Abstract
Escape from cell death is one of the most prominent features of tumor cells and is closely related to the dysregulation of Bcl-2 family proteins. Among them, the anti-apoptotic protein Mcl-1 (myeloid cell leukaemia-1) acts as a master regulator of apoptosis in various human malignancies. The Mcl-1 -1 protein, whose main function is to protect tumor cells from apoptosis, is not the only product of the anti-apoptotic gene MCL1. On the contrary, another product of this gene, the shortened Mcl-1S protein, formed by alternative splicing, serves as a negative regulator of Mcl-1. Increased levels of Mcl-1S lead to inhibition of apoptosis-protective Mcl-1 and, consequently, tumor cell death by apoptosis (Senichkin, 2018). Mcl-1 inhibitors are currently being developed, which opens new perspectives to fight the hitherto untreatable addiction of cancer cells (Bolomsky et al., 2020).
期刊介绍：
Cardiometry is an open access biannual electronic journal founded in 2012. It refers to medicine, particularly to cardiology, as well as oncocardiology and allied science of biophysics and medical equipment engineering. We publish mainly high quality original articles, reports, case reports, reviews and lectures in the field of the theory of cardiovascular system functioning, principles of cardiometry, its diagnostic methods, cardiovascular system therapy from the aspect of cardiometry, system and particular approaches to maintaining health, engineering peculiarities in cardiometry developing. The interdisciplinary areas of the journal are: hemodynamics, biophysics, biochemistry, metrology. The target audience of our Journal covers healthcare providers including cardiologists and general practitioners, bioengineers, biophysics, medical equipment, especially cardiology diagnostics device, developers, educators, nurses, healthcare decision-makers, people with cardiovascular diseases, cardiology and engineering universities and schools, state and private clinics. Cardiometry is aimed to provide a wide forum for exchange of information and public discussion on above scientific issues for the mentioned experts.
