Telomeres and telomerase may play a crucial role in cellular aging, cancer initiation, and tumor survival, but a thorough understanding of the mechanisms involved in telomere length (TL) maintenance and telomerase expression gives experts the tools they need to develop diagnostic tools, determine disease prognosis, and formulate effective anticancer therapeutics.

A Closer Look at Lipid Rafts

Posted by The Protein Man on Aug 18, 2021 3:45:00 PM


What are lipid rafts and what purpose do they serve? Despite numerous studies, the existence and exact nature of lipid rafts continue to elude researchers due to the apparent limitations in the methods used in isolating and studying them. However, recent studies indicate that these rafts may play an important role in the compartmentalization of cellular membrane processes and in the development of various diseases.

Revisiting the ACE2 Receptor

Posted by The Protein Man on Jul 27, 2021 1:30:00 PM


Understanding the mechanisms of COVID-19 endocytosis is a critical component when monitoring nascent variants of COVID-19. Increased affinity to the ACE2 receptor may lead to an increase in pathogenicity and higher transmissibility. The Delta variant of COVID-19 has been shown to have substitutions and or combinations of substitutions in the spike protein. More data is required to fully characterize the pathogenicity of each variant. The Delta variant makes up about 80% of new observed mutants. The characterization of this variant is extensive and demonstrates increased transmissibility (2) along with a significant increase in hospitalization of unvaccinated individuals (3).

Considering these observations, let’s once again take a look at the ACE2 receptor and it’s role in the endocytosis of COVID-19 into the human cell.
