Papaya seeds are reported to have higher therapeutic potential in comparison to the fruits in which they reside. Thus, the present in-vitro study aimed to evaluate and compare the anti-oxidant, anti-inflammatory and anti-microbial effect of seed extracts on Carica papaya L. (Caricaceae). The bioactive form the seeds were sequentially fractionated with hexane, chloroform, diethyl ether, and methanol in the increasing order of polarity. Total phenolic and flavonoid contents were estimated. These extracts were assessed for an antioxidant property by 1, 1-diphenyl-2-picryl-hydroxyl (DPPH) method and reducing power assay was carried out using the FeCl3 method. Inhibition of 15-lipoxygenase (LOX) by these extracts at 5 -25μg to asses anti-inflammatory capacity was studied.

Nuclear factor erythroid 2 (NFE 2) - related factor 2 (NFE2L2 or NRF2) is one of the transcription factors predominantly related to the expression of antioxidant genes. NRF2 is found to play a pivotal role in the control of redox potential in several tumor characteristics including cancer cell metabolism, stem-cell-like characteristics, tumor aggressiveness, invasion, and metastasis. Further, it was recently discovered that the noncanonical pathway of NRF2 activation was involved in carcinogenesis. Cancer-related changes (e.g., metabolic flexibility) that support cancer progression were found to be redox and NRF2 dependent. The pro or antineoplastic effects of NRF2 are essentially based on the specific molecular characteristics of the type of cancer. Therefore, systematic investigation of NRF2 signaling is necessary to clarify its role in cancer etiology. Understanding the role of NRF2 in triggering gene expressions in different types of cancer is quite challenging which might be useful to target those genes for better clinical outcomes. To decipher the role of NRF2 in tumor formation and progression, large-scale genomic and transcriptomic studies are required to correlate the clinical outcomes with the activity of the NRF2 expression system. This review is an attempt to give insights into the understanding of the role of NRF2 in cancer.

There is a shred of evidence to suggest that Emblica officinalis Gaertn, the botanical name for amla seeds, has greater medicinal potential than amla fruit. We conducted this work to assess the anti-inflammatory, antibacterial, and antioxidant capacities of E. officinalis seed extracts. The bioactive components from the seeds were fractionated using chloroform, hexane, methanol, and diethyl ether, according to the polarity of the solvents. The total amount of phenolic and flavonoid was estimated. Both the reducing power and antioxidant capacities of the extracts were evaluated using the DPPH (1,1-diphenyl-2-picryl-hydrazyl) technique. 15-lipoxygenase (LOX) was inhibited by seed extracts at doses ranging from 5 to 25 micrograms. In silico docking was employed to assess the results. Some human pathogenic microorganisms were tested for their antibacterial activity using the agar disc diffusion method. Escherichia coli, Proteus vulgaris, and Klebsiella pneumonia were inhibited by a methanolic extract with an IC50 value of 58g, making it the most common organic solvent extract. Methanolic extracts also showed good antioxidant and antibacterial activity. Our investigation led us to discover that amla seeds have anti-inflammatory, antioxidant, and antibacterial effects.

Since the last comprehensive assessment of antiangiogenic therapy was published in Breast Cancer Research 3 years ago, clinical trials in a variety of tumour types, including breast cancer, have underscored the key relevance of tumour neovascularization. Bevacizumab, a drug designed to target vascular endothelial cell growth factor, was utilised in many of these studies (VEGF). Clinical trials using antiangiogenic treatment in breast cancer have highlighted the critical role of tumour neovascularization. Personalised medicine will become increasingly important to generate maximum therapeutic benefit to the patient but also to realise the optimal economic advantage from the finite resources available, according to a report by the US Department of Health and Human Services (HHS) and the National Institute for Occupational and Environmental Health (NIH). This overview covers the history of breast tumour neovascularization in both in situ and invasive breast cancer, the processes by which it occurs, and the impact of the microenvironment, with a focus on hypoxia. The regulation of angiogenesis, as well as the antivascular drugs employed in antiangiogenic dosing schedules, both innovative and traditional, are discussed.
