  2022-01-18

  

  12-Hydroxyfarnesyl diphosphate (6) was synthesised in three steps starting from commercially available (E,E)-farnesol (10) (Scheme 5). Chlorination of 10 gave farnesyl chloride (11) in a quantitative yield, which was carried forward without purification. The following step was a selenium dioxide-c

• The first phase of insulin secretion

  2022-01-17

  

  The first phase of insulin secretion is due to calcium signaling because of glucose sensing, increased cytoplasmic ATP levels, cellular depolarization, calcium influx and activation of calcium sensing molecules that eventually causes the fusion of the insulin granules to plasma membrane (exocytosis)

  2022-01-17

  

  Biliary tract cancers (BTC) are categorized into intrahepatic, perihilar, extrahepatic BTC (or cholangiocarcinoma) as well as gallbladder cancer (GBC). Although the incidence of BTC is low in developed countries (3% of gastrointestinal cancers), BTC is the second most common primary liver tumor afte

  2022-01-17

  

  Mammals have three known Gli proteins: Gli-1, -2 and -3. Gli-1 does not undergo proteosomal degradation and hence, remains untruncated and always acts as a transcription promoter. Gli-1 is an important target gene for Gli-2. Full-length Gli-2 accumulates when Smo is activated because activated Smo p

  HCC is one of the most prevalent malignant tumors and a leading cause of cancer-related death, globally [[11], [12], [13]]. Hepatitis B virus (HBV) infection is closely related to the development of liver diseases [[14], [15], [16], [17]]. More than 350 million people are chronically infected with H

  2022-01-17

  

  Introduction In the 1980s, nitric oxide (NO) was first characterized as critical to both innate immunity and endogenous signaling in animals [[1], [2], [3], [4], [5]]. NO was the first gaseous signaling molecule synthesized by animals to have its biochemical signaling pathway fully described [2]. P

  2022-01-17

  

  The beta-catenin/TCF complex is an important target in the Wnt/beta-catenin pathway. This complex has proven challenging to target. However, natural inhibitors of this complex have been identified. One group of inhibitors is called the inhibitors of Wnt response (IWR-1/2). IWR-1/2 targets Axin and s

  Crystal structures from soluble E2 constructs (Khan et al., 2014; Kong et al., 2013) have revealed globular protein with no regular structure in spite of having eight disulphide bonds (Kong et al., 2013). Although 62% of the protein exists in loops or disordered structures, overall it was well-defin

  At the second step, blind docking simulation of 150 independent runs was performed with smaller grid box. Structures of open (1v4t.pdb), semi-closed (4dch.pdb) and two structures of closed configuration of GK (pdb codes are 1v4s and 3vev) were used for simulation (for detailed explanations on can se

  Various strategies have been pursued in the search for GIPR antagonists. Antibodies raised against both GIP(1–42) [14], [15] or the GIPR [16], [17], a small molecule antagonist [18], amino farnesyl diphosphate synthase substitutions of GIP(1–42) [19], and various GIP(1–42) truncations and modificati

  Determination of enzyme activity differs from other analytical procedures. In this glycogen phosphorylase case, instead of enzyme concentration, a substrate depletion or product accumulation should be monitored. Such approach allows calculating activity basis of calibration curves performed for enz

  Zn2+ is the second most abundant trace metal in many cells and neurons in the brain. It regulates cellular functions such as gene expression, epigenetic enzymatic activity, protein structural stability, and neuronal plasticity. Zn2+ is particularly abundant in the cortex and limbic system, including
