The biliary system plays an important role in several acquired and genetic disorders of the liver. We have previously shown that biliary duct epithelium contains cells giving rise to proliferative Lgr5+ organoids in vitro. However, it remained unknown whether all biliary cells or only a specific subset had this clonogenic activity. The cell surface protease ST14 was identified as a positive mar...

Colorectal cancer (CRC) was the second most commonly diagnosed worldwide and common cause of cancer-related deaths in Europe 2020. After CRC patients’ recovery, many cases a patient’s tumor returns develops chemoresistance, which has remained major challenge worldwide. We previously published our novel findings on role DA inhibiting activity GDH1 using silico enzymatic assays. No studies have b...

While radical cystectomy remains the primary treatment of choice for bladder cancer, increased evidence supports use bladder-preservation strategies based on adjuvant radiotherapy. This highlights need a better understanding cancer radiosensitivity to different types deliveries. The purpose this study is analyze effect time, dose and fractionation number sizes grown three-dimensional (3D) spher...

A clonogenic assay of long-term breast cancer cell cultures in vitro has been developed to provide a highly reproducible method with which to quantitate tumor cell killing by hormones and/or cytotoxic chemotherapeutic agents. Monolayer cultures of estrogen receptor-positive MCF-7 human breast cancer cells and of estrogen receptor-negative Evsa T cells are harvested by treatment with 0.01% tryps...

UNLABELLED Large collections of annotated cancer cell lines are powerful tools for precisely matching targeted drugs with genomic alterations that can be tested as biomarkers in the clinic. Whether these screening platforms, which utilize short-term cell survival to assess drug responses, can be applied to precision radiation medicine is not established. To this end, 32 cancer cell lines were s...

soybean isoflavone genistein has multiple anticancer properties and its pro-apoptotic and anti-proliferative effects have been studied in different cancer cells. however, the mechanisms of action of genistein and its molecular targets on human colon cells have not been fully elucidated. therefore, caspase-3 and p38 mitogen-activated protein kinase (p38 mapk) as the main therapeutic targets were...

This study reports the development of an assay, the Pre-colony-forming unit (CFU) assay, which detects human hematopoietic precursors. The Pre-CFU assay is based on the observation that precursors to CFU-granulocyte-macrophage (CFU-GM) that are undetectable in clonogenic assays differentiate into CFU-GM preferentially following treatment in suspension culture with recombinant human interleukin-...

The sensitivity of three different human and murine doxonibicin (Dx)sensitive or -resistant pairs of tumor cells to recombinant interleukin 2 (rii,2)-aclivaled lymphocytes was studied. In two pairs of these sublines (LoVo human colon carcinoma and B16 mouse melanoma sublines), resistance to Dx was induced in vitro, while in the third pair (9229 human metastatic melanoma clones), Dx resistance w...

The prostate secretory protein of 94 amino acids (PSP94) has been shown to interact with cysteine-rich secretory protein 3 (CRISP-3) in human seminal plasma. Interestingly, PSP94 expression is reduced or lost in the majority of the prostate tumours, whereas CRISP-3 expression is upregulated in prostate cancer compared with normal prostate tissue. To obtain a better understanding of the individu...
