Postbiotics Enhance NK Cell Activation in Stress-Induced Mice through Gut Microbiome Regulation.

Recent studies have revealed that probiotics and their metabolites are present under various conditions; however, the role of probiotic metabolites (, postbiotics in pathological states) is controversial. Natural killer (NK) cells play a key role in innate and adaptive immunity. In this study, we examined NK cell activation influenced by a postbiotics mixture in response to gut microbiome modulation in stress-induced mice.

Prognostic Relevance of HJURP Expression in Patients with Surgically Resected Colorectal Cancer.

HJURP is a key factor for CENP-A deposition and maintenance in centromeres. The role of mis-regulation of histone chaperones in cancer initiation and progression has been studied. However, its role in colorectal cancer is still unclear.

Downregulation of miR-9 correlates with poor prognosis in colorectal cancer.

Introduction: microRNAs (miRNAs) are frequently dysregulated in many human cancers including colorectal cancer (CRC) and are useful candidate biomarkers in liquid biopsy of cancer for their stability in the blood.

Methods: We compared the expression of microRNA-9 (miR-9) in tissues (n = 357) and sera (n = 109) of CRC patients to determine whether miR-9 in serum reflects that in the cancer tissue in parallel. Also, we examined the miR-9 role in CRC by in vitro functional studies in four CRC cell lines.
