Research review (peer-reviewed)abstract
- Background Ubiquitin ligases or E3 ligases are well programmed to regulate molecular interactions that operate at a post-translational level. Skp, Cullin, F-box containing complex (or SCF complex) is a multidomain E3 ligase known to mediate the degradation of a wide range of proteins through the proteasomal pathway. The three-dimensional domain architecture of SCF family proteins suggests that it operates through a novel and adaptable "super-enzymatic" process that might respond to targeted therapeutic modalities in cancer. Recent findings Several F-box containing proteins have been characterized either as tumor suppressors (FBXW8, FBXL3, FBXW8, FBXL3, FBXO1, FBXO4, and FBXO18) or as oncogenes (FBXO5, FBXO9, and SKP2). Besides, F-box members like beta TrcP1 and beta TrcP2, the ones with context-dependent functionality, have also been studied and reported. FBXW7 is a well-studied F-box protein and is a tumor suppressor. FBXW7 regulates the activity of a range of substrates, such as c-Myc, cyclin E, mTOR, c-Jun, NOTCH, myeloid cell leukemia sequence-1 (MCL1), AURKA, NOTCH through the well-known ubiquitin-proteasome system (UPS)-mediated degradation pathway. NOTCH signaling is a primitive pathway that plays a crucial role in maintaining normal tissue homeostasis. FBXW7 regulates NOTCH protein activity by controlling its half-life, thereby maintaining optimum protein levels in tissue. However, aberrations in the FBXW7 or NOTCH expression levels can lead to poor prognosis and detrimental outcomes in patients. Therefore, the FBXW7-NOTCH axis has been a subject of intense study and research over the years, especially around the interactome's role in driving cancer development and progression. Several studies have reported the effect of FBXW7 and NOTCH mutations on normal tissue behavior. The current review attempts to critically analyze these mutations prognostic value in a wide range of tumors. Furthermore, the review summarizes the recent findings pertaining to the FBXW7 and NOTCH interactome and its involvement in phosphorylation-related events, cell cycle, proliferation, apoptosis, and metastasis. Conclusion The review concludes by positioning FBXW7 as an effective diagnostic marker in tumors and by listing out recent advancements made in cancer therapeutics in identifying protocols targeting the FBXW7-NOTCH aberrations in tumors.

Recent Advances in Chronotherapy Targeting Respiratory Diseases
- 2021
-
In: Pharmaceutics. - : MDPI. - 1999-4923. ; 13:12
-
Research review (peer-reviewed)abstract
- Respiratory diseases contribute to a significant percentage of mortality and morbidity worldwide. The circadian rhythm is a natural biological process where our bodily functions align with the 24 h oscillation (sleep-wake cycle) process and are controlled by the circadian clock protein/gene. Disruption of the circadian rhythm could alter normal lung function. Chronotherapy is a type of therapy provided at specific time intervals based on an individual's circadian rhythm. This would allow the drug to show optimum action, and thereby modulate its pharmacokinetics to lessen unwanted or unintended effects. In this review, we deliberated on the recent advances employed in chrono-targeted therapeutics for chronic respiratory diseases.

Extraction and Purification of PUFA from Microbial Biomass
- 2020
-
In: Nutraceutical Fatty Acids from Oleaginous Microalgae. - : John Wiley & Sons. ; , s. 249-279
-
Book chapter (other academic/artistic)abstract
- Polyunsaturated fatty acids (PUFAs) are essential for human beings to maintain bio functions that would prevent diseases such as depression, neurological diseases, inflammation, autoimmune diseases and cardiovascular disease. Human beings are unable to synthesize essential PUFAs in the body and therefore, they are taken up from different food sources. The major sources of PUFAs are fish, eggs, milk, fruits and seed oil. However, microbes such as microalgae, bacteria and fungi have good capability for the production of PUFAs under controlled conditions. The establishment of a cost‐effective, reliable and eco‐friendly technique for extraction and purification of PUFAs from microbes is a crucial point. This chapter summarizes and describes the various physico‐chemical methods applied to extract and purify PUFAs from microbes.

Targeting LIN28 : a new hope in prostate cancer theranostics
- 2021
-
In: Future Oncology. - : Future Medicine. - 1479-6694 .- 1744-8301. ; 17:29, s. 3873-3880
-
Journal article (peer-reviewed)abstract
- The mortality and morbidity rates for prostate cancer have recently increased to alarming levels, rising higher than lung cancer. Due to a lack of drug targets and molecular probes, existing theranostic techniques are limited. Human LIN28A and its paralog LIN28B overexpression are associated with a number of tumors resulting in a remarkable increase in cancer aggression and poor prognoses. The current review aims to highlight recent work identifying the key roles of LIN28A and LIN28B in prostate cancer, and to instigate further preclinical and clinical research in this important area.
