The implication of microbiome in lungs cancer: mechanisms and strategies of cancer growth, diagnosis and therapy.

Available evidence illustrates that microbiome is a promising target for the study of growth, diagnosis and therapy of various types of cancer. Lung cancer is a leading cause of cancer death worldwide. The relationship of microbiota and their products with diverse pathologic conditions has been getting large attention. The novel research suggests that the microbiome plays an important role in the growth and progression of lung cancer. The lung microbiome plays a crucial role in maintaining mucosal immunity and synchronizing the stability between tolerance and inflammation. Alteration in microbiome is identified as a critical player in the progression of lung cancer and negatively impacts the patient. Studies suggest that healthy microbiome is essential for effective therapy. Various clinical trials and research are focusing on enhancing the treatment efficacy by altering the microbiome. The regulation of microbiota will provide innovative and promising treatment strategies for the maintenance of host homeostasis and the prevention of lung cancer in lung cancer patients. In the current review article, we presented the latest progress about the involvement of microbiome in the growth and diagnosis of lung cancer. Furthermore, we also assessed the therapeutic status of the microbiome for the management and treatment of lung cancer.

Salmonella enterica subsp. enterica host-pathogen interactions and their implications in gallbladder cancer.

BACKGROUND: Several studies have linked chronic typhoid infection with gallbladder carcinoma without completely understood mechanism. This study was performed in order to understand role of Salmonella in gallbladder cancer etiology. METHODS: Known Salmonella host-pathogen interactions were screened from database in addition to known gallbladder carcinoma targets. Host-pathogen interaction map of S. enterica was prepared and screened for interactions with gallbladder carcinoma targets. Further functional overrepresentation analysis was performed to understand the role of human targets involved in Salmonella host-pathogen interactions in gallbladder carcinoma. RESULTS: Salmonella interact with several human proteins involved in gallbladder carcinoma. MAPK and RAC1 are the most important human proteins based on node degree value among all GBC associated interactors identified in current data search. Functional over-representation analysis reveals that Salmonella can induce adenocarcinoma which constitutes 85% of gallbladder cancer. CONCLUSION: Though, the role of MAPK/ERK and PI3K/AKT/mTOR pathway is already suggested for Salmonella mediated gallbladder cancer, but current data based approach indicate several new insight for exploration of the role of Salmonella in gallbladder cancer etiology. The results indicate about several other processes including CREB/SP-1 and BSG(CD147) signaling, that must be given consideration for understanding the role of Salmonella in gallbladder cancer.

Reconnoitring the impact of different extraction techniques on ginger bioactive moieties extraction, antioxidant characterization and physicochemical properties for their therapeutic effect.

The core directive of current study was to compare the different extraction techniques for their extraction yield of ginger bioactive moieties. Purposely, ultrasonic assisted and supercritical fluid extraction techniques were adapted alongside conventional solvent extraction for comparison. The variables targeted for the extraction process in different modules were time (20, 30, 40 minutes), temperature (30, 40, 50oC), solvent to sample ratio (4:6, 6:4, 8:2), pressure (2000, 3000, 4000 psi) and amplitude (20, 30, 40%). All variables were found to be momentously (P>0.05) effecting the extraction rates. The antioxidant potential of bioactive moieties was evaluated through FRAP, DPPH and ABTS. The outcomes of the optimization process suggested that the total phenolic content and total flavonoids content extracted through 80% ethanol at 50oC for 40 minutes showed maximum antioxidant activity. However, ultrasound assisted extraction, by using 80% ethanol, at 50oC for 40 minutes and at ultrasonic amplitude of 40% exhibited best results. Moreover, supercritical fluid extraction at 50oC for 40 minutes at5000 psi pressure, showed maximum extraction potential. All the extracts gathered through conventional, ultrasound and supercritical techniques were further quantified through HPLC protocols. The statistical interpretation of the results from all the analytical findings revealed highest concentration of polyphenols in supercritical fluids extracts followed by ultrasound and conventional extracts. One best treatment on the basis of superior nutritional profile as depicted by HPLC quantification was selected for the formulation of ginger drink. Physicochemical analysis elucidated momentous upshot on color, pH and acidity with progressive storage period whereas TSS followed a non-significant trend. Moreover, storage interval and treatments significantly affected the antioxidant potential of drinks.
