Effect of specific inhibitors of extracellular-signal regulated protein kinase (ERK) pathway, PD98059 and U0126, on P-glycoprotein (Pgp)-mediated vincristine resistance of L1210/VCR cells was investigated. Both test inhibitors significantly reduced the survival of L1210/VCR cells in the presence of vincristine and this was associated with a decrease of LC50 values to vincristine from 2.65+/-0.4...
Coadministration of azoles and vincristine has been shown to increase vincristine neurotoxic effects due to the inhibition of cytochrome P450 (CYP) isoform 3A4, for which vincristine is a substrate. Despite the absence of any casual relationship between seizure and coadministration of azoles, few case reports of vincristine-induced seizure have been documented after coadministration of fluconaz...
MAX8 β-hairpin peptide hydrogel is a solid, preformed gel that can be syringe injected due to shear-thinning properties and can recover solid gel properties immediately after injection. This behavior makes the hydrogel an excellent candidate as a local drug delivery vehicle. In this study, vincristine, a hydrophobic and commonly used chemotherapeutic, is encapsulated within MAX8 hydrogel and sh...
Vincristine is extensively used chemotherapeutic medicine to treat leukemia. However, it remains a critical clinical problem with regard to its toxicity and drug-resistance. AMP-activated protein kinase (AMPK) is an energy sensor that is pivotal in maintaining cell metabolic homeostasis. It is reported that AMPK is involved in vincristine-induced apoptosis. However, whether AMPK is involved in ...
A major obstacle to successful cancer chemotherapy is the dtvelopment of multidrug resistance (MDR) by tumor cells. Overexpression of the mdrl gene product I'-glycoprotein (P-170) is characteristic of such cells. In this study, in vitro and in vivo reversion of MDR was attempted in a human leukemia cell line resistant to vincristine (HL-60/Vinc) using an 18-mer mdrl antisense phosphorothioate o...

OBJECTIVES To evaluate the frequency and severity of occurrence of vincristine-associated neurotoxicity. DESIGN A retrospective case series study. SETTING Hurlingham Oncology Clinic, Nairobi. SUBJECTS Thirty-eight patients treated for various neoplasms with vincristine containing chemotherapeutic regimens. MAIN OUTCOME MEASURES The frequency and degree of neurotoxicity when vincristine ...
The incidence of vincristine-induced neuropathy was studied in 60 unselected patients, of whom 23 had lymphoma and 37 had other malignant disease. All were treated with vincristine combined with other cytotoxic agents. Fourteen of the patients with lymphoma (61%) developed neuropathy compared with five patients with leukaemia or non-lymphoid cancer (14%), even though all patients received compa...
