Traction-force microscopy (TFM) has emerged as a widely used standard methodology to measure cell-generated traction forces and determine their role in regulating cell behavior. While TFM platforms have enabled many discoveries, their implementation remains limited due to complex experimental procedures, specialized substrates, and the ill-posed inverse problem whereby low-magnitude high-frequency noise in the displacement field severely contaminates the resulting traction measurements. Here, we introduce deep morphology traction microscopy (DeepMorphoTM), a deep-learning alternative to conventional TFM approaches.

Epithelial-to-mesenchymal transition (EMT) plays a crucial role in metastasis, which is the leading cause of death in breast cancer patients. Here, we show that Cdc42 GTPase-activating protein (CdGAP) promotes tumor formation and metastasis to lungs in the HER2-positive (HER2) murine breast cancer model. CdGAP facilitates intravasation, extravasation, and growth at metastatic sites.

In mesenchymal cell motility, several migration patterns have been observed, including directional, exploratory and stationary. Two key members of the Rho-family of GTPases, Rac and Rho, along with an adaptor protein called paxillin, have been particularly implicated in the formation of such migration patterns and in regulating adhesion dynamics. Together, they form a key regulatory network that involves the mutual inhibition exerted by Rac and Rho on each other and the promotion of Rac activation by phosphorylated paxillin.

Article Synopsis
  • The human gut microbiota significantly influences metabolism, interacting closely with its host's genetics, diet, and lifestyle.
  • The composition of gut microbial communities provides additional metabolic functions and helps regulate hormonal and cellular signals for adapting to various changes.
  • Imbalances in these microbial communities, known as dysbiosis, can lead to metabolic diseases like obesity, diabetes, and atherosclerosis, as well as affecting outcomes from bariatric surgery and exercise.
