Cell Signal 2023; 110:110833. [PMID: 37543098 DOI: 10.1016/j.cellsig.2023.110833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 07/17/2023] [Accepted: 07/30/2023] [Indexed: 08/07/2023]
Abstract
MicroRNAs (miRs) are 18-25 nucleotides non-coding RNAs, which contribute to tumorigenesis. Previous studies have demonstrated that miR-199a-3p is dysregulated in human nasopharyngeal carcinoma (NPC), but its role in NPC progression still largely unknown. The current study aimed to determine the potential role of miR-199a-3p in NPC progression and the underlying mechanisms. In this study, miR-199a-3p was found to be prominently down-regulated in NPC tissues and cells. The cellular assay showed that transfection of miR-199a-3p markedly repressed the migration, invasion and induced epithelial-mesenchymal transition (EMT) in both 5-8F and CNE-2 cell lines. By dual-luciferase reporter, western blotting and gas chromatography assays, we found that SCD1 is not only highly expressed in NPC tissues and negatively associated with the prognosis of NPC patients but also can be apparently downregulated by miR-199a-3p in NPC cells, suggesting that SCD1 is a direct target gene of miR-199a-3p. Moreover, inhibition of miR-199a-3p expression activated PI3K/Akt signaling and up-regulated the expression of MMP-2. With tumor xenograft models in nude mice, we also showed that miR-199a-3p repressed tumor growth in vivo. Our study demonstrated that miR-199a-3p inhibited migration and invasion of NPC cells through downregulating SCD1 expression, thus providing a potential target for the treatment of NPC.

Tumor miRNA expression profile is related to vestibular schwannoma growth rate. Acta Neurochir (Wien) 2020; 162:1187-1195. [PMID: 32016588 DOI: 10.1007/s00701-020-04238-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Accepted: 01/18/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVE Our objective was to investigate if the tumor microRNA (miRNA) expression profile was related to tumor growth rate. Growth-related miRNAs might be potential targets for future therapeutic intervention. MATERIAL AND METHODS Tumor tissue was sampled during surgery of patients with a sporadic vestibular schwannoma. Tumor growth rate was determined by tumor measurement on the two latest pre-operative MRI scans. Tumor miRNA expression was analyzed using the Affymetrix Gene Chip® protocol, and CEL files were generated using GeneChip® Command Console® Software and normalized using Partek Genomics Suite 6.5. The CEL files were analyzed using the statistical software program R. Principal component analysis, affected gene ontology analysis, and analysis of miRNA expression fold changes were used for analysis of potential relations between miRNA expression profile and tumor growth rate. RESULTS AND CONCLUSION Tumor miRNA expression is related to the growth rate of sporadic vestibular schwannomas. Rapid tumor growth is associated with deregulation of several miRNAs, including upregulation of miR-29abc, miR-19, miR-340-5p, miR-21, and miR-221 and downregulation of miR-744 and let-7b. Gene ontologies affected by the deregulated miRNAs included neuron development and differentiation, gene silencing, and negative regulation of various biological processes, including cellular and intracellular signaling and metabolism.

Abstract
Introduction: Cutaneous melanoma is the deadliest form of skin cancer, with a dramatic increase in the incidence rate worldwide over the past decade. Early detection has been shown to improve the outcome of melanoma patients. The identification of noninvasive biomarkers able to identify melanoma at an early stage remains an unmet clinical need. Circulating miRNAs (c-miRNAs), small non-coding RNAs, appear as potential ideal candidate biomarkers due to their stability in biological fluids and easy detectability. Moreover, c-miRNAs are reported to be heavily deregulated in cancer patients.Areas covered: This review examines evidence of the specific c-miRNAs or panels of c-miRNAs reported to be useful in discriminating melanoma from benign cutaneous lesions.Expert opinion: Although the interesting reported by published studies, the non-homogeneity of detection and normalization methods prevents the individuation of single c-miRNA or panel of c-miRNAs that are specific for early detection of cutaneous melanoma. In the future, prospective wide and well-designed clinical trials will be needed to validate the diagnostic potential of some of the c-miRNA candidates in clinical practice.

Abstract
BACKGROUND Nowadays, the combination of microRNA (miR) is attracting increased attention in clinical cancer trials. However, the clinical use of miR is highly limited because of certain properties such as instability, low-specificity distribution, and metabolic toxicity. METHODS In order to improve the anti-tumor efficacy and reduce the side effects of miR in treating melanoma, a combination of graphene oxide (GO), chitosan (CS), and a cellular penetrating peptide, MPG, was prepared with solid dispersion method in this research. The research has analyzed the specific components of nano drug-loading complexes GO-CS and GO-CS-MPG through characterization research and confirmed the bio-safety of the carrier material GO-CS-MPG. RESULTS The GO-CS-MPG-miR33a/miR199a nano drug-loading complex was successfully constructed and its medical effectiveness was verified. Through the subcutaneous tumor implantation experiment, an evident effect of the drug-loading complex in inhibiting melanoma cells was proven. CONCLUSION Results suggest that GO-CS-MPG may have potential applications in melanoma therapy.

Abstract
MicroRNA (miR) are a class of small non-coding RNA that are able to inhibit gene expression by directly binding to the 3′ untranslated region (UTR) of their target mRNA and thus promote translational repression or mRNA degradation. Recently, miR-9 was reported to have a suppressive role in malignant melanoma; however, the underlying mechanism remains largely unclear. In the present study, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blotting were used to examine the mRNA and protein expression levels in malignant melanoma tissues and cell lines. The MTT assay and wound healing assay were used to examine the cell viability, proliferation and migratory capacities. Bioinformatics prediction and luciferase reporter assay were performed to investigate the relationship between miR-9 and its potential target gene. The present data revealed that miR-9 expression was significantly downregulated in malignant melanoma tissues when compared with their matched adjacent non-tumor tissues. Furthermore, the expression levels of miR-9 were reduced in malignant melanoma cell lines when compared with human normal skin HACAT cells. Moreover, the ectopic expression of miR-9 significantly suppressed the proliferation and migration of malignant melanoma cells, accompanied with a remarkable decrease in the protein expression levels of sirtuin 1 (SIRT1), which were markedly upregulated in malignant melanoma tissues and cell lines. Additionally, restoration of SIRT1 reversed the suppressive effects of miR-9 on the proliferation and migration of malignant melanoma cells. Luciferase reporter assay data further identified SIRT1 as a direct target gene of miR-9. To conclude, the present findings indicate that miR-9 has a suppressive role in malignant melanoma cell viability and migration, at least in part, via directly inhibiting the protein expression of its target gene, SIRT1. Therefore, miR-9 may serve as a potential candidate for the treatment of malignant melanoma.

Abstract
Prostate cancer (PC) is the most common and the second leading cause of cancer-related death among American men. Early diagnosis is a prerequisite to improving therapeutic benefits. However, the current clinical biomarkers for PC do not reliably decipher indolent PC from other urogenital disorders. Thus, effective clinical intervention necessitates development of new biomarkers for early detection of PC. The present study aimed to identify the miRNA signature in organ-confined (Gleason Score 6) prostate tumors. MicroRNA (miRNA/miR) array analysis identified 118 upregulated and 73 downregulated miRNAs in microdissected tumors in comparison to matched neighboring normal prostate epithelium. The miRs-Plus-A1083, -92b-5p, -18a-3p, -19a-3p, -639, -3622b-3p, -3189-3p, -155-3p, -410, -1179, 548b-5p, and -4469 are predominantly expressed (7-11-fold), whereas miRs-595, 4490, -3120-5p, -1299, -21-5p, -3677-3, -let-7b-5p, -5189, 3-121-5p, -4518, -200a-5p, -3682-5p, -3689d, -3149 represent the most downregulated (12-113-fold) miRNAs in microdissected prostate tumors. The array expression profile of selected miRNA signature and their potential mRNA targets was validated by qRT-PCR analysis in PC cell lines. Integrated in silico and computational prediction analyses demonstrated that the dysregulated miRNA signature map to key regulatory factors involved in tumorigenesis, including cell cycle, apoptosis, and p53 pathways. The newly identified miRNA signature has potential clinical utility as biomarkers, prognostic indicators, and therapeutic targets for early detection of PC. Further studies are needed to assess the functional significance and clinical usefulness of the identified miRNAs. Impact Statement To our knowledge his is the first study of identifying miRNA signatures in microdissected indolent (Gleason score 6) prostate cancer in comparison to matched normal prostate epithelium. By employing in silico and computational prediction analysis, the study provides a landscape of potential miRNA targets and key cellular pathways involved in prostate tumorigenesis. Identification if miRNAs and their relevant targets and pathways pave the way for underpinning their mechanistic role of miRNAs in human prostate tumorigenesis, and possibly other human cancers. Importantly, the outcome of the study has important clinical implications for the management of prostate cancer, including the use of miRNA(s) as biomarkers for early detection of prostate cancer.

Abstract
MicroRNAs (miRs) are a class of small noncoding RNAs that negatively regulate the gene expression by directly binding to the 3' untranslated region of their target mRNA, thus resulting in mRNA degradation or translational repression. miR-9 has recently been demonstrated to play a role in the development and progression of malignant melanoma (MM), but the regulatory mechanism of miR-9 in the malignant phenotypes of MM still remains largely unknown. In this study, a total of 73 pairs of MM tissues and adjacent normal tissues were collected. Real-time reverse transcription polymerase chain reaction and Western blot were used to detect the mRNA and protein expression of miR-9. MTT assay, wound healing assay, and transwell assay were conducted to determine the cell proliferation, migration, and invasion. Luciferase reporter assay was used to determine the targeting relationship between miR-9 and NRP1. Our data demonstrated that miR-9 expression was significantly downregulated in MM tissues compared with that in adjacent normal tissues. The decreased miR-9 level was significantly associated with the tumor stage and metastasis of MM. We also found that the expression level of miR-9 was decreased in MM cell lines (G361, B16, A375, and HME1) compared with normal skin HACAT cells. Ectopic expression of miR-9 led to a significant decrease in the ability of proliferation, migration, and invasion in A375 cells. NRP1 was further identified as a direct target gene of miR-9, and the protein expression of NRP1 was negatively regulated by miR-9 in A375 cells. Furthermore, overexpression of NRP1 reversed the suppressive effects of miR-9 on the malignant phenotypes of A375 cells. In vivo study revealed that miR-9 overexpression decreased the tumor growth, while overexpression of NRP1 increased MM growth. In summary, our findings suggest that the miR-9/NRP1 axis may serve as a potential target for the treatment of MM.

Abstract
Melanoma cells release different types of extracellular vesicles (EVs) into the extracellular milieu that are involved with communication and signaling in the tumor microenvironment. Subsets of EVs include exosomes, microvesicles, and apoptotic bodies that carry protein and genetic (RNA) cargos. To define the contribution of the RNA cargo of melanoma cell derived EVs we performed small RNA sequencing to identify different small RNAs in the EV subsets. Using validated centrifugation protocols, we separated these EV subsets released by the melanoma cell line MML-1, and performed RNA sequencing with the Ion Torrent platform. Various, but different, non-coding RNAs were detected in the EV subsets, including microRNA, mitochondrial associated tRNA, small nucleolar RNA, small nuclear RNA, Ro associated Y-RNA, vault RNA and Y-RNA. We identified in total 1041 miRNAs in cells and EV subsets. Hierarchical clustering showed enrichment of specific miRNAs in exosomes, including hsa-miR-214-3p, hsa-miR-199a-3p and hsa-miR-155-5p, all being associated with melanoma progression. Comparison of exosomal miRNAs with miRNAs in clinical melanoma samples indicate that multiple miRNAs in exosomes also are expressed specifically in melanoma tissues, but not in benign naevi. This study shows for the first time the presence of distinct small RNAs in subsets of EVs released by melanoma cells, with significant similarities to clinical melanoma tissue, and provides unique insights into the contribution of EV associated extracellular RNA in cancer.

Abstract
BACKGROUND Our previous findings showed that miR-33 expressed abnormally in clinical specimens of melanoma, but the exact molecular mechanism has not been elucidated. OBJECT To determine miR-33's roles in melanoma and confirm whether HIF-1α is a direct target gene of miR-33a. METHODS First miR-33a/b expression levels were detected in HM, WM35, WM451, A375 and SK-MEL-1. Then lentiviral vectors were constructed to intervene miR-33a expression in melanoma cells. Cell proliferation, invasion and metastasis were detected. A375 cells mice model was performed to test the tumorigenesis of melanoma in vivo. Finally the dual reporter gene assay was carried out to confirm whether HIF-1α is a direct target gene of miR-33a. RESULTS MiR-33a/b exhibited a lower expression in WM35, WM451, A375 and SK-MEL-1 of the metastatic skin melanoma cell lines than that in HM. Then inhibition of miR-33a expression in WM35 and WM451 cell lines could promote cell proliferation, invasion and metastasis. Conversely, increased expression of miR-33a in A375 cells could inhibit cellproliferation, invasion and metastasis. In vivo tests also confirmed that overexpression of miR-33a in A375 cells significantly inhibited melanoma tumorigenesis. Finally, we confirmed that HIF-1α is a direct target gene of miR-33a. CONCLUSION The newly identified miR-33a/HIF-1α axis might provide a new strategy for the treatment of melanoma.

Abstract
Ceramide synthases (CerSs) have been shown to regulate numerous aspects of cancer development. CerS6 has been suggested to be involved in cancer etiology. However, little is known concerning the exact effect of CerS6 on the malignant behavior of melanoma, including glycolysis, proliferation and invasion. In the present study, we found that the expression of CerS6 was low in the melanoma cell lines, including WM35, WM451 and SK-28, and the expression level was related to the malignanct behavior of the melanoma cell lines. We constructed overexpression and silencing models of CerS6 in three melanoma cell lines and found that silencing of CerS6 promoted the ability of proliferation and invasion in the melanoma cell lines. Additionally, downregulation of CerS6 upregulated the activity of glycolysis-related enzyme, and enhanced the expression of glycolysis-related genes, including GLUT1 and MCT1. Furthermore, we identified the genes whose expression levels were changed after silencing of CerS6 by gene microarray. The expression of glycolysis-related gene SLC2A1 (also known as GLUT1) was found to be upregulated, while notably WNT5A was downregulated. The altered expression of GLUT1 and WNT5A was verified by qPCR and western blotting. Furthermore, silencing of GLUT1 in the melanoma cells resulted in the increased expression of WNT5A and the decreased ability of invasion and proliferation in the melanoma cells. Collectively, silencing of CerS6 induced the increased expression of GLUT1, which downregulated the expression of WNT5A and enhanced the invasion and proliferation of melanoma cells. Thus, CerS6 may provide a novel therapeutic target for melanoma treatment.

Anti-cancer effects of enteric-coated polymers containing mistletoe lectin in murine melanoma cells in vitro and in vivo. Mol Cell Biochem 2015; 408:73-87. [PMID: 26152904 DOI: 10.1007/s11010-015-2484-1] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2015] [Accepted: 06/18/2015] [Indexed: 02/03/2023]
Abstract
In this study, we evaluated the effects of Korean mistletoe (Viscum album L. var. coloratum) coated with a biodegradable polymer (Eudragit(®)) wall on the growth of mouse melanoma in vivo. Oral administration of 4% (430 mg/kg/day) enteric-coated mistletoe resulted in a significant reduction in tumor volume on day 14 compared to the negative control group in B16F10 melanoma-inoculated BDF1 mice. When we measured the survival rate, enteric-coated mistletoe-received mice had a higher survival rate after day 12. Also, we investigated the mechanism involving the cancer cell growth inhibition when melanoma cells were treated with Korean mistletoe lectin (Viscum album L. var. coloratum agglutinin, VCA) and its extract in vitro. As a result, a significant G0/G1 arrest was observed in both B16BL6 and B16F10 melanoma cells with VCA or mistletoe extract. In addition, VCA or mistletoe extract induced an increase in both early and late apoptosis in cells. When we studied the molecular mechanism, our results showed that VCA and mistletoe extract can increase activated multiple caspases (caspase-1, 3, 4, 5, 6, 7, 8, and 9), dose-dependently. We also found out that VCA and mistletoe treatment causes a significant decrease in the expression of procaspase-3 and 8.

Abstract
PURPOSE To confirm whether flotillin 2 (FLOT2) is a direct target of miR-34a and miR-34a/FLOT2 pathway plays a key role in melanoma proliferation and metastasis. METHODS First, miR-34a and FLOT2 expressions were both detected in human tissues and cell lines by qRT-PCR. Then, after transfection of mimics/inhibitor of miR-34a into melanoma cell lines, MTT, colony formation, scratch migration assays and transwell invasion assays were performed to evaluate the impact of miR-34a on cell proliferation and metastasis. Western blot, qRT-RCR and dual luciferase reporter gene assays were carried out to confirm whether FLOT2 is a direct target gene of miR-34a. In functional recovery experiments, proliferation and metastasis ability of WM35 and WM451 was tested after being co-transfected with miR-34a inhibitor/si-FLOT2 or miR-34a mimics/FLOT2 cDNA to confirm that FLOT2 is downregulated by miR-34a. RESULTS The miR-34a significantly lower-expressed in metastasis melanoma tissues compared to in situ melanoma, nevi and normal skin whereas FLOT2 has an opposite trend. The level of miR-34a and FLOT2 in different melanoma cell lines was also tested and found that metastatic melanoma cell lines has lower miR-34a expression and higher FLOT2 expression compare to in situ melanoma cell line. MiR-34a overexpression profoundly inhibits WM451 cell proliferation and metastasis, whereas miR-34a reduction had a promoting effect to proliferation and metastasis of WM35. Results of Western blot, qRT-RCR and dual luciferase reporter gene assays revealed that FLOT2 is a direct target gene of miR-34a. Furthermore, overexpression/blockage of FLOT2 could attenuate effect of miR-34a overexpression/inhibition which indicated miR-34a suppresses melanoma biological behavior partially through FLOT2 inhibition. CONCLUSIONS Our study confirmed that miR-34a is involved in the tumor inhibition of melanoma by directly targeting FLOT2 gene. This finding provides potential novel strategies for therapeutic interventions of melanoma.

Abstract
The study aimed to investigate the expression and significance of the plasma let-7 family in anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. Blood samples from 5 anti-NMDAR encephalitis patients and 5 negative controls were collected for microarray analysis. Blood samples from10 anti-NMDAR encephalitis patients, 10 anti-NMDAR encephalitis patients whose physical conditions have improved after 3 months of immunotherapy, 20 virus (meningitis) encephalitis patients, 20 tuberculosis (meningitis) encephalitis patients, 10 purulent (meningitis) encephalitis patients, 20 cerebral cysticercosis patients, 20 ischemic stroke patients, 20 intracerebral hemorrhage patients, 15 neuromyelitis optica patients, 15 multiple sclerosis patients, 15 moyamoya disease patients, and 20 negative controls were collected for real-time quantitative PCR (qRT-PCR) analysis. The expression levels of let-7a, let-7b, let-7d, and let-7f were significantly down-regulated in anti-NMDAR encephalitis compared with the negative controls (NC). The expression levels of let-7a, let-7d, and let-7f were significantly down-regulated in other nervous system diseases compared with the NC group while the expression level of let-7b was statistically insignificant in other nervous system diseases compared with the NC group. In addition, there was no significant dysregulation of let-7b in the anti-NMDAR encephalitis treatment group compared with the NC. Let-7b may be a potential diagnostic marker and an indicator that reflected the molecular mechanism of anti-NMDAR encephalitis.

Abstract
OBJECTIVE(S) Estrogen receptor-alpha (ERα) mediates estrogen action in regulation of different levels of the hypothalamic-pituitary-testis axis. It has a key role in spermatogenesis. Estrogen receptor alpha knock-out (ER koα) male mice were infertile and severe impairment in spermatogenesis and seminiferous tubules was observed. Recently, it has been reported that microRNA (miRNA) mir-100 and let-7b were predicted to target ERα gene. MiRNA are small, endogenous, single stranded RNA molecules that regulate gene expression and have been implicated in various disease states. It has been proved that some miRNAs expression is tissue- and disease-specific, giving potential for identifying miRNAs as a diagnostic tool. MATERIALS AND METHODS In this study, the change in the expression levels of mir-100, let-7b and ERα expression levels were evaluated in oligospermic infertile patients (n=43) compared to control fertile subjects (n=43). After washing and separating sperms, total RNA was isolated and then cDNA was synthesized. The expression levels of mir-100 and let-7b and ERα were evaluated by real time PCR. RESULTS Mir-100, let-7b levels were significantly higher than those in control group (P=0.008 and P=0.009, respectively). We have found that, ERα level was significantly decreased in comparison with normal group (P< 0.0001). CONCLUSION Changes in mir-100, let-7b and ERα expression levels in oligospermic patients may be associated with the susceptibility and progression of infertility. The results of this study indicate that miRNA can have a key role in spermatogenesis and might have a diagnostic and prognostic value in men infertility.

INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2014; 7:7182-90. [PMID: 25400815 PMCID: PMC4230055 DOI: pmid/25400815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 08/20/2014] [Accepted: 09/10/2014] [Indexed: 02/05/2023]
Abstract
MicroRNAs are regulatory factors that play important roles in tumor development, invasion and metastasis. Previously, we showed that miR-199a is abnormally expressed in clinical melanoma specimens and expression was closely associated with clinical features of metastasis. However, the exact molecular mechanisms by which miR-199a-5p influences melanoma invasion and metastasis remains unclear. In this study, we investigated gene expression changes of metastasis-associated genes in B16F10 melanoma cells following targeted silencing or overexpression of miR-199a-5p, using mouse tumor metastasis PCR arrays. Comparison of gene expression changes in miR-199a-5p-silenced versus overexpressing cells identified a set of upregulated genes (> 2-fold) including Cd44, Cdh1, Cxcr4, Etv4, Fxyd5, Rpsa, Mmp3, Myc, Rb1, Tcf20, Hprt1, Actb1 and downregulated genes (> 2-fold) including Ctsk, Itga7 and Tnfsf10. Regulation of a subset of these genes (Myc, Tnfsf10 and Cd44) following miR-199a-5p silencing or overexpression was validated by reverse transcription-polymerase chain reaction (RT-PCR) and western blot. In conclusion, our study demonstrates that miR-199a-5p regulates melanoma metastasis-related genes, and may provide a basis for the development of novel, molecularly targeted drugs.

Abstract
Melanoma is a very aggressive skin cancer with increasing incidence worldwide. MicroRNAs are small, noncoding RNAs that regulate gene expression of targeted gene(s). The hallmark of cancer model outlined by Hanahan and Weinberg offers a meaningful framework to consider the roles of microRNAs in melanoma development and progression. In this systematic review of the literature, we associate what is known about deregulation of microRNAs and their targeted genes in melanoma development with the hallmarks and characteristics of cancer. The diagnostic and therapeutic potential of microRNAs for future melanoma management will also be discussed.

Abstract
Despite recent advances, the treatment of malignant melanoma still results in the relapse of the disease, and second line treatment mostly fails due to the occurrence of resistance. A wide range of mutations are known to prevent effective treatment with chemotherapeutic drugs. Hence, approaches with biopharmaceuticals including proteins, like antibodies or cytokines, are applied. As an alternative, regimens with therapeutically active nucleic acids offer the possibility for highly selective cancer treatment whilst avoiding unwanted and toxic side effects. This paper gives a brief introduction into the mechanism of this devastating disease, discusses the shortcoming of current therapy approaches, and pinpoints anchor points which could be harnessed for therapeutic intervention with nucleic acids. We bring the delivery of nucleic acid nanopharmaceutics into perspective as a novel antimelanoma therapeutic approach and discuss the possibilities for melanoma specific targeting. The latest reports on preclinical and already clinical application of nucleic acids in melanoma are discussed.
