Metabolomics reveal root differential metabolites of different root-type alfalfa under drought stress.

Introduction: Alfalfa ( L.) is the favored premium feed ingredient in animal husbandry production which is in serious jeopardy due to soil moisture shortages. It is largely unknown how different root types of alfalfa respond to arid-induced stress in terms of metabolites and phytohormones.

Research insights into the chemokine-like factor (CKLF)-like MARVEL transmembrane domain-containing family (CMTM): their roles in various tumors.

The chemokine-like factor (CKLF)-like MARVEL transmembrane domain-containing (CMTM) family includes CMTM1-8 and CKLF, and they play key roles in the hematopoietic, immune, cardiovascular, and male reproductive systems, participating in the physiological functions, cancer, and other diseases associated with these systems. CMTM family members activate and chemoattract immune cells to affect the proliferation and invasion of tumor cells through a similar mechanism, the structural characteristics typical of chemokines and transmembrane 4 superfamily (TM4SF). In this review, we discuss each CMTM family member's chromosomal location, involved signaling pathways, expression patterns, and potential roles, and mechanisms of action in pancreatic, breast, gastric and liver cancers.

FOXM1 contributes to docetaxel resistance in castration-resistant prostate cancer by inducing AMPK/mTOR-mediated autophagy.

Docetaxel-mediated chemotherapy is the first line therapy for metastatic castration-resistant prostate cancer (CRPC) patients, but its therapeutic benefit is limited by the development of resistance. Although Forkhead box protein M1 (FOXM1) has been implicated in prostate tumorigenesis and metastasis, its role in docetaxel resistance has not been studied. Here, we showed that FOXM1 expression was upregulated in the docetaxel resistant CRPC cell lines (PC3-DR and VCaP-DR) and knockdown of FOXM1 sensitized the cells to docetaxel both in vitro and in vivo.

[Effects of Artesunate on hepatic fibrosis and its mechanism].

Objective: To investigate the effects of Artesunate(Art) on the LX-2 cell.

Methods: The cultured hepatic stellate cells were divided into control group and Art-treated groups with 250,350,450 µmol/L. The rate of cellular proliferation was detected by MIT assay, the content of ceramide (Cer)was determined by HPLC method, the content of hydroxyproline (Hyp) was determined by enzyme digestion method, the expressions of PPAR-γ, p53 and Caspase 3 were detected by Western blot.

[Effects of irrigation quota on moisture and salt redistribution in apple orchard soil in arid region].

Taking the salinized apple orchard soil in Qin'an County of Gansu Province, Northwest China as test object, a field experiment was conducted to study the effects of different irrigation quota (0, 900, 1800, 2700, and 3600 m3 x hm(-2)) on the redistribution of moisture and salt in 0-100 cm soil profile on the 10, 20, and 30 d during apple florescence stage. With the increase of irrigation quota, the leached depth of Na+ increased and its hysteretic effect of redistribution was more obvious, "the zero flux plane" of Ca2+ disappeared gradually, the scope of "the zero flux plane" of Mg2+ increased gradually, the leaching-migration mode of Cl- changed from "fluctuation" to "straight-line" and the evaporation-migration changed from "fluctuation" to "ladder", the redistribution pattern of SO4(2-) showed "point", and the position of redistribution and accumulation of HCO3- shifted gradually from the bottom to upper layer in soil profile. In the middle of the soil profile with deeper groundwater table, there existed a "zero flux plane" of salt, which shifted gradually from the upper layer to the bottom during the redistribution of moisture in soil profile, embodying the characteristics of moisture depletion in upland soils.

(Z)-4-[(Ethyl-amino)(furan-2-yl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.

In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol-ecules exist in the keto-enamine form. The pyrazole ring is oriented at 10.59 (4) and 57.

Poly[diaqua-(μ(3)-pyridine-3,5-dicarboxyl-ato-κN:O:O)copper(II)].

The title complex, [Cu(C(7)H(3)NO(4))(H(2)O)(2)](n), was prepared under hydro-thermal reaction conditions. In the crystal structure, the Cu(II) cation is located on a twofold rotation axis and is coordinated by two carboxyl-ate O atoms and one N atom from three pyridine-3,5-dicarboxyl-ate (PDA) anions and two water mol-ecules with a distorted trigonal-bipyramidal geometry. The tridentate PDA anion is also located on the twofold rotation axis and bridges the Cu(II) cations to form a two-dimensional polymeric layer.

4-(4-Chloro-phen-yl)-6-(methyl-sulfan-yl)pyrimidin-2-amine.

In the title compound, C(11)H(10)ClN(3)S, the dihedral angle between the benzene and pyrimidine rings is 3.99 (4)°. In the crystal, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into ribbons of R(2) (2)(8) rings parallel to [100].

Tris[2-(2-pyridylimino-meth-yl)phenol-ato(0.67-)]europium(III) nitrate.

The title compound, [Eu(C(12)H(9.33)N(2)O)(3)]NO(3), was obtained by the reaction of Eu(NO(3))·3H(2)O and the Schiff base ligand 2-(2-pyridylimino-meth-yl)phenol. The Eu atom is located on a threefold rotation axis and is nine-coordinated by three tridentate Schiff base ligands in a distorted tricapped trigonal-prismatic geometry.

In the title mononuclear complex, [Zn(N(3))(2)(C(8)H(8)N(6))(2)], the Zn(II) atom, lying on a twofold rotation axis, is six-coordinated in a distorted octa-hedral environment by four N atoms from two 2,4-diamino-6-(2-pyrid-yl)-1,3,5-triazine ligands and two N atoms from two end-on-coordinated azide ions. N-H⋯N hydrogen bonds between the ligand and azide ion link the complex mol-ecules into a three-dimensional network.
