Proteomic Analysis Reveals the Regulatory Role of Exogenous Gibberellin in Sugarcane Internode Maturation

ABSTRACT: Sugarcane cultivation is a vital component of the agricultural economy in southern China. Investigating internode development in sugarcane is crucial for optimizing cultivation management practices and improving cane yield. In this study, we performed an integrated analysis of the transcriptome and proteome to identify key molecular components and elucidate biological pathways involved in the internode development in sugarcane. Accordingly, exogenous gibberellin (GA) predominantly promoted internodal elongation, rather than nodal expansion. Following transcriptome and proteome sequencing, 3D principal component analysis (PCA) based on both datasets revealed a clear separation between the GA-treated and control groups.

Thermal proteome profiling and proteome analysis using high-definition mass spectrometry demonstrate modulation of cholesterol biosynthesis by next-generation galeterone analog VNPP433-3β in castration-resistant prostate cancer

Project description:Cholesterol (CHOL) homeostasis is significantly modulated in prostate cancer (PCa) suggesting an active role in PCa development and progression. Several studies indicate a strong correlation between elevated CHOL levels and increased PCa risk and severity. Inhibition of CHOL biosynthesis at different steps including lanosterol synthase (LSS) has shown significant efficacy against both hormone-dependent and castration-resistant PCa. Earlier, we reported proteasomal degradation of AR/AR-Vs and Mnk1/2 as the primary mechanisms of action of VNPP433-3β in inhibiting PCa cell proliferation and tumor growth. Through thermal proteome profiling, comparative proteomics and cellular thermal shift assay, we identified VNPP433-3β's ancillary effect of lowering CHOL by binding to LSS and lanosterol 14-alpha demethylase, potentially inhibiting CHOL biosynthesis in PCa cells and tumors. Additionally, in conjunction with our previously reported transcriptome analysis, proteomics reveals that VNPP433-3β modulated upstream regulators and pathways critical for PCa stem cell maintenance and recurrence. The inhibition of CHOL biosynthesis by VNPP433-3β reinforces its multifaceted effects in PCa across all stages, highlighting its potential as a single-agent therapy. Achieving reduced CHOL levels aligns with better treatment outcomes, further substantiating VNPP433-3β’s therapeutic potential.

Vitrification preserves oocyte transcriptome in a 3D in vitro follicle development and oocyte maturation system

Project description:Vitrification is increasingly used to cryopreserve gametes and embryos in assisted reproductive technology (ART). Our prior research demonstrates that vitrification preserves the viability and functionality of ovarian follicles. However, its impact on follicle-enclosed oocyte remains unknown. The current study investigates whether vitrification, combined with a 3D encapsulated in vitro follicle growth (eIVFG) system, maintains oocyte transcriptome during in vitro follicle development and oocyte maturation. Immature mouse preantral follicles were vitrified and cultured in eIVFG for 8 days to grow to the preovulatory stage, followed with the induction of ovulation and oocyte maturation on day 9, with fresh follicles as the control. Oocytes at germinal vesicle (GV) stage from grown preovulatory follicles on day 8 and oocytes at metaphase II (MII) upon ovulation on day 9 were collected for single-oocyte Smart-Seq2 RNA sequencing analysis. The principal component analysis (PCA) separated GV and MII oocytes into two distinct clusters, but oocytes from fresh and vitrified follicles were largely overlapped. Differential gene expression (DEG) analysis revealed that GV or MII oocytes from fresh and vitrified follicles had comparable expression of maternal effect genes and other genes related to oocyte meiotic and developmental competence. There was a significant transcriptomic change during the GV-to-MII transition. Gene ontology (GO) and KEGG analysis identified DEGs between GV and MII oocytes related to cell cycle, RNA processing, mitochondria, and ribosome. In summary, our study demonstrates that vitrification preserves oocyte transcriptome during in vitro follicle development and oocyte maturation, supporting its potential in fertility preservation. Moreover, our single-oocyte RNA sequencing analysis identifies key DEGs upon GV-to-MII transition, indicating their potential functions in underpinning oocyte meiotic and developmental competence.

RUNX2 selectively attenuates or augments androgen-driven transcription in prostate cancer

Project description:Prostate carcinogenesis is associated with changes in androgen signaling from driving cellular differentiation to promoting oncogenic behaviors. RUNX2 binds the androgen receptor (AR), and ectopic expression of RUNX2 is linked to prostate cancer (PCa) progression. We therefore investigated genome-wide the influence of RUNX2 on androgen-induced gene expression and AR DNA binding in PCa cells. The predominant function of RUNX2 is to inhibit the androgen response, attributable in part to dissociation of AR from target genes such as the tumor suppressor NKX3-1. At a minority of AR target genes, however, AR activity persists in the presence of RUNX2. Some of these genes are co-operatively stimulated by androgen and RUNX2 signaling and are characterized by the presence of putative enhancers co-occupied by AR and RUNX2. Genes synergistically stimulated by AR and RUNX2 include the invasion-promoting transcription factor SNAI2. Indeed, co-activation of AR and RUNX2, but neither alone, stimulated PCa cell invasiveness, which was abolished by SNAI2 silencing. Accordingly, PCa biopsies most strongly stained for SNAI2 exhibit high nuclear expression of both RUNX2 and AR. The RUNX2-mediated locus-dependent modulation of AR activity in PCa opens a research avenue that may guide the development of novel diagnostic and therapeutic approaches to patient management. total RNA from C4-2B/Rx2dox cells was extracted in biological triplicates from four different conditions. Ethanol vehicle control, dox to induce RUNX2 expression, DHT to activate androgen receptor and DHT+dox combined.

A PROSTATE TUMORGRAFT PANEL TO ACCELERATE PRECISION MEDICINE

Project description:The management of advanced prostate cancer (PCa) has strongly evolved in the last decade with the introduction of the next generation of androgen receptor pathway inhibitors which have considerably improved patient outcomes. Most recently, the investigation of genomic landscape has provided targetable molecular alterations such as homologous gene DNA repair defects correlated with response to PARP inhibitors. Despite these significant advances, while localized PCa is generally associated with favorable outcome, metastatic PCa is currently considered incurable. For further investigations in precision treatment, the development of preclinical models representing the complex prostate tumor heterogeneity are mandatory. Accordingly, we aimed to establish a resource of patient-derived xenograft (PDX) models that exemplify each phase of this multistage disease for accurate and rapid evaluation of candidate therapies.

Palmitoyl acyltransferase ZDHHC7 suppresses prostate cancer through inhibiting androgen receptor expression

Project description:We examined ZDHHC family gene expression in human tissue collection and identified ZDHHC7 as a PCa-relevant member. RNA-seq analyses of PCa cells with ZDHHC7 de-regulation revealed global alterations in androgen response and cell cycle pathways. Mechanistically, ZDHHC7 inhibits AR gene transcription and therefore reduces AR protein levels and abolishes AR signaling in PCa cells. Accordingly, ZDHHC7 depletion increased oncogenic properties of PCa cells, whereas restoring ZDHHC7 is sufficient to suppress PCa cell proliferation and invasion in vitro and mitigate xenograft tumor growth in vivo. Lastly, we demonstrated that ZDHHC7 is down-regulated in human PCa compared to benign adjacent tissues and its loss is associated with worse clinical outcomes. Taken together, our findings unequivocally prove ZDHHC7 as a tumor suppressor gene that inhibits AR signaling and PCa progression, identifying ZDHHC7 loss as a biomarker for aggressive PCa and a target for therapeutic intervention.

Transcriptome analysis of Gibberellin-response gene in the fast-growing species moso Bamboo

Project description:Moso bamboo is well known with its rapid growth rate. In order to shed light on the underlying mechanism of growth, we applied Gibberellin (GA) to mimic the fast development process in bamboo and found that exogenous GA can significantly increase the length of internode of moso bamboo. Subsequently, we sequenced the transcriptome by high-through sequencing and identified 5,148 different expressed genes (DEG) and find out 22 genes that take part in GA signaling pathway is significantly differently expressed, including GID1A, GID1B and GAI. From GO analysis, a group of genes related to response hormone stimulus are enriched in up-regulated DEGs and 178 GA-responded genes are involved in other plant hormone signaling pathway, of which genes MYB74 and NCED5 are belong to both two pathways. Besides, clusters of genes about photosynthesis are enriched in down-regulated DEGs. By looking into the content of chlorophyll, we find out that the concentrations of chlorophyll are obviously decreased which verify that photosynthesis do weakened after GA treatment. Through method of slicing by hand, it appears that an increased condensation of lignin after GA treatment. The results imply a functional role of GA in bamboo growth, and maybe major in cell wall formation, and photosynthesis. Differential AS alternative splicing (AS) events upons GA induce suggested that post-transcriptional regulation is involved in the GA response.

Transcriptome and metabolome analyses reveal the regulatory network governing red fruitbody disease in Morchella

Project description:True morels (Morchella spp., Morchellaceae, Ascomycota), a delicious edible mushroom, has rapidly expanded in recent years, especially in China. However, a severe disease of morels, red fruitbody disease, led to very low production of fruiting bodies. The cause reason and the mechanisms under red fruitbody are unclear. Herein, we integrated the transcriptomics and metabolomics data of M. sextelata from red fruitbody group (R) and normal group (N), which was artificial cultivation in Fujian province, China. Transcriptome data revealed the differentially expressed genes (DEGs) between R group and N group were significantly enriched in the pathways of tyrosine metabolism, riboflavin metabolism, and glycerophospholipid metabolism. Similarly, the differential accumulated metabolites (DAMs) were mainly assigned to metabolism categories, including tyrosine metabolism, biosynthesis of plant secondary metabolites, biosynthesis of amino acids, and others. Then, combined analysis of the transcriptome data and metabolome traits revealed that the most enriched pathway was tyrosine metabolism, followed by ABC transporters, alanine, aspartate and glutamate metabolism, and others. In summary, this integration of transcriptomics and metabolomics data of M. sextelata during fruitbody redness implicated several key genes, metabolites, and pathways involved in this disease. We believe that these findings will help us understand the mechanisms under fruitbody redness of M. sextelata and provide new clues for optimizing the methods for its cultivation application.
