There is an overwhelmingly increasing trend of analysis of naturally occurring ingredients in treatment of prostate cancer. Substantial fraction of information has been added that highlights activity at various levels and steps of deregulated cellular proliferation, metastasis and apoptosis. Among such ingredients, algae extracts and jasmonates are documented to have anti-cancer activity in vitro and in vivo and induce growth inhibition in cancer cells, while leaving the non-transformed cells intact. In this short review we outline systematically, how these ingredients predispose prostate cancer cells to undergo apoptosis. © 2012 Farooqi et al.; licensee BioMed Central Ltd. Source

TRAIL mediated signaling in cancer cells has emerged as one amongst the most deeply studied molecular phenomenon. Data obtained through genetic studies has highlighted highly polymorphic nature of DR4 and in accordance with this concept, we aimed to investigate the association between Colorectal cancer and polymorphisms in TRAIL and DR4 gene. We selected 100 patients with colorectal cancer and 100 healthy, sex and age matched volunteers randomly. C626G and A1322G in DR4 gene were analyzed using Polymerase Change Reaction (PCR)-Restriction Fragment Length Polymorphism (RFLP) and Amplification Refractory Mutation System (ARMS) techniques. PCR-RFLP was used to study TRAIL 1595 C>T. TRAIL gene 1595 C>T genotypes percentage in colorectal cancer patients was statistically non-significant. CC was 43% in patients and 50% in controls. CT was 45% in patients and 43% in controls. TT was 12% in patients and 7% in controls. C allele was 0.655% in cancer patients and 0.715% in controls. T allele was 0.345% in patients and 0.285% in controls. DR4 gene 626 C>G genotypes percentage analysis indicated that CC was 28% in patients and 2% in controls. GC was 42% in patients and 40% in controls. GG was 30% in patients and 58% in controls. CC was statistically significant (p=0.00000207) in cancer patients. C allele was 0.49% in patients and 0.22% in controls. G allele was 0.51% in patients and 0.78% in controls. For DR4 A1322G, homozygous GG genotype was 36% in the patients and in controls. There was statistically insignificant difference (p> 0.05). The heterozygous GT genotype was 30% in patients and 29% in controls. This difference was statistically insignificant (p value > 0.05). Similarly, the homozygous genotype TT of the minor allele was (35%) in controls and patients (34 %). This difference was also statistically insignificant (p value > 0.05). C allele was 0.51% in patients and 0.5% in controls. T allele was 0.49% in patients and 0.495% in controls. Future studies must converge on a larger sample size, sporadic mutations of DR4 and TRAIL and expression profiling. © 2015. Source

Disruption of spatiotemporal behavior of intracellular signaling cascades including tumor necrosis factor alpha-related apoptosis-inducing ligand (TRAIL)-mediated signaling in prostate cancer has gained tremendous attention in the past few years. There is an increasing effort in translating the emerging information about TRAIL-mediated signaling obtained through experimental and preclinical data to clinic. Fascinatingly, novel targeting approaches are being developed to enhance the tissue- or subcellular-specific delivery of drugs with considerable focus on prostate cancer. These applications have the potential to revolutionize prostate cancer therapeutic strategies and include the accumulation of drugs in target tissue as well as the selection of internalizing ligands for enhanced receptor-mediated uptake of drugs. In this mini-review, we outline outstanding developments in therapeutic strategies based on the regulation and/or targeting of TRAIL pathway for the treatment of prostate cancer. Moreover, microRNAs (miRNAs), with potential transcriptional and posttranscriptional regulation of gene expression, will be presented for their potential in prostate cancer treatment. Emphasis has been given to the use of delivery approaches, especially based on nanotechnology. Considerably, enhanced information regarding miRNA regulation of TRAIL-mediated signaling in prostate cancer cells may provide potential biomarkers for the characterization of patients as responders and nonresponders of TRAIL-based therapy and could provide rationalized basis for combination therapies with TRAIL death receptor-targeting drugs. © 2013 Springer-Verlag Berlin Heidelberg.

There is increasing progress in translational oncology and tremendous breakthroughs have been made as evidenced by preclinical and clinical trials. Data obtained from high-throughput technologies are deepening our understanding about the molecular and gene network in cancer cells and rapidly emerging in vitro and in vivo evidence is highlighting the role of antisense agents as specific inhibitors of the expression of target genes, thus modulating the response of cancer cells to different therapeutic strategies. Much information is continuously being added into various facets of molecular oncology and it is now understood that over expression of antiapoptotic proteins, oncogenes, oncogenic microRNAs (miRNA), and fusion proteins make cancer cells difficult to target. Delivery of antisense oligonucleotides has remained a challenge and technological developments have helped in overcoming hurdles by improving the ability to penetrate cells, effective and targeted binding to gene sequences, and down regulation of target gene function. Different delivery systems, including stable nucleic acid lipid particles, have shown potential in enhancing the delivery of cargo to the target site. In this review, we attempt to summarize the current progress in the development of antisense therapeutics and their potential in medical research. We partition this multi component review into introductory aspects about recent breakthroughs in antisense therapeutics. We also discuss how antisense therapeutics have shown potential in resensitizing resistant cancer cells to apoptosis by targeted inhibition of antiapoptotic proteins, oncogenic miRNAs, and BCR-ABL. © 2014 Farooqi et al.

Objective: To evaluate the effect of intracameral dexamethasone on corneal endothelium. Study Design: Quasi experimental study. Place and Duration of Study: Layton Rehmatulla Benevolent Trust Eye Hospital, Lahore, from May 2011 to January 2012. Methodology: Study subjects were adults of either gender with senile cataract who underwent phacoemulsification. They were divided in two groups, each had 110 patients. Group-A received subconjunctival injection of dexamethasone (2 mg/0.5 ml) at the end of surgery while group-B received intracameral injection of dexamethasone (0.4 mg/0.1 ml) at the end of surgery. Endothelial cell count was performed by specular microscopy pre-operatively and postoperatively at first week, first month and three months. Outcome measures included changes in endothelial cell count. Results were compared using t-test for means. Results: There were 55 (50%) males and 55 (50%) females in group-A and 44 (40%) males and 66 (60%) females in group-B. In group-A, there were 66 (60%) right and 44 (40%) left eyes while group-B had 62 (56.36%) right and 48 (43.63%) left eyes. Mean age in group-A was 55.17 ± 5.93 years and 54.87 ± 5.55 years in group-B. Mean phacoemulsification time in group-A was 1.92 ± 0.63 minutes and 1.82 ± 0.54 minutes in group-B. After 3 months, in group-A, there was 7.55 ± 1.19% endothelial cell loss while in group-B, there was 7.63 ± 1.10% endothelial cell loss. The difference between the two groups was not statistically significant (p=0.614). Conclusion: Use of intracameral dexamethasone at the end of cataract surgery is safe for corneal endothelium.
