Abstract
The most prevalent primary cancer in bone tissues is osteosarcoma (OS). For thousands
of years, traditional Chinese medicines (TCM) have been employed and their use offers
valuable insights into the treatment of OS. Natural phenolic acid found in a variety
of foods and herbs is called gallic acid (GA). GA has a number of well-established
pharmacological properties including anti-oxidation and anti-inflammatory properties.
Its biological role in OS is still not entirely known, nevertheless. GA's putative
anti-cancer qualities were assessed in MG63 cells. In these OS cells, its effects
on migration, apoptosis, cell cycle and proliferation were investigated.
The JAK-STAT signalling pathway was identified using experiments using flow cytometry
and RT-PCR. Molecular docking was used to examine the in silico impact of GA on
proteins. GA was discovered in this work to prevent invasion and metastasis in addition
to causing cell cycle arrest and death in OS cells which in turn suppresses tumour
growth in vitro. The binding affinity of GA with the JAK-STAT proteins was determined
using the Autodock program. When viewed as a whole, our findings showed that GA
impeded tumour growth in OS cells by regulating the JAK-STAT, TGF and SMAD signalling
pathways.
