MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27238504. [PMID: 36500595 PMCID: PMC9740247 DOI: 10.3390/molecules27238504] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 11/27/2022] [Accepted: 11/29/2022] [Indexed: 12/12/2022]
Abstract
Hepatocellular carcinoma (HCC) is a poor-prognosis type of cancer with high resistance to chemotherapy, making the search for safe drugs a mandatory issue. Plant-derived products have potential to reduce negative side effects of cancer treatments. In this work, ability of a defatted methanolic extract of Alocasia gigantea leaves to fight HCC was evaluated in an animal model. Overall, treatment of HCC-induced mice with the methanolic extract at 150 mg/kg body weight for four consecutive weeks caused induction of autophagy through silencing of the relative expression of autophagy suppressor (mTOR) and inducement of autophagy markers (AMPK, Beclin-1, and LC-3). Moreover, it improved preservation of the hepatic histological architecture of the animals, with minor hepatocytic changes but scattered foci of hepatocytic apoptosis. Chemical profiling of the methanolic extract via ultra-high-performance liquid chromatography coupled to a diode array detector and an electrospray mass spectrometer (UHPLC-DAD-ESI-MS/MS) allowed identification of di-C-glycosyl flavones, mostly represented by 6-C-hexosyl-8-C-pentosyl apigenin isomers, which may possibly be associated with inducement of the autophagy pathway in HCC. Overall, these outcomes gave an initial visualization of the operative effect of some compounds in A. gigantea leaves that are potential treatment for HCC.

Abstract
The genus Alocasia (Schott) G. Don consists of 113 species distributed across Asia, Southeast Asia, and Australia. Alocasia plants grow in tropical and subtropical forests with humid lowlands. Featuring their large green heart-shaped or arrow-shaped ear leaves and occasionally red-orange fruit, they are very popular ornamental plants and are widely used as traditional medicines to treat various diseases such as jaundice, snake bite, boils, and diabetes. This manuscript critically analysed the distribution, traditional uses, and phytochemical contents of 96 species of Alocasia. The numerous biological activities of Alocasia species were also presented, which include anti-cancer, antidiabetic and antihyperglycaemic, antioxidant, antidiarrhoea, antimicrobial and antifungal, antiparasitic (antiprotozoal and anthelminthic), antinociceptive and anti-inflammatory, brine shrimp lethality, hepatoprotective, anti-hemagglutinin, anti-constipation and diuretic, and radioprotective activities as well as acute toxicity studies. Research articles were acquired by the accessing three scientific databases comprising PubMed, Scopus, and Google Scholar. For this review, specific information was obtained using the general search term "Alocasia", followed by the "plant species names" and "phytochemical" or "bioactivity" or "pharmacological activity". The accepted authority of the plant species was referred from theplantlist.org. Scientific studies have revealed that the genus is mainly scattered throughout Asia. It has broad traditional benefits, which have been associated with various biological properties such as cytotoxic, antihyperglycaemic, antimicrobial, and anti-inflammatory. Alocasia species exhibit diverse biological activities that are very useful for medical treatment. The genus Alocasia was reported to be able to produce a strong and high-quality anti-cancer compound, namely alocasgenoside B, although information on this compound is currently limited. Therefore, it is strongly recommended to further explore the relevant use of natural compounds present in the genus Alocasia, particularly as an anti-cancer agent. With only a few Alocasia species that have been scientifically studied so far, more attention and effort is required to establish the link between traditional uses, active compounds, and pharmacological activities of various species of this genus.

Inhibited HDAC3 promotes microRNA-376c-3p to suppress malignant phenotypes of gastric cancer cells by reducing WNT2b. Genomics 2021; 113:3512-3522. [PMID: 34284078 DOI: 10.1016/j.ygeno.2021.07.018] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 05/31/2021] [Accepted: 07/14/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Our study aims to identify the impact of histone deacetylase 3 (HDAC3) and microRNA-376c-3p (miR-376c-3p) on gastric cancer (GC) by targeting wingless-type MMTV integration site family member 2b (WNT2b). METHODS Levels of miR-376c-3p, HDAC3 and WNT2b were assessed. GC cells were treated with altered HDAC3 or miR-376c-3p to evaluate their biological functions, and rescue experiment was performed to assess the effect of WNT2b on GC cells. The tumor growth in vivo was observed. RESULTS HDAC3 and WNT2b were up-regulated while miR-376c-3p was reduced in GC tissues and cell lines. The inhibited HDAC3 or elevated miR-376c-3p could restrain malignant behaviors of GC cells in vitro, and also suppress the xenograft growth. WNT2b silencing reduced the effect of miR-376c-3p inhibition while WNT2b overexpression mitigated that of miR-376c-3p promotion on GC cell growth. CONCLUSION Inhibiting HDAC3 promotes miR-376c-3p to suppress malignant phenotypes of GC cells via reducing WNT2b, thereby restricting GC development.

Abstract
Gastric cancer has a high morbidity and mortality. Chemotherapy regimens are routine advanced stage gastric cancer (AGC) treatment protocols, but most of these drugs have side-effects such as myelosuppression and gastrointestinal disorders. Cinobufacini, an extractive from TCM, could suppress cell proliferation and inhibit gastric cancer. In this study, we comprehensively reviewed the literature on the efficacy comparison between Cinobufacini injection combined with chemotherapy and chemotherapy solely used in AGC treatment. We extracted data for from six electronic databases to evaluate the efficacy of Cinobufacini injection on AGC patients. Twelve studies with a total of 853 patients were finally included in our study. The results indicated that Cinobufacini injection could increase response rate and disease control rate of chemotherapy on AGC, improve the life quality of AGC patients, increase leukocytes, improve anemia, improve hand-foot syndrome induced by chemotherapy, and relieve cancer pain. This study has its own limitations that prevented us from drawing a definite conclusion and more well-designed clinical trials of TCM are needed.

JOURNAL OF ETHNOPHARMACOLOGY 2018; 213:359-365.

Abstract
Alocasia cucullata, a Chinese herb, has been used as an anticancer treatment in southern China. Phosphatase and tensin (PTEN), is a tumor suppressor gene and the loss of PTEN expression may activate the phosphoinositide-3-kinase (PI3K)/AKT signaling pathway which play a key role in tumors formation and progression. In this study, we evaluated the anti-melanoma effect and the underlying mechanism of 50% ethanolic extract of A. cucullata (EAC) in vitro and in vivo. Using MTT, wound healing, and transwell assays, we found that EAC suppressed the proliferation, migration, and invasion of melanoma cells (B16-F10, A375 and A2058) in a dose-dependent manner. We also found that EAC suppresses B16-F10 tumor growth in a xenografted mouse model. Western blot analysis revealed that the expression level of PTEN was up-regulated, and phosphorylation of PI3K and AKT reduced in B16-F10 cells and tumor tissues after EAC treatment. No significant differences were observed in PI3K and AKT expression. Moreover, immunohistochemistry showed that the number of PTEN-positive cells in tumor tissues increased and that of p-AKT-positive cells decreased with EAC treatment, corroborating the western blot results. Our data reveal that EAC can inhibit malignant melanoma in vitro and in vivo and suggest that its anti-tumor effect is associated with modulation of the PTEN/ PI3K/AKT signaling pathway. In summary, our findings highlight a promising herbal remedy for the treatment of malignant melanoma, which warrants further study.

Abstract
Pachymic acid (PA), a lanostane-type triterpenoid derived from traditional Chinese herbals, has been reported to have antitumor activity in versatile cancer cells. However, the antitumor effect of PA in gastric cancer (GC) cells remains unclear. In this study, we aimed to explore the efficacy and mechanisms of PA in GC. The antiproliferative effect of PA was assessed by a growth assay and a colony formation assay. Flow cytometry was used to detect changes in cell cycle distribution. Apoptosis was assessed by an annexin V/propidium iodide double-staining assay. The expressions of the apoptosis-related proteins were measured by western blot. The mitochondrial capacity was observed by immunostaining of Mito Tracker Red and mitochondrial function protein MT. Xenograft models of GC were constructed by a subcutaneous injection of SGC-7901 and MKN-49P cells pretreated with PA. PA could potently inhibit GC cell growth and colony formation. PA significantly induced G1, G2/M, and inhibited G0 phase arrest in GC cell lines SGC-7901 and MKN-49P. PA induced cell apoptosis by regulating the expressions of apoptosis-related proteins (caspase-3, PARP, Bcl-2, and Bax) and suppressing the mitochondrial capacity of GC cell lines in vitro in a dose-dependent manner. In addition, PA suppressed the tumor growth of xenograft models of GC and prolonged the survival of animals markedly. In brief, the present study shows that PA induces apoptosis through inhibition of mitochondrial capacity in human GC cells. Our findings suggest that PA may have therapeutic potential in GC.

Abstract
Background: The plant Ecballium elaterium (L.) A. Rich, belongs to the Cucurbitaceae family which occupies an important position in traditional medicine prescriptions. It has been reported that a freeze-dried aqueous extract of E. elaterium fruits has cytotoxic effects on the AGS human stomach adenocarcinoma cell line. We here focused on anticancer effects of the main chemicals purified from E. elaterium fruits. Materials and Methods: We isolated cucurbitacins D, E, and I from chloroform, and ethyl acetate fractions of a methanolic extract of E. elaterium fruits and assessed their cytotoxic effects on the AGS cell line by MTT assay. The methanolic extract was fractionated to petroleum ether, chloroform, and ethyl acetate fractions. The compounds isolated by column chromatography were identified by NMR spectroscopy. Results: After 24 h of incubation with AGS cells, the IC50 values were 0.3, 0.1, and 0.5 μg/ml for cucurbitacins D, E, and I respectively. Conclusions: This finding suggests that because of its cucurbitacins, E. elaterium fruit may have some cytotoxic effects on gastric cancer cells. Also, compared with D and I, cucurbitacin E showed greater potency in this regard.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shen-Ling-Bai-Zhu Powder (SLBZP) is a classic traditional Chinese medical formula that has been used for several decades in the treatment of patients with gastrointestinal malignancies. Whether SLBZP is best employed as single agent or adjunctive therapy has yet to be determined as does the mechanism whereby SLBZP exerts its anti-tumor effects. AIM OF THE STUDY To investigate the effects of SLBZP alone and in combination with Cytoxan (CTX) on tumor growth, malignant cell apoptosis and Akt/Nuclear Factor kappa B (NF-КB) signaling in a murine model of hepatocellular carcinoma (HCC) receiving chemotherapy. MATERIALS AND METHODS Sixty-four adult mice developed HCC following subcutaneous inoculation with H22 hepatocellular carcinoma cells. Seven days later, all received chemotherapy with CTX (200mg/kg) once. Mice were then randomized into eight study groups (N=8/group). Three groups were treated with different concentrations of SLBZP alone (6.00, 3.00, 1.5g/kg), three with SLBZP (6.00, 3.00, 1.5g/kg) plus CTX (20mg/kg), one with CTX (20mg/kg) alone (positive control), and one with physiologic saline (untreated, negative control). All groups were treated for 14 days. Tumor size, histology and serum or tissue levels and/or mRNA expression of PDGF-BB, VEGF, Ang-1, Ang-2, NF-КB, B-cell lymphoma-2 (Bcl-2); B-cell lymphoma-extra large (Bcl-xL); X-linked inhibitor of apoptosis (XIAP), Survivin, Caspase-3, Caspase-9, Caspase-7, Akt and phosphorylated Akt expression were documented at the end of treatment. RESULTS Compared to untreated negative controls, tumor sizes were decreased in the CTX alone, SLBZP (M)+CTX and SLBZP (H)+CTX groups (-52%,-53% and -58% respectively). Tumor cell density was decreased in all treated groups but most apparent in the SLBZP (H)+CTX group. Electron microscopic evidence of apoptosis was also most apparent in this group. Serum and/or tissue levels and expression of PDGF-BB, VEGF, Ang-1, Ang-2, their downstream signaling proteins and anti-apoptotic markers were lowest and pro-apoptotic markers highest in SLBZP (H)+CTX treated mice. CONCLUSIONS In this chemotherapy-induced animal model of HCC, SLBZP was most efficacious as adjunctive therapy and appears to act by inhibiting tumor growth promoters and anti-apoptotic proteins while enhancing pro-apoptotic proteins.

Abstract
Three polyphenols were isolated and purified from sugar beet molasses by ultrasonic-aid extraction and various chromatographic techniques, and their structures were elucidated by spectral analysis. Cytotoxicity and the molecular mechanism were measured by methyl thiazolyl tetrazolium (MTT) assay, flow cytometry, caspase-3 activity assay and Western blot assay. The results showed that gallic acid, cyanidin-3-O-glucoside chloride and epicatechin have cytotoxicity to the human colon, hepatocellular and breast cancer cells. Cyanidin-3-O-glucoside chloride showed its cytotoxicity against various tumor cell lines, particularly against colon cancer Caco-2 cells with half maximal inhibitory concentration (IC50) value of 23.21 ± 0.14 μg/mL in vitro. Cyanidin-3-O-glucoside chloride may be a potential candidate for the treatment of colon cancer. In the mechanism study, cyanidin-3-O-glucoside chloride increased the ratio of cell cycle at G0/G1 phase and reduced cyclin D1 expression on Caco-2 cells. Cyanidin-3-O-glucoside chloride decreased mutant p21 expression, and increased the ratio of Bax/Bcl-2 and the activation of caspase-3 to induce apoptosis.

Abstract
Polyethylenimine (PEI) was conjugated to oleic acid (PEI-OA) and evaluated as a delivery agent for LOR-2501, an antisense oligonucleotide against ribonucleotide reductase R1 subunit. PEI-OA/LOR-2501 complexes were further coated with folic acid (FA/PEI-OA/LOR-2501) and evaluated in tumor cells. The level of cellular uptake of FA/PEI-OA/LOR-2501 was more than double that of PEI/LOR-2501 complexes, and was not affected by the expression level of folate receptor (FR) on the cell surface. Efficient delivery was seen in several cell lines. Furthermore, pathway specific cellular internalization inhibitors and markers were used to reveal the principal mechanism of cellular uptake. FA/PEI-OA/LOR-2501 significantly induced the downregulation of R1 mRNA and R1 protein. This novel formulation of FA/PEI-OA provides a reliable and highly efficient method for delivery of oligonucleotide and warrants further investigation.

Cui GH, Li WX, Lin ZY, Zhang WQ, Hu ZH, Wang L. Short interfering RNA directed against the GOLPH3 gene enhances the effect of chemotherapy against oral squamous cell carcinoma by regulating Caspase3, Bcl2 and cytochrome-c expression. Int J Clin Exp Med 2015; 8:13007-13012. [PMID: 26550222 PMCID: PMC4612907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2015] [Accepted: 08/11/2015] [Indexed: 06/05/2023]
Abstract
Growing evidence reported that Golgi phosphoprotein 3 (GOLPH3) was involved in the progression of several human cancers. To determine whether knockout of GOLPH3 enhances the effect of Chemotherapy against cell growth of oral squamous cell carcinoma in vitro. OSCC cells were transfected with Golph3 plasmid, Golph3-RNAi and the relative control plasmids. Transfected Tca-8113 cells treated with cis-Dichlorodiamineplatinum (DDP; 0, 0.05, 0.25, 1.25, 6.25 and 31.25 ug/ml) or Paclitaxe (0, 2, 10, 50, 250 and 1250 nM) or Adriamycin (0, 0.25, 0.5, 1, 2 and 4 ug/ml) for 24 h, respectively, was determined using MTT assay. Apoptosis-related protein expression Cytochrome-C, Caspase3 and Bcl-2 was analyzed by RT-PCR and western blots. Result of MTT showed that Golph3-RNAi transfected Tca-8113 cells enhanced the effect of chemotherapy, and the effect was strengthened with the increasing concentration of drugs, and the Golph3 plasmid transfected Tca-8113 cells showed the opposite effect. RT-PCR and western blots assays revealed that expression of cytochrome-C and caspase3 were up-regulated, while Bcl-2 expression was down-regulated in Golph3-RNAi transfected Tca-8113 cells. Taken together, this study demonstrated that GOLPH3 had potent pro-tumor growth and decreased the effect of Chemotherapy, and its mechanism is primarily via cell anti-apoptosis, down-regulating the expression of cytochrome-C and caspase3, up-regulating Bcl-2 expression.
