Eyes absent 1 (Eya1) is a conserved critical regulator of organ-specific stem cells. Ectopic Eya1 activities, however, promote transformation of mammary epithelial cells. Signals that instigate Eya1 oncogenic activities remain to be determined. Here, we show that Akt1 kinase physically

Although protein kinases and phosphatases have been reported to be involved in fear memory, information about these signalling molecules in the individual phases of contextual fear conditioning (cFC) is limited. C57BL/6J mice were tested in cFC, sacrificed and hippocampi were

Hesperetin (HSP, one of the most common flavonoids in Citrus) has been reported to possess many benificial effects and is indicated for many diseases both as a therapeutic drug and as a supplement. Although its vascular effects have been extensively

The cardiac isoform of troponin I (cTnI) has a unique 31-residue N-terminal region that binds cardiac troponin C (cTnC) to increase the calcium sensitivity of the sarcomere. The interaction can be abolished by cTnI phosphorylation at Ser22 and Ser23, an

Bacillus anthracis secretes the edema toxin (ET) that disrupts the cellular physiology of endothelial and immune cells, ultimately affecting the adherens junction integrity of blood vessels that in turn leads to edema. The effects of ET on the cytoskeleton, which

Ubiquitination is the first step of the ubiquitin-proteasome pathway that regulates cells for their homeostatic functions and is an enzymatic, protein post-translational modification process in which ubiquitin is transferred to a target protein substrate by a set of three ubiquitin

We cloned, overexpressed and purified Vibrio cholerae FtsZ protein for the first time. We used several complementary techniques to probe and compare the comparative assembly properties of recombinant Vibrio cholerae FtsZ (VcFtsZ) and Escherichia coli FtsZ (EcFtsZ). We observed that VcFtsZ

Although the contribution of Ca(2+) buffering systems can vary between neuronal types and cellular compartments, it is unknown whether distinct Ca(2+) sources within a neuron have different buffers. As individual Ca(2+) sources can have separate functions, we propose that each

A plethora of concurrent cellular activities is mobilised in the adaptation of plants to adverse environmental conditions. This response can be quantified by physiological experiments or metabolic profiling. The intention of this work is to reduce the number of metabolic

Replication timing is a crucial aspect of genome regulation that is strongly correlated with chromatin structure, gene expression, DNA repair, and genome evolution. Replication timing is determined by the timing of replication origin firing, which involves activation of MCM helicase

Cluster of differentiation (CD)69 is a leukocyte activation receptor involved in the maintenance of immune homeostasis and is positively selected in activated regulatory T (Treg) cells, implicating its role during Treg-cell differentiation. By RNA interference, we show that CD69 is

Accumulation of smooth muscle cells (SMC) results in neointima formation in injured vessels. Two graft models consisting of vein and artery grafts were created by anastomosing common carotid arteries to donor vessels. To identify the origin of the neointima cells

We reported previously that human translationally controlled tumor protein (TCTP) contains, at its NH2-terminus, a protein transduction domain (PTD), which we called TCTP-PTD, with the amino acid sequence MIIYRDLISH. In this report we describe how TCTP-PTD penetrates A549 human lung

We previously reported that bone morphogenetic protein 4/drosophila mothers against decapentaplegic protein (BMP4/Smad) signalling pathway initiated primordial follicle growth and prevented oocyte apoptosis via up-regulation of Sohlh2 and receptor for kit ligand (c-kit). The mechanism underlying this process was not

A major class of mechano-nociceptors to the intestine have mechanotransduction sites on extramural and intramural arteries and arterioles ('vascular afferents'). These sensory neurons can be activated by compression or axial stretch of vessels. Using isolated preparations we showed that increasing

Compensatory changes in energy expenditure occur in response to positive and negative energy balance, but the underlying mechanism remains unclear. Under low energy demand, the mitochondrial electron transport system is particularly sensitive to added energy supply (i.e. reductive stress), which

Hydroxysteroid (17β)-dehydrogenase type 1 (HSD17B1) catalyzes the conversion of low active 17-ketosteroids, androstenedione (A-dione) and estrone (E1) to highly active 17-hydroxysteroids, testosterone (T) and E2, respectively. In this study, the importance of HSD17B1 in ovarian estrogen production was determined using

Voltage-dependent calcium channels (VDCCs) are key elements in epileptogenesis. There are several binding-sites linked to calmodulin (CaM) and several potential CaM-dependent protein kinase II (CaMKII)-mediated phosphorylation sites in CaV1.2.

To date, many anticancer drugs have been developed by directly or indirectly targeting microtubules, which are involved in cell division. Although this approach has yielded many anticancer drugs, these drugs produce undesirable side effects. An alternative strategy is needed, and
