Vincristine is one of the most common anticancer drugs clinically employed in the treatment of various malignancies. A major side effect associated with vincristine is the development of neuropathic pain, which is not readily relieved by available analgesics. Although efforts have been made to identify the pathogenesis of vincristine-induced neuropathic pain, the mechanisms underlying its patho...

The toxicity and antitumor activity of liposomal vincristine prepara tions have been examined. Vincristine was encapsulated inside egg phosphatidylcholine (EPC)/cholesterol (55/45, mol/mol) and distearoylphosphatidylcholine (DSPC)/cholesterol (55/45, mol/mol) vesicles utilizing transmembrane pH gradient (inside acidic) drug uptake processes. Trap ping efficiencies approaching 100% were achieved...

Background: Male factors, mainly spermatogenesis disorder, are responsible for 20-30% of infertility occurs in different societies. One of the known causes of spermatogenesis disorder is chemotherapy in patients with cancer. The side effect of chemotherapic agents may last from 10 years up to the end of the life. Since dividing cells are mainly affected by anticancer drugs, the aim of the prese...

Prolonged exposure to vincristine correlates with improved therapeutic activity. In this work, two methods are used to increase the circulation longevity of liposomal formulations of vincristine. The first involves incorporation of the ganglioside GM1, which acts to increase the circulation longevity of liposomal carriers, while the second approach relies on a modification of the vincristine en...

Clinical outcomes of vincristine therapy, both neurotoxicity and efficacy, are unpredictable, and the reported pharmacokinetics of vincristine have considerable interindividual variability. In vitro and in vivo data support a dominant role for CYP3A enzymes in the elimination of vincristine. Consequently, genetic polymorphisms in cytochrome P450 (P450) expression may contribute to the interindi...

Vincristine is an anticancer drug used to treat a variety of cancer types, but it frequently causes peripheral neuropathy. Neuropathic pain is often associated with the appearance of abnormal sensory signs, such as allodynia. Milnacipran and duloxetine, serotonin/noradrenaline reuptake inhibitors, have shown efficacy against several chronic pain syndromes. In this study, we investigated the att...

Vincristine is a microtubule-destabilizing antimitotic drug that has been used in cancer therapy for over 40 years. However, the knowledge on vincristine-induced cell death pathways is still sparse. Here, we show that vincristine induces dramatic changes in the lysosomal compartment and sensitizes cells to lysosomal membrane permeabilization. In HeLa cervix carcinoma cells, vincristine induced ...

In the Medical Research Council's lVth trial in Myelomatosis the possible benefit of adding vincristine to first line treatment with intermittent melphalan and prednisone has been assessed. This was analysed in 530 patients who were randomly allocated to receive vincristine or not. Survival was not improved by the addition of vincristine. A total of 268 patients reached plateau phase on first l...

Purpose: To determine the effect of targeted silencing CDX2 with siRNA on vincristine-induced inhibition proliferation and apoptosis induction in leukemia K562 cells.
 Methods: cells were divided into untreated group, vincristine blank CDX2-siRNA group. The expression gene after transfection was determined by reverse-transcription-polymerase chain reaction (RT-PCR) immunoblotting, while MT...
