• Resumen

  • Background Neurotransmitters released from the sympathetic nervous system attach to the adrenergic receptors on the surface of tumoral cells in response to stress, and alter the expression of genes programming cellular activity. This study aimed to assess the expression of α1 adrenergic receptors in the serum and saliva of patients with oral squamous cell carcinoma (OSCC) compared with healthy controls.

    Materials and methods In this case–control study, serum and stimulated and unstimulated saliva samples were collected from 26 OSCC patients and 26 healthy controls. ELISA kits were used for measurement of the serum and salivary levels of α1 adrenergic receptors.

    Results The level of α1 adrenergic receptors was signifcantly higher in the stimulated and unstimulated saliva of OSCC patients than healthy controls (P=0.000). However, their serum level was not signifcantly diferent between the two groups (P=0.389). The serum level of α1 adrenergic receptors signifcantly increased by an increase in OSCC grade. No signifcant correlation was noted between the serum and salivary levels of α1 adrenergic receptors in OSCC patients. The salivary level of α1 adrenergic receptors was signifcantly higher in patients with tumors located in the gingiva, compared with other sites.

    Conclusion Signifcantly higher salivary level of α1 adrenergic receptors in OSCC patients compared with healthy controls, and no signifcant diference in their serum level between the two groups may indirectly indicate the over-expression of these receptors in OSCC cells, compared with normal oral mucosa. Further studies and particularly histological analyses are required to confrm this fnding
