Background: Noncontact Electro Capacitive Cancer Therapy (ECCT) is a
novel treatment modality in cancer. Chemokine (C-C motif) ligand 2 (CCL2)
has a major role in the outgrowth of metastatic breast cancer. Interleukin 18
(IL18) plays a role in macrophage alteration, which leads to excessive
angiogenesis. This study aims to elaborate on the association of CCL2,
IL18, IL23?, and TNF-? (tumor necrosis factor-alpha) expression with the
anti-proliferative effect of ECCT in rat breast tumor tissue.
Methods: Low intensity (18 Vpp) and intermediate frequency (150 kHz)
alternating current-electric field (AC-EF) between two capacitive electrodes
were exposed as external EF to a rat cage. Twenty-four rats were divided
into four groups of six replicates. Breast tumor tissues were collected from
7, 12-dimethylbenz[a]anthracene (DMBA)-induced rats. Two groups were
none DMBA-induced rats without ECCT exposure (NINT) and with (NIT).
The other two groups were DMBA-induced rats without ECCT exposure
(INT) and with (IT). Mammary glands and breast tumor tissues were
collected from each group and preserved. Hematoxylin-eosin and
immunohistochemistry staining were performed on paraffin sections of
tissues using anti-PCNA, anti-ErbB2, anti-Caspase3, and anti-CD68. CCL2,
IL18, IL23?, and TNF-? mRNA relative expressions were analyzed using
qRT-PCR.
Results: ECCT exposure may cause the reduction of PCNA protein
expression as well as ErbB2 on breast tumor tissues, but it causes the
increase of Caspase3 and macrophage CD68 protein. In rat breast tumor tissues of IT groups, the mRNA expression of CCL2 and IL18 are
significantly down-regulated, in contrast with the up-regulated expression of
these cytokines in tumor tissues of the INT group. IL23? and TNF- ?
expression remained similar in both groups.
Conclusion: CCL2 and IL18 expressions have an association with the
inhibition of breast tumor cell proliferation affected by ECCT exposure
