ions help regulate homeostasis in our bodies‚ as well as allowing us to move‚ absorb food‚ heal‚ and reproduce. Understanding how these ions work within our bodies will allow us to comprehend the physiology behind muscle contraction‚ nerve signaling and cell signaling.

Cellular signaling has been a highly studied topic in biological and medical areas‚ being essential for many cellular processes. The efforts toward the comprehension of signaling pathways may help to understand a large range of molecular mechanisms such as those involved in host parasite interaction or in many types of cancer (Hanahan and Weinberg 2011). Cellular signaling is driven mainly by protein phosphorylation and dephosphorylation events‚ controlled by protein kinases and protein phosphatases

Outline notes: 1. Lecture - General signaling principles Geraint Thomas Introduction Failure in cell signaling influences the normal cell homeostasis and finally can results in diseases. (According to OMIM between 250-2500 diseases are related to genetic changes e.g. IBD‚ Huntington‚ etc) Signals induce transitions from state 1 to state 2. Even for staying alive cells need constant signaling. Characteristics of a signal/change: - Perturbation from steady state

Introduction First discovered as the major signal transducer in interferon-mediated gene activation‚ STATs (signal transducers and activators of transcription) are now known to play a significant role in signal transduction for most cytokines. STATs represent a family of conserved proteins‚ seven of which have

Through endocrine signaling‚ the signaling molecule or hormone is produced by a gland and discharged into the blood where it travels until it reaches certain blood cells distant from its place of origin on which it exerts its action. This is a long distance communication process. The signaling molecule is mainly of protein origin‚ although there is also a varied range of steroidal hormones.

The word ‘Hypothesis is derived from a Greek word‚ which means ‘to suppose’. It is usually considered as the principal instrument in research. For a researcher it is a formal question that he or she intends to resolve. In this way a hypothesis may be defined as a proposition or a supposition. The main function of hypothesis is to guide the collection and processing of materials and direct the research. Hypothesis is a tentative conclusion. It is facts based theory. A research scholar will analyze
