MATERIALS AND METHODS The relevant literature on insect tea was obtained from scientific database, including Elsevier, PubMed, Springer, Wiley, Web of Science, Google Scholar, SciFinder, China National Knowledge Infrastructure (CNKI), Baidu Scholar, Wanfang Database, etc. In addition, pertinent information available in Ph.D theses, MSc. dissertations, books, records, and some classical Chinese herbal literature were also included. The references cited in this review were up to September 2022. RESULTS Insect tea has been traditionally used as popular beverage with various medicinal functions in the ethnic minority regions in Southwest China for centuries. At present, ten types of insect teas are recorded in different regions. Ten species tea-producing insect and fifteen species host plants are used to in the production of the tea. Insect teas were rich in various nutrients including proteins, carbohydrates, fat, minerals, dietary fiber and Vitamins. A total of 71 compounds have been isolated from insect teas, mainly including flavonoids, ellagitannins, chlorogenic acids and other phenolic compounds as well as the alkaloids. Modern studies demonstrated that insect tea had a variety of pharmacological activities in vitro and in vivo, such as anti-diabetic, lipid-lowing and anti-hypertensive, hepato-protective, gastro-intestinal promoting, anti-cancer, anti-mutagenic, antioxidant, and anti-aging activity, etc. Moreover, existing experimental results showed that insect teas are non-toxicity and biological safety. CONCLUSION Insect tea is a unique and niche product originated in the ethnic minority regions of Southwest China with various health-promoting benefits. Phenolics including flavonoids, ellagitannins, chlorogenic acids were reported as the main chemical constituents identified from insect tea. Multiple pharmacological activities of insect tea have been reported, which indicated that it had great potential for further development and application as drugs and health-promoting products.

Long X, Wang P, Zhou Y, Wang Q, Ren L, Li Q, Zhao X. Preventive effect of Lactobacillus plantarum HFY15 on carbon tetrachloride (CCl 4 )-induced acute liver injury in mice. J Food Sci 2022; 87:2626-2639. [PMID: 35534088 DOI: 10.1111/1750-3841.16171] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2021] [Revised: 04/06/2022] [Accepted: 04/11/2022] [Indexed: 01/15/2023]
Abstract
Carbon tetrachloride (CCl4 ) is the main chemical causing liver damage. In this experiment, the effect of Lactobacillus plantarum HFY15 treatment on CCl4 -induced acute liver injury was investigated using mice. Fifty adult mice were randomized into five study groups, each group with 10 ml kg-1 saline, 50 mg kg-1 silymarin, and 109 CFU kg-1 L. plantarum HFY15 and LDSB per day, and all the mice expect the normal group were injected 0.8% CCl4 (10 ml kg-1 ) on the 14th day. Following the 16 h induction of the liver injury, various biochemical markers were assessed for blood and liver tissue. After L. plantarum HFY15 treatment, the content of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglycerides (TG), malondialdehyde (MDA), and reactive oxygen species (ROS) in serum decreased by 67.7%, 65.0%, 41.9%, 59.5%, and 51.5%, respectively, and the level of antioxidant enzymes (total superoxide dismutation [T-SOD], catalase [CAT], glutathione [GSH]) increased by more than twofold. Pro-inflammatory cytokine interleukin-6 (IL-6), interferon-γ (INF-γ), and tumor necrosis factor-α (TNF-α) decreased by more than 45% in serum and live. What is more, L. plantarum HFY15 increased the expression of antiapoptosis genes Bcl-2 by eightfold, inhibiting the expression of proapoptotic genes Caspase-3 and Bax by about threefold. Lactobacillus plantarum HFY15 has obvious protective effects on CCl4 -induced liver injury by inhibiting oxidation, reducing the release of inflammatory factors, and exerting suppressive effect on apoptotic process in the CCl4 -induced liver injury. Lactobacillus plantarum HFY15 can be developed as edible lactic acid bacteria for preventing liver toxicity. PRACTICAL APPLICATION: L. plantarum HFY15 can alleviate liver injury caused by carbon tetrachloride toxicity through antioxidant, anti-inflammatory and anti-apoptotic pathways.

Abstract
Ilex kudingcha C.J. Tseng tea and insect tea, as traditional Chinese teas, are favored for their original craftsmanship, unique flavor, and biological functionality. In this study, ultra high-performance liquid chromatography-triple quadrupole mass spectrometry (UHPLC-QqQ-MS) was used to analyze the bioactive components of the extracts of Ilex kudingcha and insect tea, and D-galactose-induced aging mice were used to compare the in vivo anti-aging effects of Ilex kudingcha and insect tea extracts. The results were remarkable, UHPLC-QqQ-MS analysis showed that ITP contains 29 ingredients, while IKDCP contains 26 ingredients. However, due to the large differences in the content of the main chemical components in IKDCP and ITP, the effects are equally different. At the same time, the in vivo research results suggesting that the anti-aging effects of IKDCP and ITP (500 mg/kg) include the regulation of viscera indices of major organs; improvement in liver, skin, and spleen tissue morphology; decreased production of inflammatory cytokines; up regulation of SOD, CAT, GSH, GSH-PX, and T-AOC and down regulation of NO and MDA levels in serum and liver tissue; reductions in the concentration of pro-inflammatory factors, and increases in the concentration of anti-inflammatory factor. RT-qPCR and western blot assay also showed that IKDCP and ITP affect anti-aging by regulating the gene and protein expression of GSH-PX, GSH1, SOD1, SOD2, and CAT. The overall results indicate that ITP is more effective in treating oxidative damage in aging mice induced by D-galactose. Thus, ITP appears to be an effective functional drink owing to its rich nutritional components and anti-aging activities.

Abstract
This study was conducted to investigate the preventative effect of Lactobacillus fermentum HFY06 on carbon tetrachloride (CCl4)-induced liver injury in Kunming mice. Mice were treated with HFY06, then liver damage was induced using CCl4. Evaluation indicators included the activities of aspartate aminotransferase (AST), triglycerides (TG), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) in serum; cytokines levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in serum; and related gene expressions of nuclear factor-κB (NF-κB), TNF-α, cyclooxygenase-2 (COX-2), copper/zinc superoxide dismutase (Cu/Zn-SOD), manganese superoxide dismutase (Mn-SOD), and catalase (CAT). Liver tissue was stained with hematoxylin and eosin for pathological analysis. Compared with the model group, HFY06 reduced the liver index, increased the serum SOD and GSH-Px activities, and reduced the AST, TG, and MDA activities in the mice. Inflammation-related IL-6, TNF-α and IFN-γ levels were also reduced after treatment with a high dose of HFY06. Pathological observation showed that CCl4 damaged the mouse livers, which were significantly improved after treatment with silymarin and HFY06. qPCR also confirmed that the high dose of HFY06 (109 colony-forming units [CFU] per kg per day) upregulated the mRNA expression of the antioxidant genes, Cu/Zn-SOD, Mn-SOD, and CAT, in the liver tissue and downregulated the mRNA expression of the inflammatory factors, NF-κB, TNF-α and COX-2, but HFY06 was less effective than silymarin. These findings indicate that HFY06 prevented CCl4-induced liver damage in vivo but was less effective than silymarin. Thus, HFY06 may have a potential role in treating liver diseases. This study was conducted to investigate the preventative effect of Lactobacillus fermentum HFY06 on carbon tetrachloride (CCl4)-induced liver injury in Kunming mice.![]()

Abstract
Cancer is a worldwide epidemic and represents a major threat to human health and survival. Reactive oxygen species (ROS) play a dual role in cancer cells, which includes both promoting and inhibiting carcinogenesis. Tea remains one of the most prevalent beverages consumed due in part to its anti- or pro-oxidative properties. The active compounds in tea, particularly tea polyphenols, can directly or indirectly scavenge ROS to reduce oncogenesis and cancerometastasis. Interestingly, the excessive levels of ROS induced by consuming tea could induce programmed cell death (PCD) or non-PCD of cancer cells. On the basis of illustrating the relationship between ROS and cancer, the current review discusses the composition and efficacy of tea including the redox-relative (including anti-oxidative and pro-oxidative activity) mechanisms and their role along with other components in preventing and treating cancer. This information will highlight the basis for the clinical utilization of tea extracts in the prevention or treatment of cancer in the future.

The complete mitochondrial genome of a medicinal insect, Hydrillodes repugnalis (Lepidoptera: Noctuoidea: Erebidae), and related phylogenetic analysis. Int J Biol Macromol 2018; 123:485-493. [PMID: 30359659 DOI: 10.1016/j.ijbiomac.2018.10.149] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Revised: 10/21/2018] [Accepted: 10/21/2018] [Indexed: 02/08/2023]
Abstract
The complete mitochondrial genome (mitogenome) of an important medicinal insect Hydrillodes repugnalis (Lepidoptera: Noctuoidea) was sequenced and analyzed. The mitogenome is circular with 15,570 bp long, and shows typical gene content and arrangement. Nucleotide composition is highly biased toward A + T nucleotides (81.1%). All protein-coding genes (PCGs) initiate with canonical start codon ATN, except for cox1 being CGA. The typical stop codon TAA is used for most PCGs, while the nad4l uses the TAG, and cox1 and cox2 use incomplete termination codon T. All tRNAs have a typical clover-leaf structure, except for trnS1 (AGN) lacking the dihydrouridine arm. Comparative mitogenome analysis showed that the motif "ATGATAA" between atp8 and atp6, and the motif "ATACTAA" between trnS2 and nad1 are commonly present in noctuoid mitogenomes. In A + T-rich regions, the motif "ATAGA" and subsequent poly-T structure, the motif "ATTTA" and followed macrosatellite (AT)n element and an "A"-rich 3' end upstream of the trnM gene can be recognized across noctuoid mitogenomes. Phylogenetic analyses showed that H. repugnalis is nested into the Erebidae clade, consistently being sister to the Aganainae. Within Noctuoidea, the (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))) was consistently recovered firstly based on multiple mitochondrial datasets.
