Named after the two-faced Roman god, Janus PNAs are double-sided, allowing them to bind to both strands of a DNA and RNA molecule. This hairpin structure in the Huntington’s RNA seemed that it would be a promising target for the Janus PNAs. In Huntington's disease, the repetition of the CAG triplet creates a hairpin loop that can trap proteins.

2002-6-1 · The Janus-faced role for CD44/PG in tumor progression is evident today, though CD44 was introduced early on as promoter of tumor metastasis or even as a metastasis gene (i.e. CD44v6). 76 Analysis of the available data based on clinicopathological studies of various malignancies produced three major patterns of CD44/proteoglycan alterations in human cancer.

The Rho family of GTPases consists of several small proteins that have been described as molecular switches, playing important roles in a wide variety of fundamental cellular processes and in human diseases such as cancer. These proteins, active in the GTP conformation and inactive in the GDP form, are in turn regulated by guanine nucleotide

Renal fibrosis is a major hallmark of CKD, regardless of the underlying etiology. In fibrosis development and progression, myofibroblasts play a pivotal role, producing extracellular matrix and interacting with various resident cells in the kidney.

A Janus molecule (or Janus-faced molecule) is a molecule which can represent both beneficial and toxic effects. The term Janus-faced molecule is derived from the ancient Roman god, Janus. Janus is depicted as having two faces; one facing the past and one facing the future. This is synonymous to a Janus molecule having two distinct purposes: a beneficial and a toxic purpose depending on its

[2] In the case of cholesterol, the property that makes cholesterol useful in cell membranes, namely its absolute insolubility in water, also makes it lethal. Besides their vital role in hemostasis and thrombosis, platelets are also recognized to be involved in cancer, where they play an unexpected central role: They actively influence cancer cell behavior, but, on the other hand, platelet physiology and phenotype are impacted by tumor cells.

This implies that NO is a janus-faced molecule and acts as a double-edged sword in vascular complications in diabetes. Further, NO is synthesized from l -arginine via the action of NO synthase (NOS), while NOS is blocked by endogenous l -arginine analogues such as asymmetric dimethylarginine (ADMA), a naturally occurring amino acid which is found in the plasma and various tissues.
