Spatiotemporal analysis of F-actin polymerization with micropillar arrays reveals synchronization between adhesion sites.

We repurposed micropillar arrays to quantify spatiotemporal inter-adhesion communication. Following the observation that integrin adhesions formed around pillar tops we relied on the precise repetitive spatial control of the pillars to reliably monitor F-actin dynamics in mouse embryonic fibroblasts as a model for spatiotemporal adhesion-related intracellular signaling. Using correlation-based analyses, we revealed localized information flows propagating between adjacent pillars that were integrated over space and time to synchronize the adhesion dynamics within the entire cell.

The Role of Extracellular Vesicles in Cancer-Nerve Crosstalk of the Peripheral Nervous System.

Although the pathogenic operations of cancer-nerve crosstalk (e.g., neuritogenesis, neoneurogensis, and perineural invasion-PNI) in the peripheral nervous system (PNS) during tumorigenesis, as well as the progression of all cancer types is continuing to emerge as an area of unique scientific interest and study, extensive, wide-ranging, and multidisciplinary investigations still remain fragmented and unsystematic.

Perineural Invasion is a Better Prognostic Indicator than Lymphovascular Invasion and a Potential Adjuvant Therapy Indicator for pN0M0 Esophageal Squamous Cell Carcinoma.

Background: Esophageal squamous cell carcinoma (ESCC) at pN0M0 can be more locally aggressive and disseminated than those with lymph node and distant metastasis. Perineural invasion (PNI) is reported as a poor prognostic factor in cancer and is thought to be related to regional tumor spread and metastasis. However, its clinicopathological role and meaning for treatment in pN0M0 ESCC are unknown.

Microbiological evidences for gastric cardiac microflora dysbiosis inducing the progression of inflammation.

Background And Aim: Nowadays, anti-inflammation treatment is a promising approach for preventing tumorigenesis, and human microflora is closely related to inflammation. This study aimed to investigate the gastric cardiac microbiome and identify inflammation-related microorganisms for gastric cardiac inflammation.

Methods: We performed 16S rRNA sequencing on a total of 11 healthy individuals and 89 individuals with different degree of gastric cardiac inflammation.

Genetic Alterations in Esophageal Tissues From Squamous Dysplasia to Carcinoma.

Background & Aims: Esophageal squamous cell carcinoma (ESCC) is the most common subtype of esophageal cancer. Little is known about the genetic changes that occur in esophageal cells during the development of ESCC. We performed next-generation sequence analyses of esophageal nontumor, intraepithelial neoplasia (IEN), and ESCC tissues from the same patients to track genetic changes during tumor development.
