[PMID: 38816350 PMCID: PMC11141472 DOI: 10.1080/15384047.2024.2360768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 05/23/2024] [Indexed: 06/01/2024] Open
Abstract
Circular RNA Ribonuclease P RNA Component H1 (circ_RPPH1) and microRNA (miRNA) miR-1296-5p play a crucial role in breast cancer (BC), but the molecular mechanism is vague. Evidence showed that miR-1296-5p can activate tripartite motif-containing 14 (TRIM14). Clinical indications of eighty BC patients were collected and the circ_RPPH1 expression was detected using real-time quantitative PCR. MCF-7 and MDA-MB-231 cells were transfected with overexpression or knockdown of circ_RPPH1, miR-1296-5p, or TRIM14. Cell counting kit-8, cell cloning formation, wound healing, Transwell, and flow cytometry assays were performed to investigate the malignant phenotype of BC. The dual-luciferase reporter gene analyses were applied to reveal the interaction between these target genes. Subcutaneous tumorigenic model mice were established with circ_RPPH1 overexpression MDA-MB-231 cells in vivo; the tumor weight and volume, levels of miR-1296-5 and TRIM14 mRNA were measured. Western blot and immunohistochemistry were used to detect TRIM14 in cells and mice. Circ_RPPH1 levels were notably higher in BC patients and have been found to promote cell proliferation, invasion, and migration of BC cells. Circ_RPPH1 altered cell cycle and hindered apoptosis. Circ_RPPH1 knockdown or miR-1296-5p overexpression inhibited the malignant phenotype of BC. Furthermore, miR-1296-5p knockdown reversed circ_RPPH1's promotion effects on BC. Interestingly, TRIM14 overexpression counteracts the inhibitory effects of miR-1296-5p overexpression and circ_RPPH1 silencing on BC. Moreover, in BC tumor-bearing mice, circ_RPPH1 overexpression led to increased TRIM14 expression and facilitated tumor growth. Circ_RPPH1 enhanced BC progression through miR-1296-5p/TRIM14 axis, indicating its potential as a biomarker and therapeutic target in BC.

Abstract
Gastric cancer (GC) is 4th in incidence and mortality rates globally. Several genetic and epigenetic factors, including microRNAs (miRNAs), affect its initiation and progression. miRNAs are short chains of nucleic acids that can regulate several cellular processes by controlling their gene expression. So, dysregulation of miRNAs expressions is associated with GC initiation, progression, invasion capacity, apoptosis evasions, angiogenesis, promotion and EMT enhancement. Of important pathways in GC and controlled by miRNAs are Wnt/β-catenin signaling, HMGA2/mTOR/P-gp, PI3K/AKT/c-Myc, VEGFR and TGFb signaling. Hence, this review was conducted to review an updated view of the role of miRNAs in GC pathogenesis and their modulatory effects on responses to different GC treatment modalities.

Abstract
Gastric cancer predominantly occurs in adenocarcinoma form and is characterized by uncontrolled growth and metastases of gastric epithelial cells. The growth of gastric cells is regulated by the action of several major cell cycle regulators including Cyclins and Cyclin-dependent kinases (CDKs), which act sequentially to modulate the life cycle of a living cell. It has been reported that inadequate or over-activity of these molecules leads to disturbances in cell cycle dynamics, which consequently results in gastric cancer development. Manny studies have reported the key roles of Cyclins and CDKs in the development and progression of the disease in either in vitro cell culture studies or in vivo models. We aimed to compile the evidence of molecules acting as regulators of both Cyclins and CDKs, i.e., upstream regulators either activating or inhibiting Cyclins and CDKs. The review entails an introduction to gastric cancer, along with an overview of the involvement of cell cycle regulation and focused on the regulation of various Cyclins and CDKs in gastric cancer. It can act as an extensive resource for developing new hypotheses for future studies.

Abstract
Papillary thyroid carcinoma (PTC) has a favorable prognosis, but a fraction of cases show progressive behaviors, becoming radioiodine refractory (RAIR) PTC. To explore circulating exosomal microRNAs (miRNAs) associated with RAIR PTC, the miRNA profiles in exosomes from parental and induced RAIR cell lines were firstly identified with a next-generation sequencing technique. The Na+/I- symporter (NIS) related miRNAs were then validated by quantitative real-time PCR (qRT-PCR) in plasma of PTC patients with non-131I-avid metastases and those with 131I-avid metastases. The regulation of exosomal miRNAs on NIS were also verified. We identified that miR-1296-5p, upregulation in exosomes from RAIR cell lines, and the plasma of patients with RAIR PTC achieved the largest areas under the curve (AUC) of 0.911 and that it is an independent risk factor for RAIR PTC. In addition, miR-1296-5p was abundantly detected in the tissue of RAIR PTC and can directly target downstream gene of NIS. Taken together, our findings suggested that circulating exosomal miRNAs, particularly miR-1296-5p, may be involved in the pathogenesis of RAIR PTC by directly targeting NIS.

Abstract
Epithelial growth factor receptor (EGFR), a transmembrane receptor on the cell surface, carries extracellular messages into the cell and alters the activity of the nucleus through tyrosine signalling. EGFR-targeted treatments have influenced the new era of precision oncology throughout the last few decades. Despite significant progress, long-term remission from solid tumours is still a distant goal for many oncologists. There are several methods by which tumour cells alter the activity of this protein in solid tumours. EGFR-related oncogenic pathways, resistance mechanisms, and novel avenues to suppress tumour development and metastatic spread were discovered in clinical specimens using preclinical models (cell cultures, xenografts, mouse models), which were then validated in those specimens. EGFR has been implicated in the onset and advancement of a variety of cancers, according to research. An overview of EGFR's structural anatomy and physiology, its role in cancers, and clinical studies that target EGFR in various tumours are included in this review.

Abstract
Background Long non-coding RNAs (lncRNAs) are essential regulators of tumorigenesis and the development of colorectal cancer (CRC). Here, we aimed to investigate the role of lncRNA GAS6-AS1 in CRC and its potential mechanisms. Methods Bioinformatics analyses evaluated the level of GAS6-AS1 in colon cancer, its correlation with clinicopathological factors, survival curve and diagnostic value. qRT-PCR were performed to detect the GAS6-AS1 level in CRC samples and cell lines. The CCK8, EdU, scratch healing, transwell assays and animal experiments were conducted to investigate the function of GAS6-AS1 in CRC. RNA immunoprecipitation (RIP) and dual-luciferase reporter gene analyses were carried out to reveal interaction between GAS6-AS1, TRIM14, FUS, and miR-370-3p/miR-1296-5p. Results GAS6-AS1 was greatly elevated in CRC and positively associated with unfavorable prognosis of CRC patients. Functionally, GAS6-AS1 positively regulates CRC proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) in vitro and induces CRC growth and metastasis in vivo. Moreover, GAS6-AS1 exerted oncogenic function by competitively binding to miR-370-3p and miR-1296-5p, thereby upregulating TRIM14. Furthermore, we verified that GAS6-AS1 and TRIM14 both interact with FUS and that GAS6-AS1 stabilized TRIM14 mRNA by recruiting FUS. Besides, rescue experiments furtherly demonstrated that GAS6-AS1 facilitate progression of CRC by regulating TRIM14. Conclusion Collectively, these findings demonstrate that GAS6-AS1 promotes TRIM14-mediated cell proliferation, migration, invasion, and EMT of CRC via ceRNA network and FUS-dependent manner, suggesting that GAS6-AS1 could be utilized as a novel biomarker and therapeutic target for CRC.

Abstract
BACKGROUND Glioma is the most common primary intracranial tumor. It is notorious for its high degree of malignancy, strong invasion, and poor prognosis. The transmembrane emp24 trafficking protein 3 (TMED3) belongs to the TMED family, which is responsible for intracellular protein transport and innate immune signal transmission. More and more evidence shows that TMED3 plays a key role in the tumor progression of human cancer. However, the role and potential molecular mechanism of TMED3 in glioma have not been clarified. METHODS TMED3 expression levels, clinical data, survival prognosis, prediction of upstream miRNA, and immune-related analyses were all analyzed utilizing relevant databases. Finally, a molecular cell experiment confirmed TMED3 expression in glioma. RESULTS We discovered that TMED3 is overexpressed in most tumors, including gliomas, and is associated with tumor staging and prognosis. Subsequently, a combination of a series of bioinformatics analyses, including correlation and survival analyses, identified miR-1296-5p as the most potent upstream miRNA of TMED3 in gliomas.Additionally, we analyzed the relationship between TMED3 level and tumor immune cell infiltration and immune checkpoint expression. CONCLUSION TMED3 is highly expressed in gliomas and is associated with tumor staging and affects the prognosis of patients. Therefore, the TMED3 gene may be a potential immunotherapy target and prognostic marker for gliomas.

Abstract
Cisplatin (DDP)-induced chemoresistance is an important reason for the failure of non-small cell lung cancer (NSCLC) treatment. Circular RNAs (circRNAs) participate in the chemoresistance of diverse cancers. However, the function of hsa_circ_0017639 (circ_0017639) in the DDP resistance of NSCLC is unclear. Forty-one NSCLC samples (21 DDP-resistant samples and 20 DDP-sensitive samples) were utilized in the research. The relative expression levels of some genes were determined by real-time quantitative polymerase chain reaction (RT-qPCR). 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay for half-maximal inhibitory concentration (IC50) value of DDP and cell viability, colony formation and 5-ethynyl-2’-deoxyuridine (EDU) assays for cell proliferation, flow cytometry assay for cell apoptosis, transwell assay for cell invasion and wound-healing assay for cell migration were performed. The regulation mechanism of circ_0017639 was demonstrated by a dual-luciferase reporter assay. We observed higher levels of circ_0017639 in DDP-resistant NSCLC samples and cells. Functionally, circ_0017639 silencing decreased tumor growth and elevated DDP sensitivity in vivo and induced apoptosis, repressed proliferation, invasion, and migration of DDP-resistant NSCLC cells in vitro. Mechanically, circ_0017639 modulated sine oculis homeobox 1 (SIX1) expression via sponging microRNA (miR)-1296-5p. Also, miR-1296-5p inhibitor restored circ_0017639 knockdown-mediated impacts on cell DDP resistance in DDP-resistant NSCLCs. Furthermore, SIX1 overexpression counteracted the inhibiting impact of miR-1296-5p upregulation on DDP resistance and malignant phenotypes of DDP-resistant NSCLC cells. In conclusion, circ_0017639 conferred DDP resistance and promoted tumor growth via elevating SIX1 expression through sequestering miR-1296-5p in NSCLC, providing a new mechanism for understanding the chemoresistance and progression of NSCLC.

Abstract
Breast cancer (BC) is one of the leading causes of cancer-related deaths in female. Circular RNA (circRNA), as reported, is involved in the progression of BC. This work focuses on clarifying the biological function of circ_0048764 in BC and its hidden mechanism. Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to detect the expressions of circ_0048764, microRNA-1296-5p (miR-1296-5p), and tripartite motif containing 14 (TRIM14) in BC tissues and cell lines. Besides, the status of proliferation, migration, invasion and apoptosis of BC cells was probed by cell counting kit-8 (CCK-8), EdU, transwell and flow cytometry assays. Western blot was adopted to examine the level of TRIM14 protein in BC cells. In addition, dual-luciferase reporter gene assay and RNA immunoprecipitation (RIP) assay were conducted to corroborate the targeting relationships between miR-1296-5p and circ_0048764 or TRIM14. It was revealed that circ_0048764 expression was remarkably up-regulated in BC tissues and cells, and circ_0048764 expression was associated with TNM stage and tumor size. Functionally, overexpression of circ_0048764 significantly promoted BC cell proliferative, migrative and invasive abilities and inhibited apoptosis, while circ_0048764 knockdown exerted the opposite effects. Mechanistically, circ_0048764 directly targeted miR-1296-5p and could negatively modulate its expression in BC cells. Besides, miR-1296-5p could reverse the influence of circ_0048764 on BC viability, migration, invasion and apoptosis. Moreover, TRIM14 was confirmed to be a downstream target of miR-1296-5p. Circ_0048764 positively regulated TRIM14 expression in BC cells via targeting miR-1296-5p. Collectively, it is concluded that circ_0048764 promotes the development of BC via modulating the miR-1296-5p/TRIM14 axis.

Abstract
Background Triple‐negative breast cancer (TNBC) is the most aggressive subtype of breast cancer with a high incidence of local recurrence and metastasis. Circular RNAs (circRNAs) are implicated in the pathomechanism of TNBC. Here, we investigated the function of circ_0000520 in TNBC and its associated mechanism. Methods Reverse transcription quantitative polymerase chain reaction (RT‐qPCR) and Western blot assay were used to measure RNA and protein expression. Cell proliferation was analyzed by cell counting kit‐8 (CCK8) assay, flow cytometry and colony formation assay. Cell apoptosis was assessed by flow cytometry. Cell migration ability was analyzed by transwell migration and wound healing assays. Transwell invasion assay was conducted to analyze the invasion ability. Dual‐luciferase reporter assay, RNA immunoprecipitation (RIP) assay, and RNA‐pulldown assay were performed to verify the interaction between microRNA‐1296 (miR‐1296) and circ_0000520 or zinc finger protein X‐linked (ZFX). Xenograft mice model was established to analyze the role of circ_0000520 in xenograft tumor growth in vivo. Results Circ_0000520 expression was upregulated in TNBC tissues and cell lines. Circ_0000520 knockdown suppressed the proliferation, migration, and invasion whereas induced the apoptosis of TNBC cells. miR‐1296 was verified as a target of circ_0000520, and circ_0000520 silencing‐mediated suppressive effects on the malignant potential of TNBC cells were partly overturned by miR‐1296 knockdown. miR‐1296 interacted with the 3′ untranslated region (3′UTR) of ZFX, and ZFX overexpression partly reversed miR‐1296 overexpression‐mediated effects in TNBC cells. Circ_0000520 absence reduced ZFX expression by upregulating miR‐1296 in TNBC cells. Circ_0000520 silencing suppressed xenograft tumor growth in vivo. Conclusions Circ_0000520 contributed to TNBC development by binding to miR‐1296 to induce ZFX expression.

Abstract
Aberrant expression of microRNAs (miRNAs) has been reported to play a role in tumorigenesis. Dysfunction of miR-1296 was found in a variety of cancers, however, the function of miR-1296 in the progression of glioma remains largely understood. Here, our results showed that miR-1296 was significantly down-regulated in glioma tissues and cell lines. Decreased expression of miR-1296 was associated with the tumor size, WHO grade and karnofsky performance scale (KPS) of glioma patients. Low expression of miR-1296 was significantly correlated with the shorter 5-year overall survival of glioma patients. Overexpression of miR-1296 inhibited the proliferation, colony formation, migration and induced apoptosis of glioma cells. MiR-1296 was found to bind the 3’-untranslated region (UTR) of ABL proto-oncogene 2 (ABL2) and subsequently repressed both the mRNA and protein expression of ABL2. ABL2 was overexpressed in glioma tissues and inversely correlated with that of miR-1296. Ectopic expressed ABL2 could reverse the inhibitory effects of miR-1296 on glioma cell proliferation. Our results illustrated the novel tumor-suppressive function of miR-1296 in glioma via repressing ABL2, suggesting a potential application of miR-1296 in the treatment of glioma.

CDK6 is stimulated by hyperthermia and protects gastric cancer cells from hyperthermia‑induced damage. Mol Med Rep 2021; 23:240. [PMID: 33537819 PMCID: PMC7893798 DOI: 10.3892/mmr.2021.11879] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Accepted: 12/15/2020] [Indexed: 12/17/2022] Open
Abstract
Hyperthermia is one of the most widely employed adjuvant treatments for cancer, especially for hyperthermic intraperitoneal chemotherapy, and has few side effects. Gastric cancer has various hyperthermia sensitivities, but the exact molecular mechanisms remain to be elucidated. In the present study, western blotting was performed to detect differential expression of proteins that have been reported to be upregulated in gastric cancer. Following knockdown of these proteins, apoptosis was measured by Annexin V-FITC/propidium iodide (PI) double staining and hyperthermia treatment was applied. To evaluate the effect of cyclin-dependent kinase 6 (CDK6) on hyperthermia-induced apoptosis, CDK6 was knocked down or inhibited by the addition of a specific inhibitor and subsequent PI staining and cell proliferation, migration and invasion assays were performed. Hyperthermia-induced protein kinase B (AKT) expression and phosphorylation inhibition were detected. As demonstrated in the present study, the hyperthermia-induced proteins kinesin family member 11 (KIF11), cyclin-dependent kinase 6 (CDK6), stromal antigen 2, NIMA-related kinase 2 and karyopherin subunit α 4 were highly expressed in gastric cancer cells, including SH-10-TC and HGC-27 cells. Knockdown of KIF11 significantly increased apoptosis without hyperthermia treatment and CDK6 significantly increased hyperthermia-induced apoptosis, prompting the present study to focus on CDK6. It was further confirmed that CDK6 activity was critical for decreasing hyperthermia-induced apoptosis and for cell proliferation. Hyperthermia-induced AKT expression and phosphorylation inhibition is potentially the main cause of CDK6 transcriptional upregulation. Taken together, these findings demonstrated that CDK6 is upregulated via hyperthermia-induced AKT inhibition and subsequently protected gastric cancer cells from hyperthermia-induced apoptosis, indicating that it is a potential therapeutic target to sensitize gastric cancer cells to hyperthermia-based therapy.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common causes of cancer death. GSE83521 microarray analysis suggested that circular RNA circ_ASAP2 (hsa_circ_0008768) expression was increased in GC tissues. However, the molecular mechanism of circ_ASAP2 remains unknown. METHODS Expression levels of circ_ASAP2, microRNA-770-5p (miR-770-5p), and the cyclin-dependent kinase 6 (CDK6) were detected by using real time PCR (RT-PCR). 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and transwell assays were applied to explore cell viability, migration, and invasion, respectively. The interactions between miR-770-5p and circ_ASAP2 or CDK6 was predicted by using Starbase software, and then confirmed by luciferase reporter assay. Xenograft tumor model was also used to estimate the effect of circ_ASAP2 on tumor growth in vivo. RESULTS The expression levels of circ_ASAP2 and CDK6 were increased, and miR-770-5p level was decreased in GC tissues and cells. Furthermore, circ_ASAP2 knockdown inhibited cell viability, migration, and invasion of GC cells. Mechanically, circ_ASAP2 functioned as a sponge of miR-770-5p to regulate CDK6 expression, thereby boosting the progression of GC cells. Circ_ASAP2 silencing hindered the tumor growth of GC in vivo. CONCLUSION Circ_ASAP2 knockdown can repress the development of GC cells partly through regulating the miR-770-5p/CDK6 axis, suggesting an underlying circRNA-targeted therapy for GC treatment.

Abstract
Background: To investigate the mechanism of microRNA9 in inhibiting proliferation and migration of lung squamous cell carcinoma cells via neuron-restricted silencing factor/epidermal growth factor receptor. Material and Methods: Detection of microRNA9, neuron-restricted silencing factor, and epidermal growth factor receptor expression levels in lung cancer patients’ tissues and lung cancer cells by Western blotting and quantitative polymerase chain reaction. Detection of cell proliferation by colony formation assay and cell counting kit-8 assay. Detection of cell migration by wound-healing assay and Transwell assay. And detection of the regulatory effect between neuron-restricted silencing factor and epidermal growth factor receptor by Luciferase reporter gene system. Subcutaneous implantation mouse models of NCI-H520 cells were constructed to detect cell proliferation in vivo, and Kaplan–Meier method calculated patient survival. Results: The expression of microRNA9 and epidermal growth factor receptor was higher in lung cancer tissues than in normal lung tissues, while the expression of neuron-restricted silencing factor was lower in lung cancer tissues than in normal lung tissues. MicroRNA9 higher expression was strongly related to tumor size, and TNM stage and predicted showed reduced overall survival in patients with lung cancer. Further loss of function and enhancement experiments revealed that inhibition of microRNA9 could significantly inhibit lung squamous carcinoma cell proliferation and migration. Luciferase reporter assay demonstrated that microRNA9 could bind to NRSF messenger RNA and inhibit its expression, neuron-restricted silencing factor overexpression also exerted inhibitory effects on cell proliferation and migration. Moreover, Luciferase reporter assay showed that neuron-restricted silencing factor downregulate epidermal growth factor receptor expression levels by binding to epidermal growth factor receptor promoter regions, and Pearson’s correlation analysis indicated that the levels of microRNA9 in lung cancer tissues were correlated with neuron-restricted silencing factor and epidermal growth factor receptor. Combined microRNA9 with neuron-restricted silencing factor or epidermal growth factor receptor to predict the prognosis of patients with lung cancer may be more accurate. Conclusion: MicroRNA9 inhibits proliferation and migration of lung squamous cell carcinoma cells by inhibiting neuron-restricted silencing factor/epidermal growth factor receptor axis. MicroRNA9 can be a new prognostic marker and therapeutic target for lung squamous cell carcinoma.

Abstract
Background Circular RNAs (circRNAs) function as essential regulators in diverse human cancers, including hepatocellular carcinoma (HCC). However, the function of circ_0000517 in HCC was unknown. We aimed to explore the roles and mechanisms of circ_0000517 in HCC. Materials and Methods The levels of circ_0000517, RPPH1 mRNA and microRNA-1296-5p (miR-1296-5p) were measured using quantitative real-time polymerase chain reaction (qRT-PCR). The characteristics of circ_0000517 were explored by RNase R digestion and actinomycin D assays. Cell proliferation was evaluated by Cell Counting Kit-8 (CCK-8) and colony formation assays. Cell cycle process and cell apoptosis were analyzed by flow cytometry analysis. The function of circ_0000517 in vivo was explored by a murine xenograft model. The association between miR-1296-5p and circ_0000517 or thioredoxin domain containing 5 (TXNDC5) was determined by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. The protein level of TXNDC5 was detected by Western blot assay. Results Circ_0000517 was upregulated in HCC tissues and cells. Silencing of circ_0000517 suppressed HCC cell viability and colony formation and promoted cell cycle arrest and apoptosis in vitro and hampered tumor growth in vivo. MiR-1296-5p was a target of circ_0000517 and the effects of circ_0000517 silencing on HCC cell viability, cell cycle, colony formation and apoptosis were abolished by miR-1296-5p inhibition. TXNDC5 functioned as a target gene of miR-1296-5p, and the inhibitory effect of miR-1296-5p on HCC cell progression was rescued by TXNDC5 overexpression. Moreover, circ_0000517 promoted TXNDC5 expression via targeting miR-1296-5p. Conclusion Circ_0000517 accelerated HCC progression by upregulating TXNDC5 through sponging miR-1296-5p.

Abstract
Gastric cancer (GC) is one of the most commonly diagnosed malignancies in digestive tract and its underlying molecular mechanism is still not clear, so we aimed to reveal the relationship between GC and UDP-GlcNAc pyrophosphorylase-1 like 1 (UAP1L1). The detection of UAP1L1 expression in GC tumor and normal tissues was accomplished by immunohistochemistry and demonstrated the upregulation of UAP1L1 in GC, which was statistically associated with tumor grade. GC cell models constructed via transfection of UAP1L1-silencing/overexpressing lentiviruses were employed for evaluating the effects of UAP1L1 knockdown/overexpression on GC in vitro and in vivo. The results indicated that UAP1L1 played important role in development of GC through regulating cell proliferation, colony formation, cell apoptosis and cell migration. Subsequently, CDK6 was identified as a potential target in UAP1L1 induced regulation of GC, downregulation of which exhibited similar inhibition effects on GC with UAP1L1. Moreover, it was demonstrated that the promotion of GC by UAP1L1 overexpression could be significantly attenuated or even reversed by simultaneously silencing CDK6. In conclusion, UAP1L1 was reported to be a tumor promotor in the development and progression of GC which may exert its role through regulating CDK6 and may act as a candidate of therapeutic target in treatment.
