Abstract:

Sex hormone-binding globulin (SHBG) binds androgens and estrogens with high affinity, and regulates the distribution of these sex steroids in the blood and other biological fluids. Liver is the primary site of SHBG production, but the human SHBG transcription unit responsible for this is also expressed in proximal convoluted tubule (PCT) epithelial cells in a transgenic mouse model. Unlike hepatocytes which actively secrete SHBG and retain little immunoreactive SHBG within their cytoplasm, an incompletely glycosylated SHBG isoform has been found to accumulate inside PCT cells. These cells are

Abstract:

Bisphosphonates (BPs) are stable analogues of pyrophosphate widely used for the treatment of bone diseases characterised by increased bone resorption. Studies over the years have shown that the pharmacological potencies of BPs are dependent both on their binding affinities for bone mineral and on their inhibitory actions on osteoclasts. In addition, potential effects on other cell types present locally in the environment of skeletal tissues have been reported. The present study systematically evaluated the relative mineral-binding affinities of individual BPs of clinically relevance in mixture

Abstract:

Botulinum neurotoxins (7 serotypes of BoNTs, named from A to G) and tetanus neurotoxin (TeNT) are the most powerful clostridial toxins (CNTs). They are responsible for botulism and tetanus respectively. TeNT and BoNTs bind to peripheral nerve terminals and inhibit neurotransmitter release from presynaptic neuronal cells by proteolytic cleavage of proteins involved in the fusion of synaptic vesicles with the cell membrane. BoNTs act at the level of Peripheral Nervous System (PNS) causing flaccid paralysis whereas TeNT acts at the level of Central Nervous System (CNS) causing spastic paralysis.

Abstract:

Hygromycin A (HygA) binds to the large ribosomal subunit and inhibits its peptidyl transferase (PT) activity. The presented structural and biochemical data indicate that HygA does not interfere with the initial binding of aminoacyl-tRNA to the A site, but prevents its subsequent adjustment such that it fails to act as a substrate in the PT reaction. Structurally we demonstrate that HygA binds within the peptidyl transferase center (PTC) and induces a unique conformation. Specifically in its ribosomal binding site HygA would overlap and clash with aminoacyl-A76 ribose moiety and, therefore, its

Tol-Pal is composed of a homologous complex of three inner membrane proteins, TolQ-TolR-TolA (linked to proton motive force) and two additional periplasmic proteins TolB and Pal. The p

The antiviral and immunomodulatory activity of deamidated cytokine was assessed using two precise and accurate cell-based assays. As expected, deamidated IFNβ-1a showed an increase in the bio

Abstract:

TNF defers apoptosis in macrophages undergoing spontaneous or pharmacologically (thapsigargin, ceramide, CCCP, etoposide or cisplatin)-induced apoptosis, as determined by measurements of caspase-3 activity and annexin-V staining (Chapter 2). The action requires TNF interaction with TNF-R1, not TNF-R2. Survival is uniquely reliant on the activity of the NF-B signaling pathway, and does not require activities arising from the PI3K/Akt, JNK, ERK, p38 MAP kinase or iNOS pathways (Chapter 3). Further, the general anti-apoptotic property of TNF and its specific antagonism of CCCP-induced apoptosis l

Natural products continue to be a major chemical lead matter for drug discovery due to their diverse chemical structures and bioactivities.

Combinatorial biosynthesis can be employed to modify existing chemical scaffolds towards reducing these limitations.

Abstract:

<p> <p>&nbsp<br></p> </p> <p align="left">This study utilized large-scale gene expression data to define the regulatory networks of genes expressing in the hippocampus to which multiple disease pathologies may be associated. Specific aims were: ident i fy key regulatory transcription factors (TFs) responsible for observed gene expression patterns, reconstruct transcription regulatory networks, and prioritize likely TFs responsible for anatomically restricted gene expression. Most of the analysis was restricted to the CA3 sub-region of Ammon&rsquo<br>s horn within the hippocampus. We identified

Abstract:

<p>Stress responsive genes play a key role in shaping the manner in which plants process and respond to environmental stress. Their gene products are linked to DNA transcription and its consequent translation into a response product. However, whilst these genes play a significant role in manufacturing responses to stressful stimuli, transcription factors coordinate access to these genes, specifically by accessing a gene&rsquo<br>s promoter region which houses transcription factor binding sites. Here transcriptional elements play a key role in mediating responses to environmental stress where e

Abstract:

<i>Salmonella</i> invasion protein C (SipC) and SipA bind actin directly. SipC inserts into the host cell plasma membrane from where it promotes effector delivery and is essential for <i>Salmonella</i> invasion. SipC-C (residues 200-409) directly nucleates actin polymerisation <i>in vitro</i> and induces cytoskeletal rearrangements at the leading edge when expressed in cells. By analysis a panel of SipC-C derivatives in transfected cells, a region spanning residues 377-409 was defined as necessary for actin reorganisation and leading-edge localisation. Residues 377-409 were sufficient to local
