  E3 ubiquitin ligases are key players in the ubiquitin-proteasome pathway because they catalyse ubiquitination of substrate proteins.39, 40, 41 As important regulators of cellular ubiquitination, E3 ligases are emerging as attractive drug targets, particularly in cancer.42, 43, 44 However, E3 ligases

  Multi-subunit RINGs There are RING-type E3s that exist as multi-subunit assemblies (see Fig. 3B). A striking example is the Cullin RING Ligase (CRL) superfamily [35], which exhibits enormous plasticity in substrate specificity. Each CRL subfamily is characterized by a cullin protein (Cul-1, 2, 3,

  T cell infiltration is an important predictive biomarker for the PD-1 blockade, and it is closely associated with a good prognosis. In our study, we found that T cells were low and exhausted within the tumor microenvironment and were distributed in the tumor margin. Anti-PD-1 treatment reduced PD-1

  Stable isotope studies, applied to skeletal remains of early Pacific populations, have shown a trend toward a horticultural diet with temporal variation in response to local environmental conditions (Field et al., 2009; Kinaston and Buckley, 2013; Valentin et al., 2010, Valentin et al., 2014; Kinast

  Functional studies revealed that these ESR1 mutations lead to constitutive activity of the ER, meaning that the receptor is active in absence of estrogen, conferring resistance against several endocrine agents. Recent studies reported that the occurrence of ESR1 mutations is rare in ER+ primary brea

  Estrogens: Definition and history The term “estrogens” refers to a group of female hormones, including estrone, estradiol, estriol, and estretrol (Fig. 1). Chemically, estrogens belong to the family of organic compounds known as steroids. As such, their core structure is composed of 17 carbon-carbo

  Other pathways involved in the preventive and therapeutic potential of flavonoids in neurodegenerative diseases Rather than the induction of MAPK/ERK pathway, flavonoids actively modulate other critical intracellular neuronal survival and death protein kinases pathways, more importantly PI3K/Akt,

  Initial investigations in the heart uncovered Epac as a positive regulator of myocyte hypertrophy [8], [9]. Concomitantly, Epac has been shown to regulate cardiac Ca homeostasis [8], [10], [11], [12], [13]. Ca is an essential second messenger in the cardiac physiology because its rhythmic variations

  The action of 17-pt-PGE2 as an EP1 receptor agonist [34] was demonstrated in several experimental settings, including cancer, neurons, vascular system, kidney and was confirmed by application of EP1 receptor selective antagonists [35], [36], [37], [38], [39], [40], [41]. Receptor binding studies in

  Conclusions Mulan is a mitochondrial E3 ubiquitin ligase with diverse roles in cell growth, cell death, and mitophagy. To better understand the mechanism of Mulan\'s function we used a modified yeast two-hybrid system to isolate proteins that interact with its cytoplasmic RING domain (amino acids

  Discussion The regulation of intracellular cholesterol levels is a biological process of vital importance for cellular function and integrity, and involves robust transcriptional and post-transcriptional mechanisms that are sensitive to metabolic feedback control. Amongst post-transcriptional mec

  However, there are still some issues that remain poorly understood. For instance, how TGF-β modulates DDR2 expression and whether Smads participate in the regulation. How does DDR2 regulate the expression of PTHrP via Runx2? Is there any other kinase downstream of DDR2 participating in PTHrP regulat

  The data correlations from Multiflash™ [43] and DIPPR [44] were used for the liquid volume and heat of vaporization. For vapour pressure the curves were regressed from the experimental data present on both the DIPPR [44] and TRC [45] databases. As for liquid heat capacities both the latter databases

  Models and theories The CPA equation of state is composed predominantly of two parts: physical item and the association item based on the thermodynamic perturbation theory [21], [22], [26], [27]. The physical item is used to represent intermolecular physical interaction, usually representing the SR
