  2023-11-08

  

  A rational approach for the design of new steroid compounds as possible competitive inhibitors of CYP17 include chemical modification at C17 of the enzyme's natural substrates, pregnenolone (1) and progesterone (2), introducing groups with moderate to strong dipole properties at C20, such as oxime a

  2023-11-08

  

  Of note, core autophagy factors also play an important role during the infection of host cells by another type of picornavirus, namely, echovirus 7. ATG16L1 was found necessary for entry/internalization into Caco-2 polarized epithelial cells because the virus accumulated on the surface of ATG16L1-de

  Interestingly, this situation might be changed by the immunological context, in particular by the cytokines encountered during differentiation or activation. LPS-activation of bone marrow-derived DCs differentiated in GM-CSF decreases autophagy, CP2, and subsequent activation of CD4+ T cells (Fig. 2

  Introduction An association of elevated branched-chain RS 127445 HCl (BCAA—Leu, Val, Ile) with obesity and insulin resistance was first reported nearly 50 years ago (Felig et al., 1969). With the advent of metabolomics technologies, it has since become apparent that the association of BCAA and rela

  Apoptosis, a major process of programmed cell death, and in response to many chemopreventive agents (Jeyamohan et al., 2016). In general, two major signaling pathways control apoptosis, namely, a pathway mediated by cell death receptor and a pathway mediated by mitochondrion, and possible drug targe

  This development notwithstanding, the chemotherapeutic treatment for leukemia has stagnated over the last 40 years [35]. Main treatment options necessitate aggressive chemotherapy to target leukemic cells [36], [37], [38], [39]. Several limitations of current treatment options include the use of ant

  2023-11-07

  

  In human epidermoid carcinoma A431 cells, 12-lipoxygenase was significantly increased in glutathione-depleted cells. The relative abundance of phospholipid hydroperoxide versus glutathione peroxidase seems to play an important role in controlling the lipoxygenase reaction [57]. It has been proposed

  In eukaryotes, class III ACs (including GCs) are almost universally present, with the noteworthy exception of higher plants. Our dataset comprises 9690 sequences of class III nucleotide cyclases from 710 eukaryotic species. Approximately 80% thereof belong to subclass IIIa and 10% to subclasses IIIb

  The introduction of a pyrazole moiety into any position of the sterane core by cross-coupling reactions [13] or by Knorr construction from a CCC bis-electrophilic sterane precursor and an N,N binucleophile building block [17], [19] may serve as an example. Very few reports are to be found, however,

  Consistent with the observation that mutations in the redox-partner binding site of P450c17 that reverse charge from basic to acidic (R347H, R358Q) cause 17,20-lyase deficiency (Geller et al, 1997, Geller et al, 1999), at least one POR mutation that changes a residue in the FMN domain from neutral t

  Skeletal pain associated with bone fracture is another area of critical need for a novel pain medication. NSAIDs and opiates are the two major therapies currently used to manage bone fracture pain. However, both of these therapies lead to significant unwanted side effects. Using the osteotomy model

  Introduction Lung cancer is the leading cause of cancer death worldwide and is one of the most refractory of solid tumors along with pancreatic cancer. Since 1975 there have been notable improvements in the 5-year survival rate of patients with lung cancer [1]. This improvement in survival is tho

  The activity of MMPs is regulated at the level of gene transcription or by the enzymatic activation of latent enzymes. Inflammatory cytokines such as interleukin (IL)-1β, tumor necrosis factor (TNF)-α and IL-6 are elevated in synovial fluid, synovium and cartilage in patients with OA, and these cyto

  It is now thought that tight binding of HMGB to condensed chromatin may not be restricted to apoptotic cells. That HMGB proteins might actually be involved in the organization and/or maintenance of heterochromatic regions is suggested by the results of experiments analyzing the stable binding of the
