal cell carcinoma at the Showa University Hospital between March 2020 and January 2022.

Purpose: Renal cell carcinoma (RCC), exhibiting remarkable heterogeneity, can be highly infiltrated by regulatory T cells (Tregs). However, the relationship between Treg and the heterogeneity of RCC remains to be explored.
Methods: We acquired single-cell RNA-seq profiles and 537 bulk RNA-seq profiles of TCGA-KIRC cohort.

The current comprehensive study showcases a meticulous synthesis of novel class of α-benzilmonoxime thiocarbohydrazide (BMOTC) derivatives, and manifesting their multifaceted potential as antibacterial, antifungal, and anticancer agents. The synthesis of target compounds was performed in three phases using literature methods. In the first step, benzilmonoxime is synthesized using benzil and hydroxyl amine hydrochloride, followed by benzilmonoxime imine using thiocarbohydrazide.
