Background: Renal cell carcinoma (RCC) is a seventh ranked malignancy with poor prognosis. RCC is lethal at
metastatic stage as it does not respond to conventional systemic treatments, and there is an urgent need to find
out promising novel biomarkers for effective treatment. The goal of this study was to evaluate the biomarkers that
can be potential therapeutic target and predict effective inhibitors to treat the metastatic stage of RCC.
Methods: We conducted transcriptomic profiling to identify differentially expressed genes associated with RCC.
Molecular pathway analysis was done to identify the canonical pathways and their role in RCC. Tissue microarrays
(TMA) based immunohistochemical stains were used to validate the protein expression of cyclinD1 (CCND1) and were
scored semi-quantitatively from 0 to 3+ on the basis of absence or presence of staining intensity in the tumor cell.
Statistical analysis determined the association of CCND1 expression with RCC. Molecular docking analyses were
performed to check the potential of two natural inhibitors, rutin and curcumin to bind CCND1.
Results: We detected 1490 significantly expressed genes (1034, upregulated and 456, downregulated) in RCC using
cutoff fold change 2 and p value < 0.05. Hes-related family bHLH transcription factor with YRPW motif 1 (HEY1),
neuropilin 2 (NRP2), lymphoid enhancer-binding factor 1 (LEF1), and histone cluster 1 H3h (HIST1H3H) were most
upregulated while aldolase B, fructose-bisphosphate (ALDOB), solute carrier family 12 (SLC12A1), calbindin 1 (CALB1)
were the most down regulated genes in our dataset. Functional analysis revealed Wnt/β-catenin signaling as the
significantly activated canonical pathway (z score = 2.53) involving cyclin D1 (CCND1). CCND1 was overexpressed in
transcriptomic studies (FC = 2.26, p value = 0.0047) and TMA results also showed the positive expression of CCND1 in
53 % (73/139) of RCC cases. The ligands – rutin and curcumin bounded with CCND1 with good affinity.
Conclusion: CCND1 was one of the important upregulated gene identified in microarray and validated by TMA.
Docking study showed that CCND1 may act as a potential therapeutic target and its inhibition could focus on the
migratory, invasive, and metastatic potential of RCC. Further in vivo and in vitro molecular studies are needed to
investigate the therapeutic target potential of CCND1 for RCC treatment. |
