In the recent years, application of new antitumor drugs has focused on replacement conventional chemotherapeutics with compounds derived from natural products. Cannabidiol (CBD) is one 113 cannabinoids plant Cannabis sativa and characterized complex not entirely understood biological function. Unlike other most abundant cannabinoid in – tetrahydrocannabinol, cannabidiol low affinity to endocann...

More than 50% of human cancers contain p53 gene mutations and as a result accumulate altered forms of the full-length p53 protein. Although certain tumor types expressing mutant p53 protein have a poor prognostic process, the precise role of mutant p53 protein in highly malignant tumor cells is not well defined. Some p53 mutants, but not wild-type p53, are shown here to interact with Daxx, a Fa...

To enhance the penetration of P53 into tumor cells by fusion it with the cell penetrating peptide 9R. The fusion gene of 9R-p53 was cloned into the expression vector. The fusion protein, CPPs-P53, was expressed and purified. We detected the rate of cell growth inhibition and apoptosis by MTT and Annexin-V-FITC/PI double stained method respectively for measuring its effect on tumor cells. CPPs-P...

p73, the first p53 gene homologue, encodes an array of p73 proteins including p73 alpha full-length (TAp73 alpha) and amino-truncated isoforms (Delta Np73 alpha), two proteins with opposite biological functions. TAp73 alpha can induce tumor suppressive properties, while Delta Np73 alpha antagonizes p53 as well as TAp73 in a dominant-negative manner. In human malignant neuroblasts, p53 protein i...

The adoption of new treatment modalities remains crucial as lung cancer has one the lowest survival rates, along with liver and pancreatic cancer. Bortezomib is a proteasome inhibitor that higher anticancer effect in combination therapies. Therefore, aim this study to investigate whether bortezomib could have additional when combined cyclin-dependent kinase (CDK) inhibitor-roscovitine vitro. Ap...

Theoretical methods, such as molecular mechanics and dynamics, are very useful in understanding differences interactions at the single molecule level. In life sciences, small conformational changes, including substituent modifications, often have a significant impact on function vivo. Changes binding between nucleic acid molecules proteins prime example. this study, we propose strategy to predi...

Mutation in the p53 gene is arguably the most frequent type of gene-specific alterations in human cancers. Current p53-based gene therapy contains the administration of wt-p53 or the suppression of mutant p53 expression in p53-defective cancer cells. . We hypothesized that trans-splicing could be exploited as a tool for the correction of mutant p53 transcripts in p53-mutated human colorectal ca...

The majority of p53 mutations, which are responsible for gain of oncogenic function, are missense mutations in hotspot codons. However, in our previous study, we demonstrated that a deletion spanning codons 127-133 in the p53 gene (designated as del p53) was detected in doxorubicin-resistant MCF-7 cell lines following various induction processes. In the present study, we aimed to investigate th...

The effect of the antidiabetic drug metformin on tumor growth was investigated using the paired isogenic colon cancer cell lines HCT116 p53 and HCT116 p53 / . Treatment with metformin selectively suppressed the tumor growth of HCT116 p53 / xenografts. Following treatment with metformin, we detected increased apoptosis in p53 / tumor sections and an enhanced susceptibility of p53 / cells to unde...
