Submitted papers should be well formatted and use good English. For details about the APC please see here. There is an Article Processing Charge (APC) for publication in this Please visit the Instructions for Authors page before submitting a manuscript. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. All manuscripts are thoroughly refereed through a single-blind peer-review process. Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website. Research articles, review articles as well as short communications are invited. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. All submissions that pass pre-check are peer-reviewed. Manuscripts can be submitted until the deadline. Once you are registered, click here to go to the submission form. Manuscripts should be submitted online at by registering and logging in to this website. In the Special Issue “Signal Transduction Pathways Involved in Regulation of Normal and Tumor Cells” we welcome manuscripts, either original work or review articles, focused on molecules or mechanisms involved in the transduction of signals. Malignancy-inducing alterations in cancer cells frequently affect the intensity and duration of the transduced signals within the cell by striking molecules either directly involved in receiving and processing information or fulfilling a function as inhibitory and regulatory constraints of these processes. Disturbances in the multilayered network of signal transduction harm the cellular adjustment and result in diseases like cancer. Subsequently, the entire autocrine and paracrine information in the approximate surrounding is converted to a cellular response. An important form of intercellular communication functions via signalling cues released in the microenvironment.
allow specific ions to flow into or out of the cell in response to binding of a chemical messengerĤ.The human body consists of approximately 100,000 billion cells, necessitating their well-orchestrated interaction to guarantee proper functionality. Active G proteins modulate the activity of various ion channels and enzymes. couple to GTP binding proteins (G-proteins) inside the cell to activate them. have intrinsic enzymatic activity or are associated with an intracellular enzyme. Enzyme-Linked Receptors (Receptor Kinases) There are 4 Classes of Signal Transducing Receptors:ġ. Receptors Responsible for Signal Transduction molecules that transmit signals received at receptors (i.e., cAMP, cGMP, DNA binding, ions). hormones, neurotransmitters, pharmacological agonists) For example, the heart is an effector of norepinephrine released from nerve terminals. when different signals increase or decrease the production of other signals. when a signal from a single receptor can activate multiple effectors. when signals from a variety of unrelated receptors can converge and activate common effectors. Signal Transduction Pathways are not always linear. Insulin then stimulates its receptors on these cells to initiate a cascade of events leading to expression of glucose transporters to allow cells to take glucose in for energy utilization. insulin is synthesized and secreted by pancreatic beta cells, released into the blood and transported to cells all over the body. increasing a signal so that minimal receptor occupation by small amounts of neurotransmitters in the synapse produces significant cellular responses. Suppression of these exaggerated signals may be one way to reduce cell proliferation in cancer. For example, certain signaling pathways become overly active in cancerous cells. Why is this important? Identifying the cellular events that take place upon receptor activation is necessary for designing pharmacological agents that potentiate (increase) or diminish (decrease) signaling. modification of the cell membrane potential initiated by the movement of ions into or out of the cell. o receptors that initiate biochemical changes accomplish this either by intrinsic enzymatic activities (within the receptor itself) or by activating intracellular messenger molecules. a cascade of events or biochemical changes within the cell. transmission of molecular signals from outside the cell into the cell via cell-surface receptors.
