Promising new cancer therapy uses molecular 'Trash Man' to exploit a common cancer defense

While many scientists are trying to prevent the onset of a cancer defense mechanism known as autophagy, other researchers are leveraging it in a new therapy that causes the process to culminate in cell death rather than survival.

Authors: De Marinis F, Barberis M, Barbieri V, Marchianò A, Gasparini S, Migliorino MR, Romano G, Spinnato F, Vitiello F, Gridelli C Abstract INTRODUCTION: In the era of personalized cancer therapy, the sampling of adequate tumor tissue for histologic diagnosis and genomic profiling is crucial, not only at the initial diagnosis but also in the event of resistant and recurrent disease when sequential biopsies may be required to evaluate somatic mutations and histologic changes. Areas covered: The identification of genetic driver alterations led to the selection of patients who are most likely to benefit from ...

Publication date: Available online 14 January 2019Source: The Journal of Steroid Biochemistry and Molecular BiologyAuthor(s): Broes Martens, Zuzanna DrebertAbstractAngiogenesis is essential in tumor development to maintain the oxygen and nutrient supply. Glucocorticoids have shown both direct and indirect angiostatic properties in various types of solid cancers. In most of the reported cases glucocorticoid-mediated actions involved suppression of multiple pro-angiogenic factors expression by cancer cells. The anti-angiogenic properties of glucocorticoids correlated with diminished tumor vasculature and reduced tumor growth...

(University of California - San Francisco) In laboratory experiments, UC San Francisco researchers successfully beat back the growth of aggressive liver cancers using a surprising new approach. Traditionally, targeted cancer therapies aim to disable proteins borne of cancer-driving genes. Instead, the UCSF scientists prevented these proteins, including those that shield tumors from the immune system, from being built in the first place.

AbstractPurposeWe aimed to analyze the expression of ZWINT, NUSAP1, DLGAP5, and PRC1 in tumor tissues and adjacent tissues with public data.MethodsThe expression patterns of four genes were detected in cancer tissues and adjacent tissues by qRT-PCR. The overall survival analysis was used to explore these genes in lung adenocarcinoma and squamous cell carcinoma patients. Knockdown assays were used to select the most suitable gene among these four genes. Cell function assays with the knockdown gene were conducted in A549 and NCL H226 cells. The role of the knockdown gene in lung cancer was dissected in a mice tumor model. Tr...

Conclusions: Persistent fatigue at 1 year after EBRT in prostate cancer survivors is likely related to a cluster of symptoms elicited by chronic inflammation. Therapies that target each of these symptoms will likely reduce fatigue in this patient population.Oncology

Abstract Mechanistic target of rapamycin (mTOR) controls cell growth and metabolism in response to environmental and metabolic signals. Rapamycin robustly extends the lifespan in mammals and has clinical relevance in organ transplantation and cancer therapy but side effects include male infertility. Here, we report that chronic rapamycin treatment causes spermatogenic arrest in adult male mice due to defects in sex body formation and meiotic sex chromosome inactivation (MSCI). Many sex chromosome-linked genes were up-regulated in isolated pachytene spermatocytes from rapamycin-treated mice. RNA-Seq analysis also i...

In this study, we aimed to investigate the expression, biological function, and regulatory mechanism of miR-532-5p in bladder cancer. Herein, we found that miR-532-5p expression was frequently downregulated in bladder cancer tissues and cell lines compared with normal controls. Functional experiments showed that overexpression of miR-532-5p inhibited the proliferation and invasion of bladder cancer cells, whereas inhibition of miR-532-5p showed opposite effects. Interestingly, bioinformatics analysis predicted high-mobility group protein B3 (HMGB3) as a potential target gene of miR-532-5p. Further experiments showed that m...
