Epicardial adipose tissue and cardiac lipotoxicity: A review
(Elsevier Inc., 2023-07-05T00:00:00) Mukherjee, Anirban Goutam; Renu, Kaviyarasi; Gopalakrishnan, Abilash Valsala; Jayaraj, Rama; Dey, Abhijit; Vellingiri, Balachandar; Ganesan, Raja
Epicardial adipose tissue (EAT) has morphological and physiological contiguity with the myocardium and coronary arteries, making it a visceral fat deposit with some unique properties. Under normal circumstances, EAT exhibits biochemical, mechanical, and thermogenic cardioprotective characteristics. Under clinical processes, epicardial fat can directly impact the heart and coronary arteries by secreting proinflammatory cytokines via vasocrine or paracrine mechanisms. It is still not apparent what factors affect this equilibrium. Returning epicardial fat to its physiological purpose may be possible by enhanced local vascularization, weight loss, and focused pharmacological therapies. This review centers on EAT's developing physiological and pathophysiological dimensions and its various and pioneering clinical utilities. � 2023 Elsevier Inc.
HPV-associated cancers: insights into the mechanistic scenario and latest updates
(Springer, 2023-06-26T00:00:00) Mukherjee, Anirban Goutam; Ramesh Wanjari, Uddesh; Valsala Gopalakrishnan, Abilash; Jayaraj, Rama; Katturajan, Ramkumar; Kannampuzha, Sandra; Murali, Reshma; Namachivayam, Arunraj; Evan Prince, Sabina; Vellingiri, Balachandar; Dey, Abhijit; Renu, Kaviyarasi
Cancer and related diseases are the second leading cause of death worldwide. The human papillomavirus (HPV) is an infectious agent that can be spread mainly through sexual contact and has been linked to several malignancies in both sexes. HPV is linked to almost all cases of cervical cancer. It is also linked to many head and neck cancer (HNC) cases, especially oropharyngeal cancer. Also, some HPV-related cancers, like vaginal, vulvar, penile, and anal cancers, are related to the anogenital area. Over the past few decades, testing for and preventing cervical cancer has improved, but anogenital cancers are still harder to confirm. HPV16 and HPV18 have been extensively researched due to their significant carcinogenic potential. The products of two early viral genes, E6 and E7, have been identified as playing crucial roles in cellular transformation, as emphasized by biological investigations. The complete characterization of numerous mechanisms employed by E6 and E7 in undermining the regulation of essential cellular processes has significantly contributed to our comprehension of HPV-induced cancer progression. This review focuses on the various types of cancers caused by HPV infection and also sheds light on the signaling cascades involved in the same. � 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Onco-Pathogen Mediated Cancer Progression and Associated Signaling Pathways in Cancer Development
(MDPI, 2023-05-28T00:00:00) Kannampuzha, Sandra; Gopalakrishnan, Abilash Valsala; Padinharayil, Hafiza; Alappat, Reema Rose; Anilkumar, Kavya V.; George, Alex; Dey, Abhijit; Vellingiri, Balachandar; Madhyastha, Harishkumar; Ganesan, Raja; Ramesh, Thiyagarajan; Jayaraj, Rama; Prabakaran, D.S.
Infection with viruses, bacteria, and parasites are thought to be the underlying cause of about 8�17% of the world�s cancer burden, i.e., approximately one in every five malignancies globally is caused by an infectious pathogen. Oncogenesis is thought to be aided by eleven major pathogens. It is crucial to identify microorganisms that potentially act as human carcinogens and to understand how exposure to such pathogens occur as well as the following carcinogenic pathways they induce. Gaining knowledge in this field will give important suggestions for effective pathogen-driven cancer care, control, and, ultimately, prevention. This review will mainly focus on the major onco-pathogens and the types of cancer caused by them. It will also discuss the major pathways which, when altered, lead to the progression of these cancers. � 2023 by the authors.
Recent advances in understanding brain cancer metabolomics: a review
(Springer, 2023-07-10T00:00:00) Mukherjee, Anirban Goutam; Gopalakrishnan, Abilash Valsala; Jayaraj, Rama; Ganesan, Raja; Renu, Kaviyarasi; Vellingiri, Balachandar; Dey, Abhijit; Parveen, Mohamudha
Regardless of the significant progress made in surgical techniques and adjuvant therapies, brain tumors are a major contributor to cancer-related morbidity and mortality in both pediatric and adult populations. Gliomas represent a significant proportion of cerebral neoplasms, exhibiting diverse levels of malignancy. The etiology and mechanisms of resistance of this malignancy are inadequately comprehended, and the optimization of patient diagnosis and prognosis is a challenge due to the diversity of the disease and the restricted availability of therapeutic options. Metabolomics refers to the comprehensive analysis of endogenous and exogenous small molecules, both in a targeted and untargeted manner, that enables the characterization of an individual�s phenotype and offers valuable insights into cellular activity, particularly in the context of cancer biology, including brain tumor biology. Metabolomics has garnered attention in current years due to its potential to facilitate comprehension of the dynamic spatiotemporal regulatory network of enzymes and metabolites that enables cancer cells to adapt to their environment and foster the development of tumors. Metabolic changes are widely acknowledged as a significant characteristic for tracking the advancement of diseases, treatment efficacy, and identifying novel molecular targets for successful medical management. Metabolomics has emerged as an exciting area for personalized medicine and drug discovery, utilizing advanced analytical techniques such as nuclear magnetic resonance spectroscopy (MRS) and mass spectrometry (MS) to achieve high-throughput analysis. This review examines and highlights the latest developments in MRS, MS, and other technologies in studying human brain tumor metabolomics. � 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
