Abstract
Gemcitabine (GEM) is an important chemotherapeutic agent used alone or in combination with other anticancer agents for the treatment of various solid tumors. In this study, the potential of a dietary supplement, α-tocopherol succinate (TOS) was investigated in combination with GEM by utilizing human serum albumin-based nanoparticles (HSA NPs). The developed nanoparticles were characterized using DLS, SEM and FTIR and evaluated in a panel of cell lines to inspect cytotoxic efficacy. The ratio metric selected combination of the NPs was further investigated in human pancreatic cancer cell line (MIA PaCa-2 cells) to assess the cellular death mechanism via a myriad of biochemical and bio-analytical assays including nuclear morphometric analysis by DAPI staining, ROS generation, MMP loss, intracellular calcium release, in vitro clonogenic assay, cell migration assay, cell cycle analysis, immunocytochemical staining followed by western blotting, Annexin V-FITC and cellular uptake studies. The desolvation-crosslinking method was used to prepare the NPs. The average size of TOS-HSA NPs and GEM-HSA NPs was found to be 189.47 ± 5 nm and 143.42 ± 7.4 nm, respectively. In combination, the developed nanoparticles exhibited synergism by enhancing cytotoxicity in a fixed molar ratio. The selected combination also significantly triggered ROS generation and mitochondrial destabilization, alleviated cell migration potential and clonogenic cell survival in MIA PaCa-2 cells. Further, cell cycle analysis, Annexin-V FITC assay and caspase-3 activation, up regulation of Bax and down regulation of Bcl-2 protein confirmed the occurrence of apoptotic event coupled with the G0/G1 phase arrest. Nanocarriers based this combination also offered approximately 14-folds dose reduction of GEM. Overall, the combined administration of TOS-HSA NPs and GEM-HSA NPs showed synergistic cytotoxicity accompanied with dose reduction of the gemcitabine. These encouraging findings could have implication in designing micronutrient based-combination therapy with gemcitabine and demands further investigation.

Abstract
The unique physiology of tumors limits the efficacy of chemotherapeutics. In efforts to improve the effectiveness of the existing chemotherapy drugs, nanomedicine emerged as a new hope but proved inadequate due to the transport barriers present within the tumor tissues, which limits the potential of nanomedicine. Dense collagen networks in fibrotic tissues contribute to hindering the penetration of molecular- or nano-scale medicine through tumor interstitium. In the present study, human serum albumin (HSA)-based nanoparticles (NPs) were developed for gemcitabine (GEM) and losartan (LST), which could offer secreted protein acids rich in cysteine (SPARC) and enhanced permeability and retention effect (EPR)-mediated drug accumulation in tumors. Also, the tumor microenvironment (TME) modulation approach using LST was coupled to investigate the impact on antitumor efficacy. GEM-HSA NPs and LST-HSA NPs were prepared by the desolvation-cross-linking method and characterized for size, potential, morphology, drug loading, drug-polymer interactions, and hemocompatibility. For investigating the efficacy of prepared NPs, cytotoxicity and mechanisms of cell death were elucidated in vitro by using various assays. Intracellular uptake studies of prepared HSA NPs indicated their uptake and cytoplasmic localization. Furthermore, in vivo studies demonstrated significantly improved anticancer efficacy of GEM-HSA NPs in combination with LST pretreatment. Extended LST treatment further improved the anticancer potential. It was shown that the improved efficacy of the nanomedicine was correlated with the reduced thrombospondin-1 (TSP-1) and collagen level in tumor tissue upon LST pretreatment. Moreover, this approach exhibited augmented nanomedicine accumulation in the tumor, and hematological, biochemical, and tissue histology indicated the safety profile of this combination regimen. Concisely, the undertaken study demonstrated the potential of the triple targeting (SPARC, EPR, TME modulation) approach for augmented efficacy of chemotherapeutics.

Abstract
Despite a great deal of efforts made by researchers and the advances in the technology, the treatment of
cancer is very challenging. Significant advances in the field of cancer therapeutics have been made but due to the
complexity of solid tumor microenvironment, specially their dense extracellular matrix (which makes the conditions
favorable for cancer growth, metastasis and acts as a barrier to the chemotherapeutic drugs as well as
nanomedicine), the treatment of solid tumors is difficult. Overexpression of extracellular matrix components such
as collagen, hyaluronan and proteoglycans in solid tumor leads to high interstitial fluid pressure, hypoxia, vascular
collapse and poor perfusion which hinder the diffusion and convection of the drugs into the tumor tissue. This
leads to the emergence of drug resistance and poor antitumor efficacy of chemotherapeutics. A number of approaches
are being investigated in order to modulate this barrier for improved outcome of cancer chemotherapy.
In this review, recent advances in the various approaches for the modulation of the extracellular matrix barrier of
the solid tumor are covered and significant findings are discussed in an attempt to facilitate more investigations in
this potential area to normalize the tumor extracellular matrix for improving drug exposure to solid tumor.
