Abstract The world is facing a new healthcare crisis with the rise and spread of novel coronavirus since December 2019. Also known as Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2), the disease associated with SARSCoV-2 is even called COVID-19. The infection is said to have originated from the bat community and transmitted to humans through an intermediate host (yet unknown) in Wuhan, in the Hubei region of China. COVID-19 is having a pulverizing impact on the scientific community. As of August 13, 2020, the number of confirmed cases had reached up to 20,439,814 and the death toll to 744,385, affecting more… More >

Abstract Mitochondria are important in eukaryotic cells due to their functions in energy production and regulation over other cellular activities. Oocytes are produced by a long and precisely controlled process, the dysfunction of which leads to impaired female fertility. As oocytes mature, mitochondria are constantly under the regulation of nuclear genes, the process of which can be modulated by extracellular signals. Understanding how nuclear genes regulate mitochondrial functions is important for studying animal reproduction and human fertility. As more and more genes regulating mitochondrial functions in oocytes are being revealed, new approaches for improving female fertility in both human and animals… More >

Abstract Melatonin, as a ubiquitous indoleamine hormone, is synthesized primarily by the pineal gland. It has diverse biological effects through quite complex mechanisms. More recently, studies have focused on the mechanism of melatonin in anti-reproductive toxicity/damage. Since melatonin possesses strong antioxidant and anti-apoptotic properties, researchers have examined its potential role in protecting against male reproductive toxicity/damage, which may be induced by chemotherapy or environmental toxicants and can lead to male infertility. In this article, recent progress regarding the protective effects of melatonin on male reproductive toxicity/damage is reviewed. More >

Abstract In vitro maturation (IVM), a promising assisted reproductive technology (ART), has been evolving in clinical trials and applications. There is a huge potential demand for IVM in clinical practice because it reduces the stimulation of gonadotropins to patients and provides evidence for the safety of neonatal birth. Unfortunately, the maturation rate of oocytes in vivo is not as high as it is in vivo due to a different microenvironment. Moreover, there are still controversies in predicting the developmental capability of oocytes in IVM. The granulosa cells (GCs) and cumulus cells (CCs), closely surrounding the oocytes, play a critical role in… More >

Abstract Temperature is a key regulator of brown adipose tissue (BAT) function, acting through central sensory inputs to influence metabolism and energy storage. Although animal models have produced a wealth of information on the pathways, effectors and responses mediating the physiological response of adipose tissue to temperature in vivo, the use of cell culture models now offers evidence of an additional cell-autonomous response to temperature changes, in the absence of neural input. In particular, stem cell models provide new insight into the regulation of adipogenic differentiation and the induction of browning features in vitro. Here the basis for adipogenic responsiveness to… More >

Abstract Preoperative chemoradiation therapy (CRT) is becoming the standard treatment for patients with locally advanced rectal cancer. However, individual differences in response to treatment range from a complete response to complete resistance. Predicting the tumor response to radiotherapy may improve the efficacy of radiotherapy. This review mainly summarizes recent studies about the molecular biomarkers that can predict the response to radiotherapy in rectal cancer. These studies have indicated that the molecular markers involved in the response to radiotherapy mainly include genes related to radiosensitivity, cancer stem cell-related markers, non-coding RNAs (ncRNAs), single-nucleotide polymorphisms (SNPs) and gene methylation, and other factors including… More >

Abstract Cancerous cells display abnormalities in the signal transduction pathways responsible for responding to extracellular growth factors, or mitogens. Mutations that alter proteins involved in these types of pathways can lead to inappropriate or unregulated cell growth, and therefore predispose the cell to become malignant. The critical role of the Ras/mitogen-activated protein kinase (MAPK) pathway in transducing growth signals to the interior of the cell and subsequently stimulating cell growth and proliferation is underscored by the fact that roughly one quarter of all human tumors contain mutant forms of Ras proteins. A particular focus on the signaling and membrane trafficking adaptor… More >

Abstract ULK1 (unc-51 like autophagy activating kinase 1), a mammalian serine/threonine kinase, is a key component of autophagy initiation complex and helps to induce all types of autophagy. Canonical autophagy is a process in which, through the interactions of a series of autophagy-related proteins, damaged organelles or misfolded proteins are engulfed by autophagosomes and then merged with lysosomes to be degraded. Thus, canonical autophagy is an important constituent part of the cellular “quality control.” Besides, accumulating evidence indicates that ULK1 exerts autophagy-independent effects in a cell-specific manner. For example, ULK1 facilitates neurite elongation through the regulation of endoplasmic reticulum (ER)–Golgi trafficking… More >

Abstract Antibody is an important part of adaptive immune system and is produced only by B cells. There are five main classes (IgM, IgD, IgG, IgA, IgE) and some subclasses in antibodies. IgM and IgD are produced by mature naïve B cells. On the other hand, IgG, IgA and IgE are produced by activated antigen-specific B cells via class switch recombination (CSR). CSR is the irreversible DNA rearrangement from upstream to downstream classes in immunoglobulin heavy chain genes. Co-stimulations of CD40 ligand (CD40L) and cytokines are required for induction of CSR by activating several transcription factors. These signal transduction pathways involve… More >

Abstract Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by abnormal cellular and humoral immune responses and excessive autoantibody production. The precise pathologic mechanism of SLE remains elusive. The advent of single-cell RNA sequencing (scRNA-seq) enables unbiased analysis of the molecular differences of cell populations at the single-cell level. We used scRNA-seq to profile the transcriptomes of peripheral blood mononuclear cells from an SLE patient compared with a healthy control (HC). A total of 16,021 cells were analyzed and partitioned into 12 distinct clusters. The marker genes of each cluster and the four major immune cell types (B cells,… More >

Abstract Sepsis, characterized as life-threatening sequential organ failure, is caused by a dysregulated host immune response to a pathogen. Conventional practice for sepsis is to control the inflammation source and administer highgrade antibiotics. However, the mortality rate of sepsis varies from 25–30% and can reach 50% if a septic shock occurs. In our current study, we used bioinformatics technology to detect immune status profiles in sepsis at the genomic level.

Abstract Randomly amplified polymorphic DNA (RAPD) is a tremendously convenient approach used to discriminate between Brassica species owing to its accuracy and speed. RAPD primers generate adequate genetic information that can be used in the primer-marker system. In this work, twenty RAPD-PCR based markers were executed to generate polymorphic data, like polymorphic information content (PIC), mean resolving power (MRP), resolving power (RP), effective multiplex ratio (EMR), and marker index (MI) for the first time and genetic distance among and between six Brassica species were calculated. Our results indicated that 20 primers produced a total of 231 scored band and generated 87%… More >

Abstract AP2/ERE-type transcription factors, as a type of plant-specific transcription factors, play a key role in plant biotic and abiotic stress. Meanwhile, they have been studied in many plants, but rarely in tomatoes. In this study, we performed a genome-wide analysis of the SlAP2/ERF gene family of tomato, and finally identified 29 SlAP2/ERF genes and divided them into different subfamilies. At the same time, its basic physical and chemical properties were analyzed. We also constructed phylogenetic trees with 30 Arabidopsis AP2/ERF proteins and 28 potatoes AP2/ERF proteins to ensure conservative homology between them. In addition, we mapped 29 SlAP2/ERF transcription factors… More >
