Article Abstract
Background: This study aims to investigate the expression pattern and clinical significance of Piezo1 and Piezo2 in various cancers, focusing on gastric cancer (GC).
Methods: The study investigated the mRNA expression levels of Piezo1 and Piezo2 in tumor samples from different cancers using the BEST online database. The case-control studies about the relation between Piezo1 and Piezo2 and GC were retrieved from PubMed, Embase, Web of Science, and Cochrane Library. The retrieval time was from inception to October, 2023. The meta-analysis of the included literatures was conducted by the STATA 12.0 software. Additionally, the expression profiles of Piezo1 and Piezo2 in tumor and normal gastric tissues were analyzed, and their clinical drug relevance was assessed using the CPADS database. The research program has been registered with PROSPERO (CRD42023495836).
Results: The analysis demonstrated elevated mRNA expression of both Piezo1 and Piezo2 in the majority of tumor samples. Of particular note was the significant increase observed in GC tissue compared to normal tissue (all p < 0.05). Additionally, the meta-analysis revealed a meaningful correlation between high expression levels of Piezo1 and Piezo2 and poor prognosis in patients with GC (HR = 1.48, 95% CI = 1.27-1.69, p < 0.0001). This study identified a significant correlation between high levels of Piezo1 expression and the TNM phase (OR = 1.87, 95% CI = 1.21-2.91, p = 0.005). Furthermore, enhanced Piezo2 expression was observed to be positively correlated with survival status (OR = 2.12, 95% CI = 1.31-3.44, p = 0.002). Piezo1 (p = 0.028, R = 0.12) and Piezo2 (p = 0.049, R = 0.09) have been identified as potential therapeutic targets for GC treatment, according to drug sensitivity analyses.
Conclusion: The findings of this study indicate that the expression levels of Piezo1 and Piezo2 have the potential to serve as diagnostic indicators or therapeutic targets for GC management.
Trial Registration: CRD42023495836 (PROSPERO).

Enterochromaffin (EC) cell dysfunction decreases 5‑hydroxytryptamine (5‑HT) secretion, contributing to functional constipation (FC). However, the underlying mechanisms remain unclear. Piezo ion channels mediate 5‑HT release from EC cells.

Mechanotransduction is vital for sensing various mechanical stimuli, including blunt force and dynamic light touch. The sensation of a punctate mechanical force is very different from that of a brush swept across the skin, yet both involve mechanical stimulation of the skin and embedded sensory afferent endings. However, the sensory neuron mechanisms contributing to punctate vs light touch somatosensation, and how they might become dysregulated in nerve injury to cause pain, remain unclear.

The impact of allergic diseases on bone loss remains unclear because it is considered to result from the use of corticosteroids to ameliorate allergic inflammation. To explore the effects of allergic diseases on bone metabolism, we investigated long bones in ovalbumin (OVA)-induced asthmatic mice. Compared with that of vehicle-treated controls, the bone mass of OVA-induced asthmatic mice was lower.

Piezo channels are currently known to be the most sensitive molecular mechanoreceptors. Piezo can respond to membrane tension, sag, shear force, tensile and other mechanical stimuli, produces fast inactivation, small conductance, and low threshold current. In eukaryotic cells, Piezo has two family members: Piezo1 and Piezo2.

Mechanical forces shape immune responses in both health and disease. PIEZO1 and PIEZO2, two mechanosensitive ion channels, have emerged as critical transducers of these forces, influencing inflammation, pain, fibrosis, and neuroimmune regulation. This review aims to synthesize the current evidence on the role of PIEZO channels in mechano-inflammation, with a specific focus on their regulatory function in neuroimmune crosstalk.
