Gasdermins have been identified as playing a prominent role in the innate immune response as the executors of a specific type of cell death called pyroptosis. Specific proteolytic cleavage of gasdermins generates an N-terminal that oligomerizes and forms pores in the cell membrane. Although pyroptosis has been widely described in mammals, the importance of gasdermins and gasdermin-like proteins in inducing cell death in other vertebrates, in invertebrates and in other taxa including fungi and bacteria is still being determined. Mammalian, fungal and bacterial gasdermins have in common the fact that they go through the same stages (such as proteolytic activation) when inducing membrane rupture, which suggests that pyroptosis is as an ancient mechanism. In this review, we summarize the evolution and function of the gasdermin and gasdermin-like proteins in animals, fungi and bacteria.

Background And Study Aims: Hirschsprung disease (HD) is a complex developmental disease that resulted from impaired proliferation and migration of neural crest cells. Despite the genetic causation of enteric nervous system have been found to be responsible for part of HD cases, the genetic aetiology of most HD patients still needs to be explored.
Patients And Methods: Whole-genome sequencing and subsequent Sanger sequencing validation analysis were performed in 13 HD children and their unaffected parents.

Aims: Hypertrophic cardiomyopathy (HCM) is characterized by unexplained left ventricular hypertrophy (LVH) with key pathologic processes including myocardial necrosis, fibrosis, inflammation, and hypertrophy, which are involved in heart failure (HF), stroke, and even sudden death. Our aim was to explore the communication network among various cells in the heart of transverse aortic constriction (TAC) surgery induced HCM mice.
Materials And Methods: Single-cell RNA-seq data of GSE137167 was downloaded from the Gene Expression Omnibus (GEO) database.

The uptake of Ca by mitochondria is an important and tightly controlled process in various tissues. Even small changes in the key proteins involved in this process can lead to significant cellular dysfunction and, ultimately, cell death. In this study, we used stimulated emission depletion (STED) microscopy and developed an unbiased approach to monitor the sub-mitochondrial distribution and dynamics of the mitochondrial calcium uniporter (MCU) and mitochondrial calcium uptake 1 (MICU1) under resting and stimulated conditions.

Tumors evolve through the acquisition of increasingly aggressive traits associated with dysplasia. This progression is accompanied by alterations in tumor mechanical properties, especially through extracellular matrix remodeling. However, the contribution of pre-tumoral tissue mechanics to tumor aggressiveness remains poorly known in vivo.

Background: The infiltration of tumor-infiltrating B cells and plasma cells in early-stage breast cancer has been associated with a reduced risk of distant metastasis. However, the influence of B-cell tumor infiltration on overall patient survival remains unclear.
Materials And Methods: This study explored the relationship between an antitumor immune response, measured by a 14-gene B-cell/immunoglobulin (IGG) signature, and mortality risk in 9638 breast cancer patients across three datasets.
