Cryopreservation induces transcriptomic and epigenetic modifications that strongly impairs sperm quality and function, and thus decrease reproductive performance. N
-methyladenosine (m
A) RNA methylation varies in response to stress and has been implicated in multiple important biological processes, including post-transcriptional fate of mRNA, metabolism, and apoptosis. This study aimed to explore whether cryopreservation induces m
A modification of mRNAs associated with sperm energy metabolism, cryoinjuries, and freezability.

The mRNA and protein expression of m
A modification enzymes were significantly dysregulated in sperm after cryopreservation. Furthermore, m
A peaks were mainly enriched in coding regions and near stop codons with classical RRACH motifs. Saracatinib The mRNAs containing highly methylated m
A peaks (fts vs. fs) were significantly associated with metabolism and gene expression, while the genes with less methylated m
A peaks were primarily involved in processes regulating RNA metabolism and transcription. Furthermore, the joint analysis of DMMGs and differentially expressed genes indicated that both of these play a vital role in sperm energy metabolism and apoptosis.

Our study is the first to reveal the dynamic m
A modification of mRNAs in boar sperm during cryopreservation. These epigenetic modifications may affect mRNA expression and are closely related to sperm motility, apoptosis, and metabolism, which will provide novel insights into understanding of the cryoinjuries or freezability of boar sperm during cryopreservation.

MicroRNA (miRNA) is a class of small noncoding RNAs, which targets on thousands of mRNA and thus plays important roles in many biological processes. It has been reported that miRNA has cross-species regulation functions between parasitoid-host, or plant-animal, etc. For example, several plant miRNAs enter into the honey bees and regulate gene expression. However, whether cross-species regulation function of miRNAs is a universal mechanism remains a debate question.

We have evaluated transmission of miRNAs from sunflower and sedr plants into the midgut of honey bee using RNA-Seq analyses complemented with confirmation by RT-qPCR. The results showed that at least 11 plant miRNAs were found in the midgut of honey bee feeding by sunflower and sedr pollen. Among which, nine miRNAs, including miR-30d, miR-143, miR-148a, miR-21, let-7 g, miR-26a, miR-126, miR-27a, and miR-203, were shared between the sunflower- and sedr-fed honey bees, suggesting they might have essential roles in plant-insect interactions. Moreover, existence of these co-shared miRNAs presents a strong evidence to support the successful transmission of miRNAs into the midgut of the insect. In total, 121 honeybee mRNAs were predicted to be the target of these 11 plant-derived miRNAs. Interestingly, a sedr-derived miRNA, miR-206, targets on 53 honeybee genes. Kyoto Encyclopedia of Genes and Genome (KEGG) analyses showed that these target genes are significantly involved in hippo signaling pathway-fly, Wnt signaling pathway, and N-Glycan biosynthesis.

In summary, these results provide evidence of cross-species regulation function of miRNA between honeybee and flowering host plants, extending our understanding of the molecular interactions between plants and animals.

The PSCs derived from livestock represents a more appropriate model than rodent for investigating human diseases due to their higher anatomical and physiological resemblance with human. Apart from that, livestock PSCs holds immense promises for the innovative therapies, transgenic animal production and their biomedical interest. The realization of the full potential of PSCs, however, depends on the elucidation of the molecular mechanisms which play a critical role in the maintenance of pluripotency and reprogramming procedure remains poorly understood in livestock which in turn impedes the generation of true PSCs and its usage for clinical research. An in-depth understanding of pluripotency is extremely essential for improving health and welfare of livestock animals. Therefore, present review focuses on the milestone achievements of PSCs in livestock animals and their potential application in health and production of livestock.
From time immemorial, natural products have been used for the treatment of various diseases. Various natural products, their semisynthetic derivatives, and synthetic analogs have been explored for their anti-infective properties. One such group of natural compounds that have been widely explored is manzamine alkaloids. Manzamine alkaloids are complex natural compounds consisting of a β-carboline nucleus attached to a pentacyclic ring system that was first isolated from a marine sponge during the 1980s.

The review aims to provide a critical overview of the anti-infective potential of manzamine alkaloids.

A comprehensive and exhaustive review of the literature on manzamine alkaloids consisting of their isolation, anti-infective properties, and mechanism of action is presented.

Various manzamine alkaloids have been isolated and found to exhibit potent anti-infective activities like antibacterial, antimalarial, antiviral, antifungal, antileishmanial, among others. These manzamine alkaloids exhibit their anti-infective activity by inhibiting targets like GSK-3β and MtSK.

This present review with structure-activity relationship study of manzamine alkaloids for their anti-infective activity will be useful for further development of semisynthetic manzamine analogs as potent anti-infective agents with better therapeutic potential and reduced toxicity.

In order to make progress in discovering the new agents for cancer treatment with improved properties and considering the fact that 3-hydroxy-3-pyrrolin-2-ones belong to a class of biologically active compounds, we tested series of eleven novels 1,5-diaryl-4-(2-thienylcarbonyl)-3-hydroxy-3-pyrrolin-2-ones for their antitumor potential.

All novel compounds were characterized by spectral (IR, NMR, MS) and elemental analysis. All novel 3-hydroxy-3-pyrrolin-2-ones were screened for their cytotoxic activity on two cancer cell lines, SW480 and MDA-MB 231, and non-transformed fibroblasts (MRC-5).

Compounds B8, B9, and B10 showed high cytotoxicity on SW480 cells together with good selectivity towards MRC-5 cells. It is important to empathize that the degree of selectivity of B8 and B10 was high (SI = 5.54 and 12.09, respectively). Besides, we explored the mechanisms of cytotoxicity of novel derivatives, B8, B9, and B10. The assay showed that tested derivatives induce an apoptotic type of cell death in SW480 cells, with a minor percent of necrotic cells. Additionally, to better understand the suitability of the compounds for potential use as anticancer medicaments, we studied their interactions with biomacromolecules (DNA or BSA). The results indicated that the tested compounds have a great affinity to displace EB from the EB-DNA complex through intercalation. Also, DNA and BSA molecular docking study was performed to predict the binding mode and the interaction region of the compounds.

Achieved results indicate that our compounds have the potential to become candidates for use as medicaments.

Many compounds containing a five-membered heterocyclic ring display exceptional chemical properties and versatile biological activities.

The objective of the present study was the desire to prepare the 5-substituted 2-amino-1,3,4-oxadiazole and 2-amino-1,3,4-thiadiazole derivatives and evaluate their potential anticancer, antibacterial and antifungal activities.

Twenty-seven derivatives were synthesized by iodine-mediated cyclization of semicarbazones or thiosemicarbazones obtained from condensation of semicarbazide or thiosemicarbazide and aldehydes. The structures were confirmed by 1H-NMR, 13C-NMR and MS spectra. The antibacterial and antifungal activities were evaluated by diffusion method and the anticancer activities were evaluated by MTT assay.

Twenty-seven derivatives have been synthesized in moderate to good yields. A number of derivatives exhibited potential antibacterial, antifungal and anticancer activities.

Compounds (1b, 1e and 1g) showed antibacterial activity against Streptococcus faed.General anesthetics depress excitatory and/or enhance inhibitory synaptic transmission principally by modulating the function of glutamatergic or GABAergic synapses, respectively, with relative anesthetic agent-specific mechanisms. Synaptic signaling proteins, including ligand- and voltage-gated ion channels, are targeted by general anesthetics to modulate various synaptic mechanisms including presynaptic neurotransmitter release, postsynaptic receptor signaling, and dendritic spine dynamics to produce their characteristic acute neurophysiological effects. As synaptic structure and plasticity mediate higher-order functions such as learning and memory, long-term synaptic dysfunction following anesthesia may lead to undesirable neurocognitive consequences depending on specific anesthetic agent and the vulnerability of population. Here we review the cellular and molecular mechanisms of transient and persistent general anesthetic alterations of synaptic transmission and plasticity.Almost two decades have passed since the last methamphetamine (METH) abuse epidemic. In recent years, METH abuse in the US has been rapidly increasing and is currently one of the leading causes of death in our country. Available statistical data indicates re-emergence of METH popularity and suggest an impending third epidemic of METH abuse. Alarmingly, there is no FDA- approved medication for METH use disorder (MUD). This disorder is currently treated with behavioral therapies; however, these therapies have limitations and would benefit from the addition of a MUD pharmacotherapy. Unfortunately, clinical trials have not yet found consistently effective pharmacotherapy for MUD. This review outlines the history of METH use, provides information on current prevalence of METH abuse and MUD, describes medications that have been in clinical trials for MUD, and addresses current as well as potential new treatments for MUD.
