Comparative studies of X chromosomes in Cervidae family.

The family Cervidae is the second most diverse in the infraorder Pecora and is characterized by variability in the diploid chromosome numbers among species. X chromosomes in Cervidae evolved through complex chromosomal rearrangements of conserved segments within the chromosome, changes in centromere position, heterochromatic variation, and X-autosomal translocations. The family Cervidae consists of two subfamilies: Cervinae and Capreolinae.

Comparative Studies of Karyotypes in the Cervidae Family.

The family Cervidae is the second most diverse family in the infraorder Pecora and is characterized by a striking variability in the diploid chromosome numbers among species, ranging from 6 to 70. Chromosomal rearrangements in Cervidae have been studied in detail by chromosome painting. There are many comparative cytogenetic data for both subfamilies (Cervinae and Capreolinae) based on homologies with chromosomes of cattle and Chinese muntjac.

Relationship Between Elevated Hair Mercury Levels, Essential Element Status, and Metabolic Profile in Overweight and Obese Adults.

The objective of the present study was to evaluate hair essential and trace element levels and metabolic risk markers in overweight and obese subjects in relation to body mercury burden. According to 2 × 2 factorial design a total of 440 adults were distributed to four groups: (i) low-Hg normal-weight subjects (n = 114); (ii) high-Hg normal weight subjects (n = 113); (iii) low-Hg overweight (BMI > 25) subjects (n = 110); (iv) high-Hg overweight (BMI > 25) subjects (n = 110). Hg-exposed groups consisted of subjects characterized by frequent seafood consumption (> 4 times/week) subsequently evaluated by hair analysis (> 0.

Novel curcumin derivatives as P-glycoprotein inhibitors: Molecular modeling, synthesis and sensitization of multidrug resistant cells to doxorubicin.

The MDR1/P-glycoprotein (Pgp)/ABCB1 multidrug transporter is being investigated as a druggable target for antitumor therapy for decades. The natural product curcumin is known to provide an efficient scaffold for compounds capable of blocking Pgp mediated efflux and sensitization of multidrug resistant (MDR) cells to the Pgp transported drug doxorubicin (Dox). We performed molecular dynamics simulations and docking of curcumin derivatives into the Pgp model.

PF‑114, a novel selective inhibitor of BCR‑ABL tyrosine kinase, is a potent inducer of apoptosis in chronic myelogenous leukemia cells.

A t(9;22) chromosomal translocation which forms the chimeric tyrosine kinase breakpoint cluster region (BCR)‑Abelson murine leukemia viral oncogene homolog 1 (ABL) is a key mechanism underlying the pathogenesis of chronic myelogenous leukemia (CML). Pharmacological inhibition of BCR‑ABL with imatinib (Gleevec) has been reported as an effective targeted therapy; however, mutations (including the kinase domain of ABL) suppress the efficacy of inhibitors. PF‑114, a derivative of the third generation BCR‑ABL inhibitor ponatinib, demonstrated a high inhibitory activity against wild-type and mutant BCR‑ABL forms, such as the clinically important T315I.
