Despite widespread deregulation of CDK4/6 activity in non-small cell lung cancer (NSCLC), clinical trials with CDK4/6 inhibitor (CDK4/6i) as a monotherapy have shown poor antitumor activity. Preclinical studies indicate that CDK4/6i may collaborate by influencing DNA damage repair pathways during radiotherapy. Since PARP1 expression was also significantly upregulated in NSCLC, we analyzed the efficacy of combining PARP1 and CDK4/6 inhibition in NSCLC models.

Despite the widespread deregulation of CDK4/6 activity in non-small cell lung cancer (NSCLC), the clinical trials with CDK4/6 inhibitors (CDK4/6is) as a monotherapy have shown poor antitumor activity. However, our preclinical studies have revealed a significant potential for CDK4/6is to collaborate by influencing DNA damage repair pathways during radiotherapy. Given the considerable upregulation of PARP1 expression in NSCLC, we analyzed the efficacy of combined PARP and CDK4/6 inhibition in NSCLC models.

Schottky-type self-powered UV photodetectors are promising for next-generation imaging systems. Nevertheless, conventional device fabrication using high-energy metal deposition brings unintentional interface defects, leading to deteriorated device performance and inhomogeneities. Emerging two-dimensional (2D) metallic materials offer an alternative pathway to overcoming such limitations because of their naturally passivated surfaces and the ease of combining with mature bulk semiconductors van der Waals (vdW) integration.

Background: PD-L1 and PD1 mainly focused on melanoma, lung cancer and other tumors, while the related studies on early lymph node metastasis of papillary thyroid carcinoma were rarely reported.

Objective: For elucidating the role of programmed death 1 (PD1)/programmed death ligand 1 (PD-L1) pathway in tumor growth of papillary thyroid carcinoma (PTC).

Methods: Human thyroid cancer cell line and human normal thyroid cell line were obtained and transfected with si-PD1 or pCMV3-PD1 for the construction of PD1 knockdown or overexpression models.

Research on elemental 2D materials has been experiencing a renaissance in the past few years. Of particular interest is tellurium (Te), which possesses many exceptional properties for nanoelectronics, photonics, and beyond. Nevertheless, the lack of a scalable approach for the thickness engineering and the local properties modulation remains a major obstacle to unleashing its full device potential.

Thyroid cancer (TC) is the most common endocrine malignancy. Medullary thyroid carcinoma (MTC) is derived from parathyroid follicle cells (C cells) secrete calcitonin, accounting for approximately 5-10% of all thyroid cancers. The malignancy is between differentiated and undifferentiated thyroid cancer and undifferentiated thyroid cancer and has a relatively poor prognosis.

Triple-negative breast cancer (TNBC) has a poor clinical outcome, due to a lack of actionable therapeutic targets. Herein we define lysosomal acid lipase A (LIPA) as a viable molecular target in TNBC and identify a stereospecific small molecule (ERX-41) that binds LIPA. ERX-41 induces endoplasmic reticulum (ER) stress resulting in cell death, and this effect is on target as evidenced by specific LIPA mutations providing resistance.

The bromodomain and extraterminal (BET) family of chromatin reader proteins bind to acetylated histones and regulate gene expression. The development of BET inhibitors (BETi) has expanded our knowledge of BET protein function beyond transcriptional regulation and has ushered several prostate cancer (PCa) clinical trials. However, BETi as a single agent is not associated with antitumor activity in patients with castration-resistant prostate cancer (CRPC).

Article Synopsis
  • - Neuroendocrine prostate cancer (NEPC) often develops from castration-resistant prostate cancer (CRPC) and is a serious, rapidly progressive disease; understanding the transition mechanisms is essential for better treatment options.
  • - Research shows that sphingosine kinase 1 (SphK1) is significantly implicated in the progression of NEPC and is regulated by the androgen receptor-REST complex, impacting the expression of neuroendocrine markers.
  • - Inhibition of SphK1 was found to effectively reduce NEPC tumor growth and prevent REST protein degradation, suggesting that SphK1 inhibitors could become a targeted therapy for NEPC patients.

Background: Tongfu traditional Chinese medicine (TCM) preparation is a common alternative therapy for clinical treatment of patients with septic gastrointestinal dysfunction. In recent years, a number of randomized controlled trials (RCTs) have been conducted to verify the effectiveness of Tongfu TCM preparation in the treatment of sepsis gastrointestinal dysfunction, but all of them have been small sample studies, and the research conclusions have been controversial. Here, this study conducted a meta-analysis on the clinical efficacy of the treatment of septic gastrointestinal dysfunction with TCM preparation, to produce a more objective and comprehensive systematic review to guide clinical application.

Article Synopsis
  • The androgen receptor (AR) is crucial in prostate cancer, where it adapts to function without androgens in castration-resistant prostate cancer (CRPC), influenced by epigenetic changes and interactions with histone lysine demethylases (KDMs).
  • Longer polyglutamine (polyQ) sequences in the AR-NTD may reduce transcription activity and have protective effects against prostate cancer, though they can also lead to muscular atrophy, with the exact mechanisms still unclear.
  • Research using NMR spectroscopy reveals weak interactions between AR and KDM4A and shows that longer polyQ sequences can enhance liquid-liquid phase separation of AR, suggesting a potential pathway for reducing AR's activity and paving the way for new

A Gram-stain-positive, facultatively anaerobic, non-motile, endospore-forming and rod-shaped bacterium, occurring singly or in pairs, designated TB2019, was isolated from environmental monitoring samples of corridor air collected at the Tianjin Institute for Drug Control, Tianjin Province (PR China). The isolate was able to grow at 15-40 °C (optimum growth at 37 °C), pH 6.0-8.

Neuroendocrine prostate cancer (NEPC) is an aggressive and lethal variant of prostate cancer (PCa), and it remains a diagnostic challenge. Herein we report our findings of using synaptic vesicle glycoprotein 2 isoform A (SV2A) as a promising marker for positron emission tomography (PET) imaging of neuroendocrine differentiation (NED). The bioinformatic analyses revealed an amplified SV2A gene expression in clinical samples of NEPC versus castration-resistant PCa with adenocarcinoma characteristics (CRPC-Adeno).

To explore the correlation between the activating transcription factor 4 (ATF4) and procalcitonin (PCT) expressions combined with mutation and the pathological staging and clinical prognosis of sporadic medullary thyroid carcinoma (SMTC). Fifty cases (tumor tissue) of SMTC diagnosed by clinicopathology were collected and the patients with nodular goiter were selected as normal control. The mutation site was analyzed by detection kit and expressions of PCT and ATF4 in SMTC were analyzed by Western blot and immunohistochemistry.

Epithelial ovarian cancer (EOC) still remains the most lethal gynaecological malignancy in women, despite the recent progress in the management, including surgery and chemotherapy. According to the microarray data of the GSE18520 and GSE54388 datasets, LINC01215 was identified as an upregulated long noncoding RNA (lncRNA) in EOC. Therefore, this study aimed to figure out the involvement of LINC01215 in the progression of EOC.

The study of DNA damage repair response (DDR) in prostate cancer is restricted by the limited number of prostate cancer cell lines and lack of surrogates for heterogeneity in clinical samples. Here, we sought to leverage our experience with patient derived explants (PDEs) cultured ex vivo to study dynamics of DDR in primary tumors following application of clinically relevant doses of ionizing radiation (IR) to tumor cells in their native 3-dimensional microenvironment. We compared DDR dynamics between prostate cancer cell lines, PDEs and xenograft derived explants (XDEs) following treatment with IR (2Gy) either alone or in combination with pharmacological modulators of DDR.
