OBJECTIVES P In vitro chemosensitivity and resistance assays (CSRAs) are a promising tool for personalized treatment of glioblastoma multiform (GBM). These assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. We aimed to assess the feasibility and validity of utilizing stereotactic biopsies of GBM in CSRAs. MATERIALS AND METHODS Single ...

PURPOSE Despite initial sensitivity to chemotherapy, ovarian cancers (OVCA) often develop drug resistance, which limits patient survival. Using specimens and/or genomic data from 289 patients and a panel of cancer cell lines, we explored genome-wide expression changes that underlie the evolution of OVCA chemoresistance and characterized the BCL2 antagonist of cell death (BAD) apoptosis pathway ...

-The in vitro chemosensitivity of primary monolayer cultures of human ovarian tumours to a wide range of chemotherapeutic agents has been determined using 3H-leucine incorporation as an index of cytotoxicity. Of 67 specimens received, 35 have been successfully cultured and tested for chemosensitivity. Drugs tested included alkylating agents, antibiotics, antimitotics, antimetabolites and proges...

The use of [3H]thymidine incorporation assay (TIA) to evaluate the drug response of tumor cells has been recognized as a useful chemosensitivity assay for fresh human tumor specimens. However, its low evaluability has been a disadvantage for clinical application. To overcome this drawback, we have applied a preculture stage prior to the TIA. This preculture requires plating the tumor cell suspe...

Purpose: Despite initial sensitivity to chemotherapy, ovarian cancers (OVCA) often develop drug resistance, which limits patient survival.

Uterine cervical cancer is a leading cause of cancer-related death in the female population worldwide. In vitro chemosensitivity test is important to find effective drugs in uterine cervical cancer that requires the established chemotherapeutic strategies. The purpose of this study is to investigate the chemosensitivity of uterine cervical cancer using the histoculture drug response assay (HDRA...

BACKGROUND TRIM29 belongs to the tripartite motif (TRIM) protein family. It has been reported to be a tumor suppressor or have oncogenic function in many cancer types. The aim of this study was to investigate whether downregulation of TRIM29 by small interfering ribonucleic acid (siRNA) could inhibit cell proliferation and invasion and increase chemosensitivity to cisplatin in human lung squamo...

Purpose. Osteosarcoma is the most common primary bone tumor. Polypeptide N-acetylgalactosaminyltransferase 14 (GALNT14), a member of family, has been considered to be associated with various cancers. However, its role in osteosarcoma remains unknown. Here, we aimed explore expression and potential mechanism GALNT14 through bioinformatics analysis vitro experiments. Methods. We investigated usin...
