HOXA1 promotes epithelial-mesenchymal transition and malignant characteristics of laryngeal squamous cell carcinoma.

Despite considerable advancements in the diagnosis and treatment of LSCC, there has been no significant improvement in survival rate. Consequently, identifying molecular targets for this cancer is of paramount importance. HOXA1, a constituent of the homeobox transcription factor cluster, plays a role in the development of various types of cancer. Nevertheless, the specific function and mechanism of HOXA1 in LSCC remains unclear. This study aimed to clarify the impact of HOXA1 on the advancement of LSCC and uncover its underlying mechanism. Our findings indicate that HOXA1 exhibits a significantly elevated expression level in LSCC. Suppression of HOXA1 inhibited the proliferation of LSCC cells. Furthermore, the ablation of HOXA1 triggered the apoptosis of LSCC cells and inhibited EMT. Functionally, HOXA1 has a role in initiating the activation of the PI3K/AKT/mTOR pathway in LSCC cells. In summary, HOXA1 significantly contributes to the EMT of LSCC cells via the PI3K/AKT/mTOR signaling pathway, thereby facilitating the proliferation and motility of LSCC cells. Consequently, HOXA1 presents itself as a viable therapeutic target for LSCC interventions.
