Ultra-diluted/dynamized doxorubicin reduces the toxicity caused by doxorubicin during the in vitro culture of pig preantral follicles enclosed in ovarian tissue. Reprod Toxicol 2024; 129:108683. [PMID: 39121978 DOI: 10.1016/j.reprotox.2024.108683] [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: 12/07/2023] [Revised: 08/02/2024] [Accepted: 08/06/2024] [Indexed: 08/12/2024]
Abstract
The present study investigated the effect of adding allopathic doxorubicin (DOX 0.3 µg/mL), the vehicle of ultradiluted/dynamized doxorubicin (0.2 % ethanol), different dynamizations of ultradiluted/dynamized doxorubicin (DOX 6CH, DOX 12CH and DOX 30CH), both in the absence or presence of chemical stress induced by doxorubicin at 0.3 µg/mL on follicular survival and activation, antioxidant capacity of the medium, Catalase activity (CAT), production of reactive protein thiol, maintenance of type I and III collagen fibers and accumulation of lipofuscin in porcine ovarian tissue cultured in vitro for 48 hours. To do this, part of the ovarian tissue fragments was fixed for the uncultured control and the rest were cultured in: MEM (cultured control), DOX 0.3 µg/mL, Ethanol, DOX 6CH, DOX 12CH, DOX 30CH, DOX (0.3 µg/mL) + DOX 6CH, DOX (0.3 µg/mL) + DOX 12CH, DOX (0.3 µg/mL) + DOX 30CH treatments. The results showed that, in general, ultradiluted/dynamized doxorubicin (DOX 6CH, DOX 12CH and DOX 30CH) mitigated the toxic effect of allopathic doxorubicin (0.3 µg/mL) on the morphology of preantral follicles, the content of type I and III collagen fibers, and the production of lipofuscin in the tissue. However, only DOX (0.3 µg/mL) + DOX 6CH attenuated the oxidative stress induced by DOX (0.3 µg/mL), maintaining adequate CAT activity that was similar to the uncultured control. Additionally, when the three isolated ultradiluted/dynamized doxorubicin were considered, only DOX 12CH increased the reduced thiol levels compared to the uncultured control and MEM. In conclusion, supplementing the culture medium with ultradiluted/dynamized DOX (DOX 6CH, DOX 12CH and DOX 30CH) attenuated the toxicity induced by allopathic doxorubicin during the in vitro culture of pig preantral follicles enclosed in ovarian tissue.

Abstract
BACKGROUND Complementary and alternative medicine, including homeopathy, is widely used to improve well-being among cancer patients and reduce adverse effects of conventional treatment. In contrast, there are few studies on the use of homeopathic medicines to treat the disease itself. Yet, evidence of possible effectiveness of homeopathic high dilutions in experimental cancer models has been published during the past 20 years. AIM The aim of the study was to perform a systematic review of fundamental research studies on homeopathic high dilutions in cancer. METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, we conducted a literature search in the database PubMed for original publications, from 2000 to 2018 and in English, on in vitro and in vivo experimental cancer models testing homeopathic high dilutions. RESULTS Twenty-three articles met the inclusion criteria-14 in vitro, eight in vivo, and one in vitro plus in vivo experimental models. Most studies were from India. Research prominently focused on cytotoxic effects involving apoptotic mechanisms. Intrinsic aspects of homeopathy should be considered in experimental designs to emphasize the specificity of such effects. CONCLUSION Fundamental research of homeopathy in cancer is still at an early stage and has mainly been performed by a few groups of investigators. The results point to an interference of well-selected homeopathic medicines with cell cycle and apoptotic mechanisms in cancer cells. However, these findings still need independent reproduction.

Abstract
Ethanol is used routinely to dilute cell culture media supplements with little or no water solubility. This study evaluates the effect of low concentration of ethanol on the follicular development, oocyte maturation, hormone production, gene expression, and metabolomics profile of spent culture medium after long-term culture of isolated ovine preantral follicles. For this, follicles were cultured for 18 days in α-Minimum Essential Medium+ alone (control treatment) or supplemented with 100 ng/mL recombinant bovine FSH (rbFSH treatment) or with 0.2%-v/v ethanol (ethanol treatment). Ethanol treatment increased the percentage of degenerated follicles and oocytes significantly, however, it showed the highest estradiol secretion. Also, the rate of meiosis resumption was higher in ethanol treatment than Control treatment. Ethanol treatment decreased the mRNA levels of B-cell lymphoma 2 (BCL2), BCL2 associated X, Aquaporin 3, Connexin 43, Inhibin Subunit Beta A, kit ligand, Heat Shock Protein (HSP A1A) significantly when compared to the Control treatment. However, mRNA levels of cytochrome P450 family 19, and FSH receptors were significantly higher in ethanol treatment than in the Control treatment. The levels of some metabolites, which are likely amino acids, lipids, an analog of Cyclic guanosine monophosphate, and a derivative of phosphoinositol phosphate metabolism, had higher relative concentrations in ethanol and rbFSH treatments than the Control treatment. In conclusion, ethanol addition augmented the follicular and oocyte degeneration rates but increased the estradiol production and the meiotic resumption. Furthermore, the follicular metabolomic profile was similar between ethanol and rbFSH treatments being both treatments; however, different from the Control treatment.

Abstract
During the reproductive lifespan of a female, only a limited quantity of oocytes are naturally ovulated; therefore, the mammalian ovary possesses a substantial population of preantral follicles available to be handled and explored in vitro. Hence, the manipulation of preantral follicles enclosed in ovarian tissue aims to recover a considerable population of oocytes of high-value animals for potential application in profitable assisted reproductive technologies (ARTs). For this purpose, the technique of preantral follicle in vitro culture (IVC) has been the most common research tool, achieving extraordinary results with offspring production in the mouse model. Although promising outcomes have been generated in livestock animals after IVC of preantral follicles, the quantity and quality of embryo production with those oocytes are still poor. In recent years, the mare has become an additional model for IVC studies due to remarkable similarities with women and livestock animals regarding in vivo and in vitro ovarian folliculogenesis. For a successful IVC system, several factors should be carefully considered to provide an optimum culture environment able to support the viability and growth of preantral follicles enclosed in ovarian tissue. The cryopreservation of the ovarian tissue is another important in vitro manipulation technique that has been used to preserve the reproductive potential in humans and, in the future, may be used in highly valuable domestic animals or endangered species. Several improvements in cryopreservation protocols are necessary to support the utilization of ovarian tissue of different species in follow-up ARTs (e.g., ovarian fragment transplantation). This review aims to provide an update on the most current advances regarding supportive in vitro techniques used in equids to evaluate and manipulate preantral follicles and ovarian tissue, as well as methodological approaches used during IVC and cryopreservation techniques.

Abstract
Metastasis is responsible for the majority of deaths among patients with malignant melanoma. Despite recent advances, the majority of current and modern therapies are ineffective and/or financially unfeasible. Thus, in this study, we investigated two low‑cost highly‑diluted natural complexes (HDNCs) that have been shown to be effective against malignant melanoma in a murine model in vivo. The aim of this study was to determine the mechanisms through which these HDNCs directly affect melanoma cells, either alone or in an artificial tumor microenvironment, suppressing the metastatic phenotype, thus explaining previous in vivo effects. For this purpose, HDNC in vitro treatments of B16‑F10 melanoma cells, alone or in co‑culture with Balb/3T3 fibroblasts, were carried out. Molecular biology techniques and standard functional assays were used to assess the changes in molecule expression and in cell behaviors related to the metastatic phenotype. Melanoma progression features were found to be regulated by HDNCs. Molecules related to cell adhesion (N‑cadherin, β1‑integrin and CD44), and migration, extracellular matrix remodeling and angiogenesis were modulated. The cell migratory, invasive and clonogenic capacities were reduced by the HDNCs. No loss of cell proliferation or viability were observed. On the whole, the findings of this study indicate that HDNCs directly reprogram, molecularly and functionally, melanoma cells in vitro, modulating their metastatic phenotype. Such findings are likely to be responsible for the attenuation of tumor growth and lung colonization previously observed in vivo.

Abstract
The objective of this study was to determine whether preantral follicles cultured in vitro for 7 days within ovine ovarian cortical strips could be isolated at the secondary follicles (SF) and grown until antral stage during an additional 6 days period of in vitro culture in the presence of aqueous extract of Justicia insularis. Fresh ovarian fragments from 16 adult sheep were fixed for histological analysis (Control 1) or in vitro cultured individually in α-MEM+ supplemented with 0.3 mg/ml J. insularis (Step 1) for 7 days. Part of the fragments then were fixed for histological analysis (in vitro culture group). Remaining fragments were exposed stepwise to increasing trehalose concentrations before immediate isolation of SF and viability assessment (Control 2) or after 6 days of culture in α-MEM++ supplemented with 0.3 mg/ml J. insularis (Step 2). In Step 1, percentage of follicular activation was 80%. In Step 2, a significant increase (p < 0.05) in follicular diameter and antrum formation within 6 days in vitro culture of isolated follicles was achieved. The total antioxidant capacity from both steps significantly increase (p < 0.05) from day 2 to day 6. Confocal analysis of oocytes showed 57.14% oocytes with homogeneous distribution and 42.86% with peri-cortical distribution. In conclusion, SF can be successfully isolated from sheep ovarian cortex after 7 days of culture and are capable of surviving and forming an antral cavity if cultured in vitro for an additional 6 days in the presence of 0.3 mg/ml J. insularis.

Abstract
The present study evaluated the effect of supplementing in vitro culture medium with J. insularis compared to FSH on isolated secondary follicles and in vitro maturation of oocytes from those follicles. Secondary follicles were isolated from sheep ovaries and individually cultured for 18 days in α-MEM+ (Control), α-MEM+ supplemented with 100 ng/mL recombinant bovine follicle stimulating hormone (FSH) or with 0.3, 1.25, or 2.5 mg/mL of J. insularis extract (JI0.3, JI1.25, and JI2.5, respectively). Culture medium collected every 2 days was used to measure ROS levels. At the end of the culture period, cumulus oocytes complex (COCs) were collected and matured in vitro. Follicular walls were used for mRNA quantitation. JI0.3 led to a higher (P < 0.05) percentages of intact follicles than other groups after 18 days of culture. While follicular diameter remained unchanged from Day 6 onwards with JI0.3 and FSH, percentages of antral cavity formation were higher (P < 0.05) with JI0.3 at Day 6 than in all other treatments. No differences were observed between controls and treatment groups regarding ROS levels and mRNA expression of genes. Viability of resulting oocytes was higher (P < 0.05) in JI0.3 compared to FSH. Interestingly, in control experiment, supplementation of maturation medium with JI0.3 led to higher (P < 0.05) percentages of metaphase II compared to controls. Although more validations will be needed, it seems that this natural extract could be used as a cheap and easily available alternative to commercial FSH.
