Serum starvation enhances nonsense mutation readthrough
AbstractOf all genetic mutations causing human disease, premature termination codons (PTCs) that result from splicing defaults, insertions, deletions, and point mutations comprise around 30%. From these mutations, around 11% are a substitution of a single nucleotide that change a codon into a premature termination codon. These types of mutations affect several million patients suffering from a large variety of genetic diseases, ranging from relatively common inheritable cancer syndromes to muscular dystrophy or very rare neuro-metabolic disorders. Over the past three decades, genetic and biochemical studies have revealed that certain antibiotics and other synthetic molecules can act as nonsense mutation readthrough-inducing drugs. These compounds bind a specific site on the rRNA and, as a result, the stop codon is misread and an amino acid (that may or may not differ from the wild-type amino acid) is inserted and translation occurs through the premature termination codon. This strategy has great therapeutic potential. Unfortunately, many readthrough agents are toxic and cannot be administered over the extended period usually required for the chronic treatment of genetic diseases. Furthermore, readthrough compounds only restore protein production in very few disease models and the readthrough levels are usually low, typically achieving no more than 5% of normal protein expression. Efforts have been made over the years to overcome these obstacles so that readthrough treatment c...
ConclusionHigh levels of lifestyle-related cancer-risk behaviors were found in most of the Hong Kong construction workers studied. The present study contributes to understanding how cancer-related lifestyle risk behaviors cluster among construction workers and relative impact factors of risk behaviors. It is essential to tailor health behavior interventions focused on multiple risk behaviors among different groups for further enlarging the effects on cancer prevention.
We report one case, in which the patient presented to the emergency department with lower urinary tract symptoms, fever and consumptive syndrome. Acute prostatitis was initially suspected, but subsequently prostate adenocarcinoma was diagnosed.This case enables us to consider the possibility of prostate adenocarcinoma as the diagnose in patients with fever of unknown origin, and the role of procalcitonin to rule out the presence of infection.

CooperbergAbstractBackgroundActive surveillance (AS)/watchful waiting (WW) strategy for localized prostate cancer (PCa) is increasingly and broadly endorsed as a preferred option for initial treatment of men with very low- and low-risk PCa, but outcomes can be difficult to analyze in traditional, population-based registries. The recently released Surveillance, Epidemiology, and End Results (SEER) Prostate with WW dataset provides an op...
ConclusionsElderly patients had the same management as young patients, with no difference in surgery or survival, but with an increase in early loss of autonomy.

ConclusionIn this experimental model, combined therapy with chemotherapy and Adv-shPGK1 improves control of PM of gastric origin as compared to chemotherapy alone and might counteract chemoresistance of PM. A systemic toxicity of Adv-shPGK1 cannot be excluded.
