摘要:
Clostridium difficile disease involves a range of clinical presentations ranging from carrier status with other causes of symptoms to mild and self-limiting diarrhea to life-threatening pseudomembranous colitis and megacolon. Cases of C. difficile are treated differently depending on the presence and then the severity of disease. Patients that are carriers may not receive treatment with concern of causing the disease. Mild to moderate cases may be treated with metronidazole while severe and relapsing cases are often treated with vancomycin or fidaxomicin. Current molecular assays are highly sensitive for detecting toxigenic C. difficile and cannot rule out carrier status. Utilization of a biomarker panel that includes C. difficile antigen (GDH), toxins A and B, and fecal lactoferrin allows clinicians to differentiate between a carrier state and active state of C. difficile and allows for monitoring to evaluate the effectiveness of treatment.

Targeting metabolic enzymes in human cancer Abstract Lung cancer is a devastating disease and a major therapeutic burden with poor prognosis. The functional heterogeneity of lung cancer (different tumor formation ability in bulk of tumor) is highly related with clinical chemoresistance and relapse. Here we find that, glycine dehydrogenase (GLDC), one of the metabolic enzyme involved in glycine metabolism, is overexpressed in various subtypes of human lung cancer and possibly several other types of cancers. GLDC was found to be highly expressed in tumor-initiating subpopulation of human lung cancer cells compared with non-tumorigenic subpopulation. By array studies we showed that normal lung cells express low levels of GLDC compared to xenograft and primary tumor. Functional studies showed that RNAi inhibition of GLDC inhibits significantly the clonal growth of tumor-initiating cells in vitro and tumor formation in immunodeficient mice. Overexpression of GLDC in non-tumorigenic subpopulation convert the cells to become tumorigenic. Furthermore, overexpression of GLDC in NIH/3T3 cells and human primary lung fibroblasts can transform these cells, displaying anchorage-independent growth in soft agar and tumor-forming in mice. Not only is GLDC is expressed human lung cancer, it is also up-regulated in other types of cancer, such as colon cancer. RNAi knockdown of GLDC in colon cancer cell line, CACO-2 cells, can also inhibit the tumor formation in mice. Thus GLDC maybe a new metabolic target for treatment of lung cancer, and other cancers.

In a first aspect, the present invention relates to a method for diagnosing or determining the status of tuberculosis infection in an individual afflicted with or suspected to be afflicted with tuberculosis infection. In a further aspect, a method for the stratification of the therapeutic regimen of an individual with tuberculosis infection is provided as well as a method for predicting a clinical outcome or determining treatment course in an individual afflicted with tuberculosis infection. Moreover, the present invention provides a method for monitoring the change from latent into active status of tuberculosis infection or vice versa in an individual. Furthermore, the present invention relates to a kit for use in diagnosing or detecting the status of tuberculosis infection as well as to Mycobacterium tuberculosis alanine dehydrogenase for use in specifically differentiating latent status from active diseases status of tuberculosis in an individual.
