Cisplatin is one of the most widely used and effective chemotherapeutic agents for the treatment of several human malignancies. Although the effectiveness of cisplatin is high, its toxicities justify the demand for improved formulations of this drug. A liposomal formulation of cisplatin, Lipoplatin, was developed in order to reduce the systemic toxicity of cisplatin. Mice and rats injected with...

Cisplatin is one of the most widely used and highly effective drug for the treatment of various solid tumors; however, it has dose-dependent side effects on the kidney, cochlear, and nerves. Nephrotoxicity is the most well-known and clinically important toxicity. Numerous studies have demonstrated that several mechanisms, including oxidative stress, DNA damage, and inflammatory responses, are c...

Introduction: The principal dose-limiting factor in the use of cisplatin as an antineoplastic drug is its hepatic toxicity. This study was designed to investigate the protective role of taurine against cisplatin-induced hepatic injury. Methods: Male albino rats (180-220 g) were divided in to 4 groups (n=8) as follows: (1) saline-treated group (2): cisplatin-treated group (10 mg/kg ip) (3): g...

In the last years, many clinical studies have revealed that some cisplatin-treated cancer survivors have a significantly increased risk of cardiovascular events, being cisplatin-induced cardiovascular toxicity an increasing concern. The aim of the present work was to evaluate the cardiovascular alterations induced by different chronic cisplatin treatments, and to identify some of the mechanisms...

BACKGROUND A lymphatically delivered nanoconjugate of cisplatin was evaluated in an orthotopic mouse model of locoregionally metastatic breast cancer (LABC) to determine if it can overcome some of the limitations of standard cisplatin therapy such as high systemic toxicity. METHODS Human breast cancer cells (10(7) MDA-MB-468LN) were injected into the mammary fat pad of female nu/nu mice. Once...

Background While many of these agents have been compared in prospective clinical trials, the gemcitabine/platinumbased regimens have not been compared in a prospective, randomized clinical trial. While bothgemcitabine/carboplatin and gemcitabine/cisplatin have a similar ORR in separate clinical trials, the tworegimens have never been directly been compared. With overlapping dose-limiting toxici...

Cisplatin, a commonly used chemotherapeutic agent, is nephrotoxic. The mechanism by which cisplatin selectively kills the proximal tubule cells was heretofore unknown. Recent studies in mice and rats have shown that the nephrotoxicity of cisplatin can be blocked by acivicin or (aminooxy)acetic acid, the same enzyme inhibitors that block the metabolic activation of a series of nephrotoxic haloge...

Cisplatin is one of the most commonly used chemotherapeutic drugs; however, toxicity and tumor resistance limit its use. Studies using murine models and human subjects have shown that the time of day of cisplatin treatment influences renal and blood toxicities. We hypothesized that the mechanisms responsible for these outcomes are driven by the circadian clock. We conducted experiments using wi...

Cisplatin is a widely prescribed anticancer drug, which triggers cell death by covalent binding to a broad range of biological molecules. Among cisplatin targets, cellular RNAs remain the most poorly characterized molecules. Although cisplatin was shown to inactivate essential RNAs, including ribosomal, spliceosomal and telomeric RNAs, cisplatin binding sites in most RNA molecules are unknown, ...

During cancer chemotherapy toxicity to normal tissues often limits the tolerable dose. To increase drug delivery to tumor while maintaining tolerable systemic exposure, regional treatments, such as intraarterial drug delivery, have been used. Despite intraarterial delivery, systemic toxicity often remains the dose-limiting sensitivity. If systemic drug exposure could be reduced after intraarter...
