Abstract
In recent years, progress in nanotechnology provided new tools to treat cancer more effectively. Advances in biomaterials tailored for drug delivery have the potential to overcome the limited selectivity and side effects frequently associated with traditional therapeutic agents. While autophagy is pivotal in determining cell fate and adaptation to different challenges, and despite the fact that it is frequently dysregulated in cancer, antitumor therapeutic strategies leveraging on or targeting this process are scarce. This is due to many reasons, including the very contextual effects of autophagy in cancer, low bioavailability and non-targeted delivery of existing autophagy modulatory compounds. Conjugating the versatile characteristics of nanoparticles with autophagy modulators may render these drugs safer and more effective for cancer treatment. Here, we review current standing questions on the biology of autophagy in tumor progression, and precursory studies and the state-of-the-art in harnessing nanomaterials science to enhance the specificity and therapeutic potential of autophagy modulators.

Pharmacological impact of microRNAs in head and neck squamous cell carcinoma: Prevailing insights on molecular pathways, diagnosis, and nanomedicine treatment. Front Pharmacol 2023; 14:1174330.

Abstract
Head and neck squamous cell carcinoma is a disease that most commonly produce tumours from the lining of the epithelial cells of the lips, larynx, nasopharynx, mouth, or oro-pharynx. It is one of the most deadly forms of cancer. About one to two percent of all neo-plasm-related deaths are attributed to head and neck squamous cell carcinoma, which is responsible for about six percent of all cancers. MicroRNAs play a critical role in cell proliferation, differentiation, tumorigenesis, stress response, triggering apoptosis, and other physiological process. MicroRNAs regulate gene expression and provide new diagnostic, prognostic, and therapeutic options for head and neck squamous cell carcinoma. In this work, the role of molecular signaling pathways related to head and neck squamous cell carcinoma is emphasized. We also provide an overview of MicroRNA downregulation and overexpression and its role as a diagnostic and prognostic marker in head and neck squamous cell carcinoma. In recent years, MicroRNA nano-based therapies for head and neck squamous cell carcinoma have been explored. In addition, nanotechnology-based alternatives have been discussed as a promising strategy in exploring therapeutic paradigms aimed at improving the efficacy of conventional cytotoxic chemotherapeutic agents against head and neck squamous cell carcinoma and attenuating their cytotoxicity. This article also provides information on ongoing and recently completed clinical trials for therapies based on nanotechnology.

Abstract
Nanomaterials (NMs) have increasingly been used for the diagnosis and treatment of head and neck cancers (HNCs) over the past decade. HNCs can easily infiltrate surrounding tissues and form distant metastases, meaning that most patients with HNC are diagnosed at an advanced stage and often have a poor prognosis. Since NMs can be used to deliver various agents, including imaging agents, drugs, genes, vaccines, radiosensitisers, and photosensitisers, they play a crucial role in the development of novel technologies for the diagnosis and treatment of HNCs. Indeed, NMs have been reported to enhance delivery efficiency and improve the prognosis of patients with HNC by allowing targeted delivery, controlled release, responses to stimuli, and the delivery of multiple agents. In this review, we consider recent advances in NMs that could be used to improve the diagnosis, treatment, and prognosis of patients with HNC and the potential for future research.

Abstract
Congo red (CR) type self–assembled ribbon–like structures (SRLS) were previously shown to interact with some proteins, including albumin. SRLS also complex with some drugs with a flat, ring–shaped structure with aromatic characteristics, intercalating them into their ribbon structure. The combination of interaction with proteins and drug binding by SRLS enables the use of such systems for immunotargeting. It is especially interesting in the case of chemotherapeutic agents. The present experiments aimed to show that the model carrier system composed of supramolecular albumin and Congo red efficiently binds doxorubicin (Dox) and that the drug can be released at reduced pH. The presented results come from the studies on such complexes differing in the molar ratio of CR to Dox. The following methods were used for the analysis: electrophoresis, dialysis, gel filtration, spectral analysis, and analysis of the size of the hydrodynamic radius using the dynamic light scattering method (DLS). The applied methods confirmed the formation of the CR–Dox complex, with large dimensions and changed properties compared with free CR. The presented results show that albumin binds both CR and its complex with Dox. Various CR–Dox molar ratios, 5:1, 2:1, and 1:1, were analyzed. The confirmation of the possibility of releasing the drug from the carriers thus formed was also obtained. The presented research is important due to the search for optimal solutions for the use of SRLS in drug immunotargeting, with particular emphasis on chemotherapeutic agents.

Abstract
Phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) signaling pathway is one of the major cellular signaling pathways that plays an important role in basic intracellular functions. The PI3K/Akt/mTOR pathway regulates cell proliferation, growth, cell size, metabolism, and motility. Component genes of this pathway have been extensively studied and found to be commonly activated in human cancer. Inhibition of this pathway has been shown to lead to regression of human tumors and has been studied in preclinical setup and evaluated in many clinical trials at various levels. Some inhibitors of this pathway are approved by the Food and Drug Administration after their potency and safety have been shown in clinical trials. This review discusses the recent trends in exploiting the PI3K/Akt/mTOR pathway towards the molecular targeted therapy using small molecule inhibitors in human cancer.

Abstract
BACKGROUND/AIMS Relapse, metastasis, and chemo-resistance are the main factors responsible for the failure of surgical treatment of malignant tumors, and typically are the main obstacles to effective cancer treatment. Although significant advances have been made in the field of cancer chemotherapy, many patients still receive inadequate treatment due to the severe adverse effects of these drugs, resulting in an inability to reach therapeutic concentrations at the tumor site with systemic chemotherapy. Thus, a biological patch loaded with chemotherapeutic drugs could be an ideal strategy for the treatment of cancer at the tumor site. METHODS We developed an acellular matrix using the submucosa of porcine jejunum, then loaded this matrix with different amounts of 5-fluorouracil (5-FU) and rapamycin nanoparticles. Cell proliferation and apoptosis were analyzed by flow cytometry and related markers were evaluated using real-time PCR and western blotting. The patches were evaluated in vitro to characterize their release kinetics and therapeutic feasibility. We then analyzed the therapeutic efficacy and systemic toxicity of these patches in vivo by using them in a mouse model of colon cancer. RESULTS The patches delivered 5-FU and rapamycin in a controlled manner for more than 8 weeks, arrested the cell cycle of LoVo cells and sw480 cells at G2/M phase, and induced apoptosis in vitro. The patches also suppressed the growth of xenografted tumors in vivo with lower adverse effects than typically observed with systemic administration of these drugs. CONCLUSION We demonstrated that patches loaded with 5-FU-RAPA-PLA-NP significantly inhibited the growth of colon cancer in vitro and in vivo. These results demonstrated the feasibility of the use of a multi-effect biological patch for cancer treatment.

Abstract
Purpose To determine the maximum tolerated dose (MTD), toxicities, and pharmacodynamics effects of sirolimus combined with oral metronomic topotecan and cyclophosphamide in a pediatric population. Materials and Methods Patients who were 1 to 30 years of age with relapsed/refractory solid tumors (including CNS) were eligible. Patients received daily oral sirolimus and cyclophosphamide (25-50 mg/m2/dose) on days 1-21 and oral topotecan (0.8 mg/m2/dose) on days 1-14 in 28-day cycles. Sirolimus steady-state plasma trough concentrations of 3-7.9 ng/mL and 8-12.0 ng/mL were evaluated, with dose escalation based on a 3+3 phase 1 design. Biomarkers of angiogenesis were also evaluated. Results Twenty-one patients were treated (median age 18 years; range 9-30). Dose-limiting toxicities included myelosuppression, ALT elevation, stomatitis, and hypertriglyceridemia. The MTD was sirolimus with trough goal of 8-12.0 ng/mL; cyclophosphamide 25 mg/m2/dose; and topotecan 0.8 mg/m2/dose. No objective responses were observed. Four patients had prolonged stable disease > 4 cycles (range 4-12). Correlative biomarker analyses demonstrated reductions in thrombospondin-1 (p=0.043) and soluble vascular endothelial growth factor receptor-2 plasma concentrations at 21 days compared to baseline. Conclusions The combination of oral sirolimus, topotecan, and cyclophosphamide was well tolerated and biomarker studies demonstrated modulation of angiogenic pathways with this regimen.

Abstract
Autoimmune disease occurs when the immune system incorrectly targets the body's own tissue. Inflammatory CD4+ T cell phenotypes, such as TH1 and TH17, are key drivers of this attack. Recent studies demonstrate treatment with rapamycin-a key inhibitor of the mTOR pathway-can skew T cell development, moving T cell responses away from inflammatory phenotypes and toward regulatory T cells (TREGS). TREGS are important in inducing and maintaining tolerance to self-antigens, creating new potential to treat autoimmune diseases more effectively and specifically. Next generation analogs of rapamycin, such as everolimus and temsirolimus, confer increased potency with reduced toxicity, but are understudied in the context of autoimmunity. Further, these drugs are still broadly-acting and require frequent treatment due to short half-lives. Thus, there is strong interest in harnessing the unique properties of biomaterials-controlled drug release and targeting, for example, to improve autoimmune therapies. Using second generation mTOR inhibitors and rapamycin, we prepared sets of degradable polymer particles from poly(lactide-co-glycolide). We then used these materials to assess physicochemical properties and the ability to control autoimmune inflammation in a primary cell co-culture model. Treatment with particle formulations resulted in significant dose-dependent decreases in dendritic cell activation, T cell proliferation, inflammatory cytokines, and frequencies of inflammatory TH1 phenotypes. Considering the current limitations of rapamycin, and the potential of next-generation analogs, this work provides a screening platform for biomaterials and sets the stage for in vivo evaluation, where delivery kinetics, stability, and targeting could improve autoimmune therapies through biomaterial-enabled delivery.

Abstract
The rapid development of nanotechnology provides alternative approaches to overcome several limitations of conventional anti-cancer therapy. Drug targeting using functionalized nanoparticles to advance their transport to the dedicated site, became a new standard in novel anti-cancer methods. In effect, the employment of nanoparticles during design of antineoplastic drugs helps to improve pharmacokinetic properties, with subsequent development of high specific, non-toxic and biocompatible anti-cancer agents. However, the physicochemical and biological diversity of nanomaterials and a broad spectrum of unique features influencing their biological action requires continuous research to assess their activity. Among numerous nanosystems designed to eradicate cancer cells, only a limited number of them entered the clinical trials. It is anticipated that progress in development of nanotechnology-based anti-cancer materials will provide modern, individualized anti-cancer therapies assuring decrease in morbidity and mortality from cancer diseases. In this review we discussed the implication of nanomaterials in design of new drugs for effective antineoplastic therapy and describe a variety of mechanisms and challenges for selective tumor targeting. We emphasized the recent advantages in the field of nanotechnology-based strategies to fight cancer and discussed their part in effective anti-cancer therapy and successful drug delivery.

Abstract
The phosphoinositide 3-kinase/Akt pathway activation commonly occurs in various types of human cancer and has an important role in chemoresistance. Combination of traditional chemotherapy drugs and molecular-targeted agents is a promising strategy for cancer therapy, which has shown enhanced cytotoxicity and lower drug resistance. The present study found that the Akt inhibitor, MK-2206, can increase the effect of cisplatin in the gastric cancer cell line AGS, which has higher Akt phosphorylation, but exhibited a poor combination effect in MKN-45 and MGC-803 cells, which have limited Akt activation. The MTT assay demonstrated that sequential treatment of cisplatin, followed by the Akt inhibitor, MK-2206, caused a synergistic effect of proliferation inhibition, and the apoptosis assay by propidium iodide/fluorescein isothiocyanate staining also showed that combination treatment induced more apoptosis compared to the monotherapy groups. Using western blot analysis, MK-2206 was shown to significantly suppress the phosphorylation of Akt (Ser473), however, the expression of total Akt remained the same, and the combination treatment also increased the expression of cleaved poly adenosine diphosphate ribose polymerase, which contributed to apoptosis.
