Tumour necrosis factor alpha-induced protein 2 (TNFAIP2) is a gene induced by tumor necrosis factor in endothelial cells. TNFAIP2 has important functions in physiological and pathological processes, including cell proliferation, adhesion, migration, angiogenesis, inflammation, tunneling nanotube (TNT) formation and tumorigenesis. Moreover, TNFAIP2 is the key factor in the formation of TNTs. TNTs are related to signal transduction between different cell types and are considered a novel means of cell-to-cell communication. Mesenchymal stem cells (MSCs) are pluripotent cells that exhibit self-renewal, multidirectional differentiation, paracrine function and immune-regulating ability. MSCs can transfer mitochondria through TNTs to improve the functions of target cells. This review revealed that TNFAIP2 promotes the formation of TNTs and that MSCs rely on TNTs for mitochondrial transfer to ameliorate cell dysfunction.

Recent research has shown that mtDNA-deficient cancer cells (ρ cells) acquire mitochondria from tumor stromal cells to restore respiration, facilitating tumor formation. We investigated the role of Miro1, an adaptor protein involved in movement of mitochondria along microtubules, in this phenomenon. Inducible Miro1 knockout (Miro1) mice markedly delayed tumor formation after grafting ρ cancer cells.

Transfer RNA-derived small RNAs (tsRNAs), a recently identified non-coding RNA subset, are mainly classified into tRNA-derived small RNA fragments (tRFs) and tRNA-derived stress-induced RNAs (tiRNAs). tsRNAs dysregulation is frequently observed in numerous cancer types, suggesting involvement in tumorigenesis. However, their functions in breast cancer (BC) remain to be fully understood.

Article Synopsis
- The transmembrane potential is crucial for cellular functions like signaling and energy production, with Rhodamine voltage reporters (RhoVRs) serving as small, non-invasive sensors that can detect voltage changes, especially in mitochondria.
- Extensive simulations and free-energy calculations revealed that the orientation of RhoVRs relative to membranes, influenced by their polarized functional groups, significantly impacts their voltage sensitivity and localization within cells.
- The study's findings on the relationship between the chemical structure of RhoVRs and their membrane behavior offer valuable insights for designing fluorescent dyes that better detect voltage changes.

Background: Populus tomentosa, known as Chinese white poplar, is indigenous and distributed across large areas of China, where it plays multiple important roles in forestry, agriculture, conservation, and urban horticulture. However, limited accessibility to the mitochondrial (mt) genome of P. tomentosa impedes phylogenetic and population genetic analyses and restricts functional gene research in Salicaceae family.
