Colorectal cancer (CRC) is one of the deadliest neoplasia. Intrinsic or acquired resistance main cause failure therapy regimens that leads to relapse and death in CRC patients. The widely used chemotherapeutic agent 5-fluorouracil (5-FU) remains mainstay for therapeutic combinations. Unfortunately, side effects are frequent events compromise success these therapies; dysregulation enzymes regulate 5-FU metabolism increases expression activity efflux pumps. Additional tumor cell adaptations such as epithelial–mesenchymal transition (EMT), autophagy shaping microenvironment, inflammation contribute chemoresistance. Finding new strategies alternatives enhance conventional chemotherapies has become necessary. Recently, study natural compounds been gaining strength an alternative chemotherapeutics different cancers.

Colorectal cancer (CRC) is the third most diagnosed malignancy and a major leading cause of cancer-related deaths worldwide. Despite advances in therapeutic regimens, number patients presenting with metastatic CRC (mCRC) increasing due to resistance therapy, conferred by small population cells, known as stem cells. Targeted therapies have been highly successful prolonging overall survival mCRC. Agents are being developed target key molecules involved drug-resistance metastasis CRC, these include vascular endothelial growth factor, epidermal factor receptor, human receptor-2, mitogen-activated extracellular signal-regulated kinase, addition immune checkpoints. Currently, there several ongoing clinical trials newly targeted agents, which shown considerable efficacy improved prognosis who do not benefit from conventional chemotherapy. In this review, we highlight recent developments use existing novel agents against drug-resistant Furthermore, discuss limitations challenges associated therapy strategies combat intrinsic acquired therapies, importance implementing better preclinical models application personalized based on predictive biomarkers for treatment selection.

Abstract Background Gut microbiota modulation has been demonstrated to be effective in protecting patients against detrimental effects of anti-cancer therapies, as well improve the efficacy certain treatments. Among most characterized probiotics, Lactobacillus rhamnosus GG (LGG) is currently utilized clinics alleviate diarrhea, mucositis or intestinal damage which might associated with several triggers, including Clostridium difficile infections, inflammatory gut diseases, antibiotic consumption, chemotherapy radiation therapy. Here, we investigate whether LGG cell-free supernatant (LGG-SN) exert anti-proliferative activity toward colon cancer and metastatic melanoma cells. Moreover, assess potential adjuvant effect LGG-SN combination drugs. Methods alone either 5-Fuorouracil Irinotecan was used treat human cell lines. Dimethylimidazol-diphenyl tetrazolium bromide assay employed detect cellular viability. Trypan blue staining, anti-cleaved caspase-3 anti-total versus PARP western blots, annexin V/propidium iodide flow cytometry analyses were death.

Abstract Despite tremendous medical treatment successes, colorectal cancer (CRC) remains a leading cause of deaths worldwide. Chemotherapy as monotherapy can lead to significant side effects and chemoresistance that be linked several resistance-activating biological processes, including an increase in inflammation, cellular plasticity, multidrug resistance (MDR), inhibition the sentinel gene p53, apoptosis. As consequence, tumor cells escape effectiveness chemotherapeutic agents. This underscores need for cross-target therapeutic approaches are not only pharmacologically safe but also modulate multiple potent signaling pathways sensitize overcome standard drugs. In recent years, scientists have been searching natural compounds used chemosensitizers addition conventional medications synergistic CRC. Resveratrol, polyphenolic phytoalexin found various fruits vegetables such peanuts, berries, red grapes, is one most effective chemopreventive Abundant vitro vivo studies shown resveratrol, interaction with drugs, chemosensitizer CRC agents thus prevents drug by modulating pathways, transcription factors, epithelial-to-mesenchymal transition-plasticity, proliferation, metastasis, angiogenesis, cell cycle, The ability resveratrol modify subcellular may suppress plasticity reversal critical parameters understanding its anti-cancer effects. this review, we focus on chemosensitizing properties and, thus, potential importance additive ongoing treatments.

The utilization of nanostructured materials for several biomedical applications has tremendously increased over the last few decades owing to their nanosizes, porosity, large surface area, sensitivity, and efficiency as drug delivery systems. Thus, incorporation functionalized pristine nanostructures cancer therapy offers substantial prospects curb persistent problems ineffective administration target sites. potential (Ca12O12) formyl (-CHO)- amino (-NH2)-functionalized (Ca12O12-CHO Ca12O12-NH2) derivatives efficient nanocarriers 5-fluorouracil (5FU) was studied at B3LYP-GD3(BJ)/6-311++G(d,p) theoretical level in two electronic media (gas solvent). To effectively account all adsorption interactions on investigated surfaces, studies well topological analysis based quantum theory atoms molecules (QTAIM) noncovalent were exhaustively utilized. Interestingly, obtained results divulged that 5FU interacted favorably with both Ca12O12 its derivatives. energies calculated be -133.4, -96.9, -175.6 kcal/mol, respectively, Ca12O12, Ca12O12-CHO, Ca12O12-NH2. Also, NBO stabilization revealed presence among O3-H32, O27-C24, O10-C27, N24-H32 surface. However, 5FU@Ca12O12-CHO portrayed least energy due considerable destabilization molecular complex by computed deformation energy. Therefore, 5FU@Ca12O12 5FU@Ca12O12-NH2 acted better nanovehicles 5FU.

Abstract Acquired drug resistance is one of the most common limitations for clinical response colon cancer to 5-Fluorouracil (5-FU)-based chemotherapy. The relevant molecular mechanisms might be diversity, but still not elucidated clearly. In this study, we aimed investigate potential c-Fos, a subfamily activator protein-1, in 5-FU chemoresistance. We determined that phosphorylated c-Fos promoted cells by facilitating stemness. Mechanically, treatment induced autolysosome-dependent degradation TMPO, which subsequently triggered ERK-mediated phosphorylation c-Fos. Additionally, was found bind promoter NANOG and at Ser 374 required its regulation expression. ablation impaired c-Fos/p-c-Fos Taken together, these findings revealed TMPO-mediated conferred regulating expression promoting cell stemness cells. could as therapeutic target cancer.

Gastric cancer (GC) is a prevalent gastrointestinal tumor characterized by high mortality and recurrence rates. Current treatments often have limitations, prompting researchers to explore novel anti-tumor substances develop new drugs. Flavonoids, natural compounds with diverse biological activities, are gaining increasing attention in this regard. We searched from PubMed, Web of Science, SpringerLink other databases find the relevant literature last two decades. Using "gastric cancer", "stomach cancers", "flavonoid", "bioflavonoid", "2-Phenyl-Chromene" as keywords, were searched, then analyzed summarized mechanism flavonoids treatment GC. It was revealed that involves inhibiting growth, proliferation, invasion, metastasis, well inducing cell death through various processes such apoptosis, autophagy, ferroptosis, pyroptosis. Additionally, combining chemotherapeutic agents like 5-FU platinum can potentially reduce chemoresistance. Flavonoids also demonstrated enhanced activity when used combination products. Consequently, review proposes innovative perspectives for development anti-GC agents.
