Natural product mitigation of ferroptosis in platinum-based chemotherapy toxicity: targeting the underpinning oxidative signaling pathways
Platinum-based anticancer chemotherapy (PAC) represents a cornerstone in cancer treatment, retaining its status as the gold standard therapy. However, PAC's efficacy is countered by significant toxicities, such as nephrotoxicity, ototoxicity, and neurotoxicity. Recent studies have linked these toxicities to ferroptosis, characterized by iron accumulation, reactive oxygen species generation, and lipid peroxidation. This review explores the mechanisms underlying PAC-induced toxicities, focusing on the involvement of ferroptosis with three major PAC drugs-cisplatin, carboplatin, and oxaliplatin. Further, we provide a comprehensive analysis of the natural product mitigation of PAC-induced ferroptotic toxicity.

Psidium guajava leaves extract alters colonic microbiome composition and reduces intestinal sodium absorption in rats exposed to a high-sodium diet
High sodium intake is a major risk factor for hypertension and renal diseases. Previous studies have shown that a suspension of ethanolic extract of Psidium guajava (guava) leaves (PsE) has antihypertensive effects in rats on a high-sodium diet (HSD), but some mechanisms to that remain unexplored. This study explored whether oral PsE treatment affects sodium handling by the intestine and alters the gut microbiome in HSD-fed rats.

Mechanism of traditional drug treatment of cancer-related ascites: through the regulation of IL-6/JAK-STAT3 pathway
Our clinical observation found that JiJiaoLiHuang Pill (JJLH), a classic traditional Chinese medicine (TCM) formulation, can significantly reduce the abdominal circumference of patients with malignant ascites, increase urine output, and improve the quality of life of patients, with preliminary efficacy. But, the exact mechanism is not yet clear.
The regulatory effects of mitragynine on P-glycoprotein transporter
Kratom preparation containing Mitragyna speciosa Korth plant is frequently used as a recreational drug. Mitragynine, a major alkaloid isolated from M. speciosa, is often detected concurrently with other drugs during forensic analysis, indicating a safety concern. P-glycoprotein (P-gp) is a multidrug transporter. Modulation of P-gp transport activity by drugs or herbal compounds in the brain may lead to drug-herb interactions, resulting in neurotoxicity. We aim to determine the effects of mitragynine on the P-gp regulation and possible neurotoxicity.
Protein phosphatase 2A inhibitors: a possible pharmacotherapy for benzodiazepine dependence
Benzodiazepines (BZDs) activate the γ-aminobutyric acid (GABA) subtype A (GABAA) receptors, and thus are widely used medicines for the treatment of anxiety and insomnia. For chronic use, tolerance to BZDs is a major problem. Patients with chronic insomnia that develop tolerance to BZDs lose therapeutic effects but also potentially suffer from BZD dependence resulting in BZD withdrawal. The development of such treatments is important for the appropriate use of BZDs.
Silencing c-myc gene by siRNA delivered by cationic niosomes in MCF-7 cells
Gene therapy has a strong potential to treat different cancer types cancers with high therapeutic outcomes. c-myc is believed to be responsible for more than 15% of all gene regulation and functions as a transcription factor for proteins essential for cell proliferation. This study aimed to develop niosome nanocarriers to knockdown c-myc expression using anti-c-myc short-interfering RNA (siRNA) in MCF-7 cells. Altering the activity of the c-myc proto-oncogene has been identified as an important element in minimizing cancer cell growth because anti-c-myc siRNA degrades c-myc mRNA.
DST regulates cisplatin resistance in colorectal cancer via PI3K/Akt pathway
Dystonin (DST), a potential tumor suppressor gene, plays a crucial role in regulating cancer cell proliferation and resistance to chemotherapy. However, DST's specific role in colorectal cancer (CRC) has not been thoroughly investigated, and this study aims to elucidate its molecular role in modulating cisplatin (DDP) resistance in CRC.
Molecular mechanisms of endoplasmic reticulum stress-mediated acute kidney injury in juvenile rats and the protective role of mesencephalic astrocyte-derived neurotrophic factor
This study examined the role of endoplasmic reticulum stress in pediatric acute kidney injury and the therapeutic effect of midbrain astrocyte-derived neurotrophic factor.
Alleviating vascular calcification with Bushen Huoxue formula in rats with chronic kidney disease by inhibiting the PTEN/PI3K/AKT signaling pathway through exosomal microRNA-32
Vascular calcification (VC) significantly raises cardiovascular mortality in chronic kidney disease (CKD) patients. VC is characterized by the phenotypic transformation of vascular smooth muscle cells (VSMCs) to osteoblast-like cells, mediated by exosomes derived from calcified VSMCs and the exosomal microRNAs (miRNA) which may trigger some signals to recipient VSMCs. Bushen Huoxue (BSHX) formula has demonstrated its clinical efficacy in CKD and its protective role in CKD-VC rats has also been observed. However, little is known about its underlying mechanism.
