Special Issue Information

Dear Colleagues,

Inflammation is shown to be a risk factor of tumor development. Inflammation is characterized by the release of numerous pro-inflammatory cytokines, growth factors, increased blood vessel permeability and the migration of leukocytes. Among cytokines, IL-1β and IL-18, products of inflammasome, are the leading mediators of inflammation. Inflammasomes are the multiprotein complexes formed when pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patters (DAMPs) are present. Inflammasomes could be activated by multiple endogenous and exogenous stimuli, such as potassium ions efflux, reactive oxygen species, viruses, bacterial toxins, etc. The active inflammasome cleaves the pro-caspase 1 to release caspase 1, a proteolytic enzyme. Caspase 1 subsequently cleaves pro-IL-1β and pro-IL-18; therefore, the active forms of these cytokines are produced.

By releasing pro-inflammatory cytokines, inflammasomes could contribute to the initiation and maintenance of local inflammation. This inflammatory milieu could support cell proliferation, alter transcriptional activity and promote angiogenesis. Therefore, the regulation of inflammasome activity could be a novel approach for cancer treatment. We invite authors to submit the original research papers, case reports, and review articles with the following potential list of topics:

  1. The molecular regulation of inflammasome activation;
  2. The role of inflammasomes in cancer pathogenesis;
  3. Molecular mechanisms of novel therapeutic approaches for cancer treatment targeting inflammasomes;
  4. The mechanistic manipulation of inflammasome activity that aims to treat cancer and other diseases;
  5. Role of PAMPS, DAMPS and PRRs in immune responses to cancer.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

NOD-like receptor protein 3 (NLRP3) may contribute to the growth and propagation of breast cancer (BC). The effect of estrogen receptor-α (ER-α), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) on NLRP3 activation in BC remains unknown. Additionally, our knowledge of the effect of blocking these receptors on NLRP3 expression is limited. We used GEPIA, UALCAN, and the Human Protein Atlas for transcriptomic profiling of NLRP3 in BC. Lipopolysaccharide (LPS) and adenosine 5′-triphosphate (ATP) were used to activate NLRP3 in luminal A MCF-7 and in TNBC MDA-MB-231 and HCC1806 cells. Tamoxifen (Tx), mifepristone (mife), and trastuzumab (Tmab) were used to block ER-α, PR, and HER2, respectively, on inflammasome activation in LPS-primed MCF7 cells. The transcript level of NLRP3 was correlated with ER-ɑ encoding gene ESR1 in luminal A (ER-α+, PR+) and TNBC tumors. NLRP3 protein expression was higher in untreated and LPS/ATP-treated MDA-MB-231 cells than in MCF7 cells. LPS/ATP-mediated NLRP3 activation reduced cell proliferation and recovery of wound healing in both BC cell lines. LPS/ATP treatment prevented spheroid formation in MDA-MB-231 cells but did not affect MCF7. HGF, IL-3, IL-8, M-CSF, MCP-1, and SCGF-b cytokines were secreted in both MDA-MB-231 and MCF7 cells in response to LPS/ATP treatment. Tx (ER-α inhibition) promoted NLRP3 activation and increased migration and sphere formation after LPS treatment of MCF7 cells. Tx-mediated activation of NLRP3 was associated with increased secretion of IL-8 and SCGF-b compared to LPS-only-treated MCF7 cells. In contrast, Tmab (Her2 inhibition) had a limited effect on NLRP3 activation in LPS-treated MCF7 cells. Mife (PR inhibition) opposed NLRP3 activation in LPS-primed MCF7 cells. We have found that Tx increased the expression of NLRP3 in LPS-primed MCF7. These data suggest a link between blocking ER-α and activation of NLRP3, which was associated with increased aggressiveness of the ER-α+ BC cells. Full article
