Melatonin is a ubiquitous molecule present in almost every live being from bacteria to
humans. In vertebrates, besides being produced in peripheral tissues and acting as an …

Melatonin receptors are seven transmembrane‐spanning proteins belonging to the GPCR
superfamily. In mammals, two melatonin receptor subtypes exist‐MT1 and MT2‐encoded by …

Luminescent semiconductor nanocrystals or quantum dots (QDs) provide exquisite electro-
optical properties that are ideal for biological sensing applications. Unlike traditional …

The pineal hormone melatonin has attracted great scientific interest since its discovery in
1958. Despite the enormous number of basic and clinical studies the exact role of melatonin …

Many of melatonin's actions are mediated through interaction with the G-protein coupled
membrane bound melatonin receptors type 1 and type 2 (MT1 and MT2, respectively) or …

Melatonin production is highly conserved in nature through different species including
bacteria, unicellular eukaryotes, algae, plants invertebrates, and vertebrates (Hardeland et …

Melatonin, the neurohormone of the pineal gland, is also produced by various other tissues
and cells. It acts via G protein-coupled receptors expressed in various areas of the central …

Melatonin, N‐acetyl‐5‐methoxytryptamine, an evolutionally old molecule, is produced by the
pineal gland in vertebrates, and it binds with high affinity to melatonin receptors, which are …

The hormone melatonin (5-methoxy-N-acetyltryptamine) is synthesized primarily in the
pineal gland and retina, and in several peripheral tissues and organs. In the circulation, the …

The present review discusses recent work on melatonin-mediated circadian regulation, the
metabolic and molecular signaling mechanisms that are involved in human breast cancer …
