Abstract
Natural polymeric hydrogels represent an optimal framework for 3D culture development. This study demonstrates a freeze-thaw-based ionic crosslinking technique for fabricating alginate/carboxymethylcellulose scaffold for culturing human hepatocellular carcinoma, Huh-7 cells to generate 3D spheroids. Consolidating morphological and biomechanical characterization of Alg/CMC scaffolds shows the formation of uniform hydrogels with significant crosslinking (ATR-FTIR), multiscale pores (FE-SEM), swelling/water absorbance, softer texture, viscoelasticity (rheology), spreading nature (contact angle), and degradation rate optimal for 3D culture establishment. The influence of cell seeding density and time with spheroid formation reveals a maximal size of 250-300 μm on day 7. Calcein AM and Propidium iodide staining confirm that a culmination of viable and dead cells generates spheroidal heterogeneity. RT-qPCR in 3D culture against RPL-13 and 2D culture controls indicate an upregulation of E-cadherin, N-cadherin, fibronectin, and integrin α9/β6. Further, western blotting and immunofluorescence confirm the collective display of cellular interactions in 3D spheroids. Thus, the expression profile signifies the role of key genes during the assembly and formation of 3D spheroids in 1%Alg/1%CMC scaffolds with a profound epithelial characteristic. In the future, this study will bring a 3D spheroid model in a platter for elucidating epithelial to mesenchymal transition of cells during in vitro disease modeling.

Combinatorial cetuximab targeted polymeric nanocomplexes reduce PRC1 level and abrogate growth of metastatic hepatocellular carcinoma in vivo with efficient radionuclide uptake.

Abstract
Hepatocellular carcinoma (HCC) is the most aggressive form of cancer with poor drug responses. Developing an effective drug treatment remains a major unmet clinical need for HCC. We report a comprehensive study of combinatorial Cetuximab (Cet) targeted polymeric poly(D, L-lactide-co-glycolide)-b-poly(ethylene glycol) nanocomplexes delivery of Combretastatin A4 (CA4) and 2-Methoxyestradiol (2ME) (Cet-PLGA-b-PEG-CA4 NP + Cet-PLGA-b-PEG-2ME NP) against metastatic HCC in SCID mice. 125I-Cet-PLGA-b-PEG NP showed potent accumulation and retention in HCC tumors with longer circulation time up to 48 h (18 ± 1.0% ID/g, P < .0001). Combinatorial treatment with targeted polymeric nanocomplexes presented significant tumor growth inhibition (85%, P < .0001) than the free drug combinatorial counterpart, effectively inhibited orthotopic HCC and prevented lung metastasis. Combinatorial nanocomplexes treatment significantly blocked PRC1, a novel target of therapeutic response against HCC. Thus, the combinatorial cetuximab-targeted polymeric nanocomplexes possess superior antitumor activity against metastatic HCC and provide supports for the clinical translation ahead.

Identification and evaluation of an appropriate housekeeping gene for real time gene profiling of hepatocellular carcinoma cells cultured in three dimensional scaffold. Mol Biol Rep 2021; 49:797-804.

Abstract
BACKGROUND Assessing an optimal reference gene as an internal control for target gene normalization is important during quantitative real time polymerase chain reaction (RT-qPCR) of three dimensional (3D) cell culture. Especially, gene profiling of cancer cells under a complex 3D microenvironment in a polymer scaffold provides a deeper understanding of tumor functioning in vivo. METHODS AND RESULTS Expression of six housekeeping genes (HKG's): Glyceraldehyde-3-phosphodehydrogenase (GAPDH), β-actin (ACTB), beta-2-microglobulin (B2M), 18S ribosomal RNA (18S rRNA), peptidyl-propyl-isomerase A (PPIA), and ribosomal protein L13 (RPL-13) during two dimensional (2D) culture, and alginate-carboxymethylcellulose scaffold based 3D culture conditioned up to 21 days was analysed for hepatocellular carcinoma (Huh-7) cells. The gene expression studies were performed by determining primer efficiency, melting curve and threshold cycle analysis. Further, RT-qPCR data was validated statistically using geNorm and NormFinder softwares. The study indicated RPL-13, 18S rRNA and B2M to be stable among selected referral HKG candidates. CONCLUSION An exploration of a reliable HKG is necessary for normalization of gene expression in RT-qPCR during varying cell culture conditions.

Distinct stratification of normal liver, hepatocellular carcinoma (HCC), and anticancer nanomedicine-treated- tumor tissues by Raman fingerprinting for HCC therapeutic monitoring. NANOMEDICINE-NANOTECHNOLOGY BIOLOGY AND MEDICINE 2021; 33:102352. [PMID: 33418135 DOI: 10.1016/j.nano.2020.102352] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 12/04/2020] [Accepted: 12/05/2020] [Indexed: 01/22/2023]
Abstract
Hepatocellular carcinomas (HCCs) are highly vascularized neoplasms with poor prognosis. Nanomedicine possesses great potential to deliver therapeutics and diagnostics. The new aspect of this study is that we have monitored, for the first time, the Raman responses to microtubule targeted vascular disrupting agents (MTVDA), MTVDA encapsulated non-targeted, and targeted cetuximab polymeric nanocomplexes delivery of combinatorial therapeutics in HCC tumor tissues of mice. Biochemical differences majorly demarcated apoptotic lipid bodies, and characteristic amide-I features. HCC tumor and healthy liver tissues could be stratified. Raman spectroscopy served as an excellent, rapid, sensitive and cost-effective approach for anticancer nanomedicine distinct stratification of MTVDA encapsulated targeted cetuximab polymeric nanocomplex combinatorials, a significant potential for HCC therapeutic monitoring.

Abstract
Aim: Synthesis of poly-L-lactic acid nanoparticles comprising of microtubule-inhibitor docetaxel and tyrosine kinase inhibitor sorafenib (PLDS NPs) for hepatoma treatment. Materials & methods: PLDS NPs were prepared by the emulsion solvent evaporation method and the anticancer activity was evaluated in Huh7 hepatoma cells. Results: Real-time imaging of quantum dots incorporating poly-L-lactic acid nanoparticles showed a rapid internalization of the nanoparticles in Huh7 cells. PLDS NPs exerted stronger antiproliferative, apoptotic and antiangiogenic effects than free single drug counterparts. They strongly promoted microtubule bundling, multinucleation and increased mitotic index in Huh7 cells. They also inhibited the expression of pERK1/2, pAKT and cyclin D1. Conclusion: We developed a single-nanoscale platform for dual drug delivery and high-sensitivity quantum dots imaging for hepatoma treatment. [Formula: see text].

Abstract
The stilbenoid combretastatin and its derivatives are potent inhibitors of angiogenesis and cell proliferation and induce apoptosis. They disrupt cytoskeletal dynamics and modulate cell morphology, motility, and invasion. Hence they have been viewed as potential as anticancer agents. The impediments of poor solubility and bioavailability and the spontaneous geometric isomerisation of combretastatin into an inactive form have led to intensive efforts towards evolving novel analogues to provide more efficacious biological outcome. Importantly, isomerically stable and biologically active cis-restricted analogues have been synthesised and tested. However, very few analogues have been tested in preclinical models to assess their effects on processes relevant to cancer development and progression. Hence the accent here is on the signalling systems operated by the new derivatives and their biological effects with reference to cancer progression. Combretastatins modulate an extensive network of signalling emphasising their varied versatility. Harnessing these systems and accentuating or counteracting aberrant signalling could open potential avenues of approach to the designing of novel derivatives with enhanced performance. The import of mammalian target of rapamycin pathway, which co-ordinates growth factor receptor signalling, epithelial-mesenchymal transition activation and angiogenic signalling, is emphasised. It may be viewed as a prime target for allosteric inhibition in combination with combretastatin analogues to ascertain their potential in cancer control.
