Prospective cohort studies are needed to assess the relationship between fecal microbiome and human health disease. To evaluate collection methods, we determined technical reproducibility, stability at ambient temperature, accuracy of 5 methods (no additive, 95% ethanol, RNAlater Stabilization Solution, occult blood test cards, immunochemical tubes). Fifty-two healthy volunteers provided samples Mayo Clinic in Rochester, Minnesota, 2014. One set from each sample method was frozen...

Background: Lung cancer has the highest incidence and mortality rate of any worldwide. Platinum-based combination chemotherapy is still standard treatment for advanced lung cancer. However, clinical efficacy this can be affected by its adverse reactions, especially gastrointestinal mucositis. The reactions often lead to delayed reduced medication. role played gut microbiome in becoming clearer, evidence suggests that regulation may affect response multiple types treatment. Methods: Sixty...

Dysregulation of miRNAs in chondrocytes has been confirmed to participate osteoarthritis (OA) progression. Previous study screen out several key may play crucial role OA based on bioinformatic analysis. Herein, we identified the downregulation miR-1 samples and inflamed chondrocytes. The further experiments revealed that played an essential maintaining proliferation, migration, antiapoptosis, anabolism. Connexin 43 (CX43) was predicted be target miR-1, mediated promotion effects regulating...

Abstract Background Circulating tumor DNA (ctDNA) has potential as a specific, noninvasive, and cost‐effective new biomarker for patients with lung cancer. This study aimed to determine whether plasma ctDNA can be used predict treatment outcomes in Methods Pre‐ in‐treatment blood samples were collected from 14 cancer receiving chemotherapy. Based on next‐generation sequencing technology, we constructed unique molecular identifier (UMI) library performed targeted deep of 72 genes (15 000×)....

Abstract Introduction Targeted therapies are based on specific gene alterations. Various specimen types have been used to determine alterations, however, no systemic comparisons yet made. Herein, we assessed alterations in selected cancer‐associated genes across varying sample sites lung cancer patients. Materials and Methods deep sequencing for 48 tumor‐related was applied 153 samples from 55 patients obtained six sources: Formalin‐fixed paraffin‐embedded (FFPE) tumor tissues, pleural...

ABSTRACT Lung cancer is the leading cause of death. Better understanding factors and pathways involved in lung needed to improve diagnose treatment strategies. Recent studies have provided insights into possible correlation between intestinal dysbiosis development. Although immunological relationship gut had been suggested by many researches, however, date, no study investigated characterization microbiome naïve patients, whether it distinct from that health individuals contribute onset...

Klebsiella pneumoniae, an opportunistic pathogen, is pervasively distributed across the world. Its escalating antibiotic resistance poses a serious threat to global public health. The mechanisms behind this remain largely elusive. In study, we performed susceptibility testing on several clinical isolates of and reference strain ATCC13883, then analysed their transcriptomic profiles identify genes pathways associated with resistance. Our results showed that isolate DY16KPN may counteract...

FOXD2 Adjacent Opposite Strand RNA 1 (FOXD2-AS1), a long noncoding (lncRNA), exhibits specifically elevated in numerous cancerous cells. Numerous studies have shown that FOXD2-AS1 encourages cellular proliferation, migration and invasion. Nevertheless, the exact mechanism through which contributes to prostate cancer (PCa) remains unclear. Consequently, we aimed explore implications of on growth PCa. Initially, an elevation observed PCa cells (PC-3, DU145 Lncap) than normal cell line RWPE2....
