Abstract
Many studies performed to date have implicated select microbes and dietary factors in a variety of cancers, yet the complexity of both these diseases and the relationship between these factors has limited the ability to translate findings into therapies and preventative guidelines. Here we begin by discussing recently published studies relating to dietary factors, such as vitamins and chemical compounds used as ingredients, and their contribution to cancer development. We further review recent studies, which display evidence of the microbial-diet interaction in the context of cancer. The field continues to advance our understanding of the development of select cancers and how dietary factors are related to the development, prevention, and treatment of these cancers. Finally, we highlight the science available in the discussion of common misconceptions with regards to cancer and diet. We conclude this review with thoughts on where we believe future research should focus in order to provide the greatest impact towards human health and preventative medicine.

Cancer-testis antigen lactate dehydrogenase C4 in hepatocellular carcinoma: a promising biomarker for early diagnosis, efficacy evaluation and prognosis prediction. Aging (Albany NY) 2020; 12:19455-19467. [PMID: 33035196 PMCID: PMC7732326 DOI: 10.18632/aging.103879] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Accepted: 06/22/2020] [Indexed: 01/24/2023]
Abstract
Expressions and clinical implications of cancer-testis antigen (CTA) lactate dehydrogenase (LDH)-C4 in hepatocellular carcinoma (HCC) have not been fully elucidated. Herein, expressions of LDHC mRNA in the serum and serum-derived exosomes of early-stage HCC patients were determined using qRT-PCR, and the expression of LDH-C4 protein in HCC tissues was detected using high-throughput tissue microarray analysis. It was found that positive rates of LDHC mRNA expressions in the serum and serum exosomes of HCC patients were 68% and 60%, respectively. The AUCs of serum and exosomal LDHC in differentiating HCC patients from healthy controls were 0.8382 and 0.9451, respectively. The serum and exosomal LDHC levels in HCC patients in the treatment group were higher than the levels in the preliminary diagnosis group, but lower than those in the recurrence group. Survival analysis showed that the expression of LDH-C4 was negatively correlated with the prognosis of HCC. The Cox regression analysis showed that an LDH-C4 level was an independent risk factor for the prognosis of HCC patients. Therefore, serum and exosomal LDHC can be used as a biomarker for early diagnosis, efficacy evaluation and recurrence prediction of HCC. Moreover, LDH-C4 can be used as an important reference indicator for monitoring the prognosis of HCC.

Anal Bioanal Chem 2018; 410:2517-2531. [PMID: 29492623 DOI: 10.1007/s00216-018-0883-3] [Citation(s) in RCA: 49] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2017] [Revised: 12/25/2017] [Accepted: 01/15/2018] [Indexed: 01/08/2023]
Abstract
A validated liquid chromatography-tandem mass spectrometry method was developed for the simultaneous determination of D- and L-amino acids in human serum. Under the optimum conditions, except for DL-proline, L-glutamine, and D-lysine, the enantioseparation of the other 19 enantiomeric pairs of proteinogenic amino acids and nonchiral glycine was achieved with a CROWNPAK CR-I(+) chiral column within 13 min. The lower limits of quantitation for L-amino acids (including glycine) and D-amino acids were 5-56.25 μM and 0.625-500 nM, respectively, in human serum. The intraday precision and interday precision for all the analytes were less than 15%, and the accuracy ranged from -12.84% to 12.37% at three quality control levels. The proposed method, exhibiting high rapidity, enantioresolution, and sensitivity, was successfully applied to the quantification of D- and L-amino acid levels in serum from hepatocellular carcinoma patients and healthy individuals. The serum concentrations of L-arginine, L-isoleucine, L-aspartate, L-tryptophan, L-alanine, L-methionine, L-serine, glycine, L-valine, L-leucine, L-phenylalanine, L-threonine, D-isoleucine, D-alanine, D-glutamate, D-glutamine, D-methionine, and D-threonine were significantly reduced in the hepatocellular carcinoma patients compared with the healthy individuals (P < 0.01). D-Glutamate and D-glutamine were identified as the most downregulated serum markers (fold change greater than 1.5), which deserves further attention in hepatocellular carcinoma research.

Abstract
AMP-activated protein kinase (AMPK) is an important mediator in maintaining cellular energy homeostasis. AMPK is activated in response to a shortage of energy. Once activated, AMPK can promote ATP production and regulate metabolic energy. AMPK is a known target for treating metabolic syndrome and type-2 diabetes; however, recently AMPK is emerging as a possible metabolic tumor suppressor and target for cancer prevention and treatment. Recent epidemiological studies indicate that treatment with metformin, an AMPK activator reduces the incidence of cancer. In this article we review the role of AMPK in regulating inflammation, metabolism, and other regulatory processes with an emphasis on cancer, as well as, discuss the potential for targeting AMPK to treat various types of cancer. Activation of AMPK has been found to oppose tumor progression in several cancer types and offers a promising cancer therapy. This review evaluates the evidence linking AMPK with tumor suppressor function and analyzes the molecular mechanisms involved. AMPK activity opposes tumor development and progression in part by regulating inflammation and metabolism.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common causes of cancer related mortality worldwide. The incidence of HCC has been increasing annually. Viral infection, alcohol usage, and other causes of cirrhosis have been identified as major risk factors for HCC development. The underlying pathogenesis has not been as well defined. There have been multiple hypotheses to the specific mechanisms of hepatocarcinogenesis and they share the common theme of chronic inflammation, increase oxidative stress, and genomic alteration. Therapeutic options of HCC have been primarily local and/or regional including transplantation, resection, and radial frequency ablation, chemoembolization or radio-embolization. For unresectable or metastatic disease, the options are limited. Conventional chemotherapeutic options have been noted to have limited benefit. Sorafenib has been the one and only systemic therapy which has demonstrated modest overall survival benefit. This has led to more extensive research with focus on targeted therapy. Numerous pre-clinical and early phase clinical studies have been noted but failed to show efficacy in later phase clinical trials. In an effort to identify new potential therapeutic options, new understanding of underlying pathways to hepatocarcinogenesis should be one of the main focuses. This leads to development of more molecularly targeted agents to specific pathways, and immunotherapy. This article provides a review of major studies of molecular targeted agents which attempts to target these specific pathways in HCC.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) significantly contributes to the global burden of cancer. Liver cancer is the third most frequent cause of cancer-related death with HCC representing more than 90% of primary liver cancers. The majority of patients are not only affected by the malignant disease but do also suffer from chronic liver disease. Therefore, several factors impact on the prognosis of patients with HCC, including tumor-related factors, liver function and patient-related factors such as performance status and other comorbidities. The nutritional status is of high significance for the patients' performance status, the tolerance of tumor-targeting therapy and the prognosis of cancer of any type and is specially referenced in HCC. This overview is on current concepts on the role of nutritional factors in hepatocarcinogenesis and the role of nutrition in patients affected by HCC. SUMMARY Nutritional status and composition of diet are relevant factors related to the risk of HCC. They also have an important role concerning the prognosis of patients with HCC. Besides risk factors, several macro- and micronutrient components have been found to be inversely correlated with the risk of HCC. To prevent disease progression to liver cirrhosis or HCC in patients with nonalcoholic steatohepatitis, it is crucial to optimize the metabolic state. KEY MESSAGE AND PRACTICAL IMPLICATION Evidence from well-designed prospective interventional trials with the aim to reduce the HCC incidence or to prolong survival in patients with HCC based on nutritional modification is still to be generated.

Zhou X, Zhu HQ, Ma CQ, Li HG, Liu FF, Chang H, Lu J. Two polymorphisms of USF1 gene (-202G>A and -844C>T) may be associated with hepatocellular carcinoma susceptibility based on a case-control study in Chinese Han population. Med Oncol 2014; 31:301. [PMID: 25367853 DOI: 10.1007/s12032-014-0301-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2014] [Accepted: 10/23/2014] [Indexed: 02/06/2023]
Abstract
Hepatocellular carcinoma (HCC) is a prototype of liver cancer, which is closely related to manifested metabolism of lip and glucose. Upstream transcription factor 1 (USF1) is an important transcription factor in human genome, and it regulates the expression of multiple genes associated with lipid and glucose metabolism. This study aims at investigating the correlation between seven common USF1 polymorphisms (i.e., -1994 G>A, -202 G>A, 7998 A>G, -844 C>T, 9042 C>G, 9441 T>C, and -2083 G>A) and the risk of HCC. Elucidation of the interaction might be of vital importance to the diagnosis and prognosis of HCC. One hundred and fifty-five HCC patients and 160 healthy controls from a Chinese Han population were involved in this study. Tag single-nucleotide polymorphisms (SNPs) were identified with reference to CBI-dbSNP and HapMap databases. DNA was extracted from blood samples, and matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was conducted to determine the polymorphisms of USF1. Odds ratio (OR) and 95% confidence interval were applied to evaluate the difference of genotype distribution. Seven SNPs were selected to be representatives. No significant difference was observed concerning -1994 G>A, 7998 A>G, 9042 C>G, 9441 T>C, and -2083 G>A polymorphisms (all P > 0.05). A significantly elevated genotype frequency regarding -202 G>A polymorphism was observed in HCC patients [AA vs. GG: OR 2.13 (1.13-4.01), P = 0.019; AA vs. GG+GA: OR 2.22 (1.32-3.75), P = 0.003; A allele vs. G allele: OR 1.46 (1.07-2.01), P = 0.018]. Subjects carrying mutant -844 C>T genotypes also had a higher risk of HCC [CT vs. CC: OR 1.88 (1.17-3.04), P = 0.009; CT+TT vs. CC: OR 1.83 (1.17-2.86), P = 0.008; T allele vs. C allele: OR 1.49 (1.06-2.09), P = 0.020]. Further studies are recommended to validate our findings in different ethnicity and to clarify the functional relationship between USF1 polymorphisms and the susceptibility of HCC.

The long noncoding RNA expression profile of hepatocellular carcinoma identified by microarray analysis. PLoS One 2014; 9:e101707.

Abstract
Background Thousands of long noncoding RNAs (lncRNAs) have been reported in mammalian genomes. These RNAs represent an important subset of pervasive genes involved in a broad range of biological functions. Aberrant expression of lncRNAs is associated with many types of cancers. Here, in order to explore the potential lncRNAs involved in hepatocellular carcinoma (HCC) oncogenesis, we performed lncRNA gene expression profile analysis in 3 pairs of human HCC and adjacent non-tumor (NT) tissues by microarray. Methodology Differentially expressed lncRNAs and mRNAs were detected by human lncRNA microarray containing 33,045 lncRNAs and 30,215 coding transcripts. Bioinformatic analyses (gene ontology, pathway and network analysis) were applied for further study of these differentially expressed mRNAs. By qRT-PCR analysis in nineteen pairs of HCC and adjacent normal tissues, we found that eight lncRNAs were aberrantly expressed in HCC compared with adjacent NT tissues, which is consistent with microarray data. Conclusions We identified 214 lncRNAs and 338 mRNAs abnormally expressed in all three HCC tissues (Fold Change ≥2.0, P<0.05 and FDR <0.05) with the genome-wide lncRNAs and mRNAs expression profile analysis. The lncRNA-mRNA co-expression network was constructed, which may be used for predicting target genes of lncRNAs. Furthermore, we demonstrated for the first time that BC017743, ENST00000395084, NR_026591, NR_015378 and NR_024284 were up-regulated, whereas NR_027151, AK056988 and uc003yqb.1 were down-regulated in nineteen pairs of HCC samples compared with adjacent NT samples. Expression of seven lncRNAs was significantly correlated to their nearby coding genes. In conclusion, our results indicated that the lncRNA expression profile in HCC was significantly changed, and we identified a series of new hepatocarcinoma associated lncRNAs. These results provide important insights about the lncRNAs in HCC pathogenesis.
