LL-37 Might Promote Local Invasion of Melanoma by Activating Melanoma Cells and Tumor-Associated Macrophages. Cancers (Basel) 2023; 15:cancers15061678. [PMID: 36980564 PMCID: PMC10046113 DOI: 10.3390/cancers15061678] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/17/2023] [Accepted: 03/06/2023] [Indexed: 03/12/2023] Open
Abstract
LL-37 can stimulate various skin-resident cells to contribute to tumor development. Since tumor (T) stage is determined by the vertical invasion of tumor cells in melanoma, we hypothesized that the LL-37 expression level is correlated with the T stage in melanoma patients. Immunohistochemical staining of LL-37 was performed in each stage of melanoma (Tis-T4), suggesting the ratio of LL-37-expressing cells correlate positively to T stage severity. Next, to examine pro-angiogenetic factors induced by LL-37 stimulation, the B16F10 melanoma model was used. Intra-tumorally administered CRAMP, the mouse ortologe of LL-37, significantly increased the mRNA expression of CXCL5, IL23A, MMP1a, and MMP9 in B16F10 melanoma. To confirm the induction of pro-angiogenic factors, A375 human melanoma cells were stimulated by LL-37 in vitro. The mRNA expression of CXCL5, IL23A, and MMP9, but not MMP1, were significantly increased by LL-37 stimulation. Moreover, LL-37-stimulated A375 culture supernatant promoted tube networks, suggesting that these tumor-derived factors promote the pro-angiogenic effect on tumor development. In contrast to melanoma cell lines, M2 macrophages stimulated by LL-37 in vitro significantly increased their expression and secretion of MMP-1, but not MMP-9 expression. Collectively, these results suggest that LL-37 stimulates both tumor cells and macrophages to promote melanoma invasion by the induction of pro-angiogenic factors.

Abstract
Cancers are complex, heterogeneous, dynamic and aggressive diseases exhibiting a series of characteristic biophysical traits which complement the original biological hallmarks of cancers favouring progressive growth, metastasis, and contributing to immune evasion and treatment resistance. One of the prevalent differences between most solid tumors and their corresponding, healthy tissues is a significantly higher water content (hyperhydration) in cancers. As a consequence, cancers have distinctly higher (Fick's) diffusion coefficients D [cm2 s-1] for the respiratory gases O2 and CO2, the key substrate glucose, and for the oncometabolite lactate. In addition, cancers have (a) clearly increased specific heat capacities cp [J g-1 K-1], thus representing high-capacity-tissues upon therapeutic heating induced by electromagnetic irradiation, and (b) higher thermal conductivities k [W m-1 K-1], i.e., increased abilities to conduct heat. Therefore, in diffusion analyses (e.g., when describing critical O2 and glucose supplies or CO2 removal, and the development of hypoxic subvolumes) and for modeling temperature distributions in hyperthermia treatment planning, these specific cancer-related data must be considered in order to reliably reflect oncologic thermo-radiotherapy settings.

Exp Dermatol 2023; 32:50-59. [PMID: 36168721 DOI: 10.1111/exd.14681] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 09/20/2022] [Accepted: 09/23/2022] [Indexed: 01/12/2023]
Abstract
Plasminogen activating inhibitor-1 (PAI-1) is associated with poor clinical outcomes, and elevated levels of PAI-1 in both tissue and serum are correlated with poor response to therapy in various cancers, including skin cancer. Cutaneous angiosarcoma (CAS) is a vascular tumor histologically characterized by detachment of endothelial cell-derived tumor cells. Since CAS expresses multiple angiogenic growth factors and has increased expressions of angiogenic receptor tyrosine kinase transcripts including VEGFR1/2/3, angiogenesis-promoting factors are potential drug targets in CAS. In this study, the expression of PAI-1 was examined in 31 cases of CAS, and the immunomodulatory effects of PAI-1 on a human CAS cell line, ISO-HAS-B, were evaluated. We found that, of the angiogenesis-promoting factors, PAI-1 was expressed in almost all cases of CAS, and PAI-1 increased the mRNA expressions of IL-23p19, VEGF-C, CXCL5 and CCL20 on ISO-HAS-B. Moreover, PAI-1 stimulated ISO-HAS-B culture supernatant promoted favourable tube networks, suggesting that these tumor-derived factors promote the pro-angiogenic effect on tumor development. In addition, IL-23p19 was expressed in 61.3% of cases, whereas VEGF-C was expressed in 41% of cases. The results of the present study suggest that PAI-1 promotes angiogenesis that results in tumor progression in CAS.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is a fibrohistiocytic tumor characterized by a high risk of local recurrence but a low risk of metastasis. A small subpopulation of DFSP undergoes fibrosarcomatous (FS) change, and approximately 15%-57% of cases of DFSP with FS change metastasizes, leading to a poor prognosis. In this report, a case of metastatic FS-DFSP that was successfully treated with imatinib mesylate in which the IHC staining pattern of recurrent DFSP was quantitatively analyzed in primary and metastatic DFSP areas, is described. Importantly, the recurrent area was composed of two IHC staining patterns (CD34 low PD-L1 high Ki67 high and CD34 high PD-L1 low Ki67 low pattern, while the metastatic area showed a clonal pattern (CD34 high PD-L1 low Ki67 intermediate ) in the present case. In this report, we described a case of metastatic fibrosarcomatous DFSP successfully treated with imatinib mesylate. This case suggests a subpopulation of DFSP with a favorable metastatic pattern.

Abstract
Immune checkpoint inhibitors (ICIs), such as anti-programmed cell death 1 (PD1) antibodies (Abs) and anti-cytotoxic T-lymphocyte associated protein 4 (CTLA4) Abs, have been widely administered for not only advanced melanoma, but also various non-melanoma skin cancers. Since profiles of tumor-infiltrating leukocytes (TILs) play important roles in immunotherapy using ICIs, it is important to evaluate cancer stromal cells such as tumor-associated macrophages (TAMs) and cancer-associated fibroblasts (CAFs), as well as stromal extracellular matrix protein, to predict the efficacy of ICIs. This review article focuses particularly on TAMs and related factors. Among TILs, TAMs and their related factors could be the optimal biomarkers for immunotherapy such as anti-PD1 Ab therapy. According to the studies presented, TAM-targeting therapies for advanced melanoma and non-melanoma skin cancer will develop in the future.

Abstract
CXCL13 recruits CXCR5+ follicular helper T (Tfh) cells in inflammatory lesions to develop secondary lymphoid organs. Tfh cells activate B cells to produce antibodies during humoral immune responses. Indeed, as previous reports suggested, CXCR5+ cell numbers were increased in the peripheral blood of bullous pemphigoid (BP) patients when compared with healthy donors, and the ratio of CXCR5+ cells was positively correlated with the anti-BP180-NC16A titers. From the above findings, in this report, we hypothesized that a chemokine related to CXCR5+ cells, namely CXCL13, may play a role in the development of BP. We performed immunohistochemical staining of CXCR5, CXCL13, LL37, CXCL10 and CCL20 for 10 cases of BP and 10 cases of pemphigus vulgaris (PV), and quantitatively analyzed the staining by digital microscopy. Moreover, we investigated the CXCL10 and CXCL13 production in BP and PV patients by enzyme-linked immunosorbent assay. The immunomodulatory effects of LL37 on the production of T-helper 17-related chemokines were evaluated using monocyte-derived M2 macrophages. Immunohistochemical staining and digital microscopic analysis showed that the ratios of CXCR5+ , CXCL13+ and LL37+ cells in the dermis were significantly higher in BP patients than in PV patients. Notably, the ratio of CXCL13+ cells was positively correlated with the anti-BP180-NC16A titers. Moreover, the serum levels of CXCL13 were positively correlated with the anti-BP180-NC16A titers. Furthermore, CD163+ M2 macrophages stimulated by LL37 in vitro produced CXCL10 and CCL20. In the lesional skin of BP, CD163+ macrophages CXCL10 and CCL20 were produced. The serum levels of CXCL10 were negatively correlated with the anti-BP180-NC16A titers. The present study results indicate that the mechanism of the development of BP may involve the CXCL13/CXCR5-mediated migration of Tfh cells.
