Nanostructured biloalbuminosomes loaded with berberine and berberrubine for Alleviating heavy Metal-Induced male infertility in rats

Despite the remarkable biological effects of berberine (BBR), particularly on fertility, its bioavailability is low. This study aims to test the effectiveness of novel nanostructured biloalbuminosomes (BILS) of BBR and its metabolite berberrubine (M1) in treatment of testicular and prostatic lesions. M1 was semi-synthesized from BBR using microwave-assisted reaction. The solvent evaporation method was used to prepare BBR-BILS and M1-BILS by three different concentrations of sodium cholate (SC) or glycocholate (SG), along with the incorporation of bovine serum albumin (BSA). The prepared BILS were fully characterized. Male infertility was induced by cadmium (Cd) at 5 mg/kg and lead (Pb) at 20 mg/kg contaminated water for 90 days, followed by treatment with BBR, M1, and their BILS (BBR-BILS and M1-BILS) for 45 days. Blood male infertility markers, testicular and prostatic oxidative stress status, autophagy, inflammation, along with testicular and prostatic concentrations of Cd and Pb, and histopathology of both tested tissues were determined using standardized protocols. The optimal BBR-BILS and M1-BILS nano-preparations, containing 30 mg SC, were chosen based on the best characterization properties of the preparations. Both nano-preparations improved heavy metals-induced testicular and prostatic deformities, as they reduced Bax and elevated Bcl-2 expressions in both tissues. Moreover, they activated the mTOR/PI3K pathway with a marked reduction in AMPK and activated LC-3II protein levels. Consequently, testicular and prostatic architecture and functions were improved. This study is the first to report the preparation of BBR and M1 BILS nano-preparations and proved their superior efficacy compared to free drugs against testicular and prostatic deformities by attenuating oxidative stress-induced excessive autophagy, offering a new hope to manage male infertility.

Evodiamine exerts anti-cancer activity including growth inhibition, cell cycle arrest, and apoptosis induction in human follicular thyroid cancers

Thyroid cancer (TC) is one of the most prevalent endocrine malignancy with a steadily increasing incidence globally. Although standard treatments like thyroidectomy and radioiodine therapy effectively manage most cases of differentiated thyroid cancers (DTC), certain recurrent cases or those involving poorly differentiated thyroid cancers (PDTC) demand more specialized interventions. Follicular thyroid cancer (FTC) is the second most common type of DTC, and frequently metastasizes through the bloodstream to distant sites such as bones and lungs which is a leading cause of metastatic and recurrent DTC and significantly affects survival. However, existing drugs primarily address symptom management without offering a curative solution. Therefore, it is urgent to develop a new therapeutic agent for these challenging cases. Evodiamine (EVO), extracted from Evodia rutaecarpa, has shown potential as an anti-cancer agent in multiple types of human cancers including anaplastic thyroid cancer (ATC) and papillary thyroid cancer (PTC) cells. However, the anti-cancer effects of EVO on FTC have remained unclear. Therefore, the present study aims to investigate the anti-cancer effects of EVO in FTC cells. Our data showed that EVO effectively inhibits FTC cell growth, induces cell cycle arrest, and triggers apoptosis. Additionally, our study explored the underlying mechanisms through which EVO affects signaling pathways. To verify the anti-cancer effects of combination chemotherapy, EVO and doxorubicin were used together in FTC cells. In conclusion, this study demonstrates that EVO shows significant anti-human FTC activity, making it a promising therapeutic candidate for the treatment of follicular thyroid cancers.

Piperlongumine Induces Cellular Apoptosis and Autophagy via the ROS/Akt Signaling Pathway in Human Follicular Thyroid Cancer Cells

Thyroid cancer (TC) is the most common endocrine malignancy. Recently, the global incidence of TC has increased rapidly. Differentiated thyroid cancer includes papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC), which are the most common types of TC. Although PTCs and FTCs exert good prognoses and high survival rates, FTCs tend to be more aggressive than PTCs. There is an urgent need to improve patient outcomes by developing effective therapeutic agents for FTCs. Piperlongumine exerts anti-cancer effects in various human carcinomas, including human anaplastic TCs and PTCs. However, the anti-cancer effects of piperlongumine in FTCs and the underlying mechanisms are yet to be elucidated. Therefore, in the present study, we evaluated the effect of piperlongumine on cell proliferation, cell cycle, apoptosis, and autophagy in FTC cells with flowcytometry and Western blot. We observed that piperlongumine caused growth inhibition, cell cycle arrest, apoptosis induction, and autophagy elevation in FTC cells. Activities of reactive oxygen species and the downstream PI3K/Akt pathway were the underlying mechanisms involved in piperlongumine mediated anti-FTC effects. Advancements in our understanding of the effects of piperlongumine in FTC hold promise for the development of novel therapeutic strategies.

Berberine inhibits the growth of osteosarcoma through modulating MMP/NM-23 and MAPK/JNK signal pathways

OBJECTIVE

To investigate the effects and mechanisms of berberine (BBR) on the migration, invasion, proliferation and apoptosis of osteosarcoma cells in vitro.

METHODS

Proliferation of MG-63 and U2OS cells was measured by the CCK-8 assay. Cells migration was examined by wound-healing assay. The invasion and metastasis of cells were evaluated by transwell invasion assay. Cells apoptosis was determined by the flow cytometry. Caspase-3 activity in MG-63 and U2OS cells was measured, and Western blot was used to measure the levels of Bax, Bcl-2, MMP-2 and MMP-9 in cells. In addition, the osteosarcoma graft tumor model of mice was established. The tumorigenesis of MG-63 cells in nude mice was compared among three groups. Immunohistochemistry assay was used to measure the levels of MMP-2, MMP-9 and NM-23 in tumor tissue.

RESULTS

It was showed that BBR inhibited the proliferation of MG-63 and U2OS cells in vitro in time- and concentration-dependent manners. Moreover, BBR reduced the cells migration and invasion, also down-regulated the expressions of MMP-2 and MMP-9. BBR also inhibited the cells apoptosis by down-regulating the expression of Bcl-2 and up-regulating the expression of Bax. In nude mice, BBR obviously inhibited the tumorigenesis of MG-63 cells. Compared with the negative group, BBR decreased the levels of MMP-2 and MMP-9 and increased the level of NM-23. The molecular mechanism was associated with activation of the MAPK/JNK signal transduction pathway.

CONCLUSIONS

BBR significantly regulates the biological behaviors of osteosarcoma cells and inhibits the growth of osteosarcoma. The molecular mechanism may be associated with the modulation of MMP/NM-23 and MAPK/JNK signals. BBR may be a potential drug for the treatment of osteosarcoma.

Multi-Target Potential of Berberine as an Antineoplastic and Antimetastatic Agent: A Special Focus on Lung Cancer Treatment

Despite therapeutic advancements, lung cancer remains the principal cause of cancer mortality in a global scenario. The increased incidence of tumor reoccurrence and progression and the highly metastatic nature of lung cancer are of great concern and hence require the investigation of novel therapies and/or medications. Naturally occurring compounds from plants serve as important resources for novel drugs for cancer therapy. Amongst these phytochemicals, Berberine, an alkaloid, has been extensively explored as a potential natural anticancer therapeutic agent. Several studies have shown the effectiveness of Berberine in inhibiting cancer growth and progression mediated via several different mechanisms, which include cell cycle arrest, inducing cell death by apoptosis and autophagy, inhibiting cell proliferation and invasion, as well as regulating the expression of microRNA, telomerase activity, and the tumor microenvironment, which usually varies for different cancer types. In this review, we aim to provide a better understanding of molecular insights of Berberine and its various derivative-induced antiproliferative and antimetastatic effects against lung cancer. In conclusion, the Berberine imparts its anticancer efficacy against lung cancers via modulation of several signaling pathways involved in cancer cell viability and proliferation, as well as migration, invasion, and metastasis.

Berberine as a potential agent for breast cancer therapy

Breast cancer (BC) is a common malignancy that mainly occurred in women and it has become the most diagnosed cancer annually since 2020. Berberine (BBR), an alkaloid extracted from the Berberidacea family, has been found with broad pharmacological bioactivities including anti-inflammatory, anti-diabetic, anti-hypertensive, anti-obesity, antidepressant, and anticancer effects. Mounting evidence shows that BBR is a safe and effective agent with good anticancer activity against BC. However, its detailed underlying mechanism in BC treatment remains unclear. Here, we will provide the evidence for BBR in BC therapy and summarize its potential mechanisms. This review briefly introduces the source, metabolism, and biological function of BBR and emphasizes the therapeutic effects of BBR against BC via directly interacting with effector proteins, transcriptional regulatory elements, miRNA, and several BBR-mediated signaling pathways. Moreover, the novel BBR-based therapeutic strategies against BC improve biocompatibility and water solubility, and the efficacies of BBR are also briefly discussed. Finally, the status of BBR in BC treatment and future research directions is also prospected.

Apoptosis Induction, a Sharp Edge of Berberine to Exert Anti-Cancer Effects, Focus on Breast, Lung, and Liver Cancer

Cancer is the leading cause of death and one of the greatest barriers to increased life expectancy worldwide. Currently, chemotherapy with synthetic drugs remains one of the predominant ways for cancer treatment, which may lead to drug resistance and normal organ damage. Increasing researches have suggested that apoptosis, a type of programmed cell death, is a promising way for cancer therapy. Furthermore, natural products are important sources for finding new drugs with high availability, low cost and low toxicity. As a well-known isoquinoline alkaloid, accumulating evidence has revealed that berberine (BBR) exerts potential pro-apoptotic effects on multiple cancers, including breast, lung, liver, gastric, colorectal, pancreatic, and ovarian cancers. The related potential signal pathways are AMP-activated protein kinase, mitogen-activated protein kinase, and protein kinase B pathways. In this review, we provide a timely and comprehensive summary of the detailed molecular mechanisms of BBR in treating three types of cancer (breast, lung and liver cancer) by inducing apoptosis. Furthermore, we also discuss the existing challenges and strategies to improve BBR’s bioavailability. Hopefully, this review provides valuable information for the comprehension of BBR in treating three types of cancer and highlight the pro-apoptotic effects of BBR, which would be beneficial for the further development of this natural compound as an effective clinical drug for treating cancers.
