  Several 16-dehidropregnenolone derivatives functionalized at C3, C4, C5 and C6 (Fig. 7) were prepared and evaluated as 5α-reductase inhibitors bearing in mind that after the formation of an enzyme-steroid complex a nucleophilic portion of the enzyme attacks the double bond of the steroid through Mic

  The 5α-reductase family is composed of three known isozymes, with the types I and II being the most known. Type I isozyme, which is the dominant form, can be found in the skin, liver, kidney, brain and lung. Furthermore, it has been evidenced that type I activity is several times higher in PC than i

  For the NSCLC patients with EGFR-activating mutations, EGFR-TKIs (gefitinib and erlotinib) are effective clinical therapies [21], [22]. However, approximately 10% of patients harboring EGFR-sensitizing mutations exhibit intrinsic resistance, and up to 40% do not attain a major response to treatment

  As previously mentioned when hypoxia-treated cells become re-oxygenated they sustain a significant amount of DNA damage which has been attributed to the formation of reactive oxygen species . This finding represents more than just an interesting in vitro phenomenon as within a tumor, cells have been

  Although TP53 status has been shown to play a role in ATR inhibition and platinum resistance [7], [27], [38], in inhibition of ATM and sensitivity to IR [39], and in the activation of Chk1 and Chk2 [3], [4], ATM and ATR signaling can occur through the p38MAPK/MK2 pathway in p53-deficient Fidaxomicin

  The mitogen-activated protein kinase (MAPK) plays an important role in a variety of cell processes by controlling transcriptional or translational regulation [14]. There are three major MAPK family members that have been well characterized: extracellular signal-regulated kinase (ERK), c-Jun N-termin

  As aforementioned, this study aimed to design, synthesize and investigate aromatase inhibitory and anti-breast cancer activities of N,N′-disubstituted thiourea derivatives. Based on the attractive phenotypic molecule 1, the synthetic N,N′-disubstituted thioureas have been designed including monothio

  It is now well established that the cumulative exposure to endogenous estrogens throughout a woman's life, mainly due to her reproductive history, has an impact on the risk of hormone-dependent breast cancer (Lambertini et al., 2016). Prolonged exposure to estrogens in the case of early age at menar

  Second, the choice of the PAABD is critical for an efficient and sensitive biosensor. The sequence of the PAABD should present high affinity and efficient recognition of the phosphorylated substrate, as opposed to poor affinity for the unphosphorylated substrate, and should display a fully reversibl

  In conclusion, there are only a few experimental reports evaluating the influence of melanin inhibitor on allergy. With the exception of studies using macrolides, most point to their harmful effect on the severity of this disease. Future studies will be crucial to define the impact of antibiotic use

  In the MT-SGL, two regularization parameters need to be specified: λ1 and λ2. Using recent results on norm regularization (Banerjee et al., 2014), it is possible to express both parameters via a single parameter as follows: and (Meier et al., 2008, Banerjee et al., 2014), where and are computed as:

  For patients who have taken advantage of the anti-TKIs and whose follow-up has been succeeded, some partial response has been noticed with 45% (9/20) for gefitinib, 39% (9/23) for erlotinib and 56.5% (13/23) for crizotinib. A disease progression has also been observed with 35% (7/20) for gefitinib,
