Background: Although the use of anti-PD-1 antibodies has fundamentally changed traditional cancer treatment, most patients are resistant to anti-PD-1 treatment. Glucocorticoids (GCs) play an important role in tumorigenesis and tumor progression, but the role of endogenous GCs in resistance to anti-PD-1 antibody therapy remains unclear.

Methods: Single cell-derived cell lines (SCDCLs) were generated from a colorectal cancer cell line (CT26) using limiting dilution.

Article Synopsis
  • GII.6 norovirus shows less variation in its major capsid protein VP1 compared to GII.4, which the study investigates across three distinct GII.6 strains.
  • The team expressed VP1 using a recombinant system and analyzed it through various methods, including mass spectrometry, to characterize its molecular properties and binding abilities.
  • Results indicated similar binding capabilities among the different GII.6 strains with observed cross-blocking effects, implying fewer strains may be necessary for effective vaccine development against norovirus.

Ovarian cancer is a malignant tumor originating from the ovary, characterized by its high mortality rate and propensity for recurrence. In some patients, especially those with recurrent cancer, conventional treatments such as surgical resection or standard chemotherapy yield suboptimal results. Consequently, there is an urgent need for novel anti-cancer therapeutic strategies.

The lymphocyte-specific protein tyrosine kinase (LCK) plays a crucial role in both T-cell development and activation. Dysregulation of LCK signaling has been demonstrated to drive the oncogenesis of T-cell acute lymphoblastic leukemia (T-ALL), thus providing a therapeutic target for leukemia treatment. In this study, we introduced a sophisticated virtual screening strategy combined with biological evaluations to discover potent LCK inhibitors.

Background: Although significant advances have been made in the treatment of multiple myeloma (MM), leading to unprecedented response and survival rates among patients, the majority eventually relapse, and a cure remains elusive. This situation is closely related to an incomplete understanding of the immune microenvironment, especially monocytes/macrophages in patients with treatment-naïve MM. The aim of this study was to provide insight into the immune microenvironment, especially monocytes/macrophages, in patients with treatment-naïve MM.

Introduction: To examine the influence of adjuvant chemoradiation therapy (CRT) on survival, stratified by varying numbers and level involved of metastatic lymph nodes in patients with head and neck squamous cell carcinoma (HNSCC).

Methods: Patients who underwent surgery for metastatic, negative margin HNSCC without extranodal extension were retrospectively enrolled and divided into two groups based on adjuvant therapy received: radiotherapy (RT) and CRT. The impact of RT versus CRT, stratified by the number of positive lymph nodes and the level involved, on Disease-Free Survival (DFS) and Overall Survival (OS) was analyzed.

Accumulating evidence has demonstrated that high-risk human papillomaviruses (HR-HPVs) are involved in the etiology of a subset of oropharyngeal squamous cell carcinoma (OPSCC). In this regard, the International Agency for Research on Cancer (IARC) has recommended direct molecular HPV testing. So far, there is no agreement on the most appropriate method for HPV detection on OPSCC formalin-fixed paraffin-embedded (FFPE) materials.

Article Synopsis
  • The study highlights the challenge of lung adenocarcinoma transforming into small cell lung cancer (SCLC) as a resistance mechanism against epidermal growth factor receptor (EGFR) inhibitors like erlotinib.
  • Researchers created preclinical models to investigate this transformation and found that a mechanism involving the transcriptional regulation of EHMT2 and SFRP1 enhances resistance to erlotinib through activation of the WNT/β-catenin pathway.
  • By inhibiting EHMT2, they restored erlotinib sensitivity in transformed cell lines and slowed down resistance in animal models, suggesting a new potential treatment strategy against this form of resistance.

Poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors as maintenance therapy after first-line chemotherapy have improved progression-free survival in women with advanced ovarian cancer; however, not all PARP inhibitors can provide benefit for a biomarker-unselected population. Senaparib is a PARP inhibitor that demonstrated antitumor activity in patients with solid tumors, including ovarian cancer, in phase 1 studies. The multicenter, double-blind, phase 3 trial FLAMES randomized (2:1) 404 females with advanced ovarian cancer (International Federation of Gynecology and Obstetrics stage III-IV) and response to first-line platinum-based chemotherapy to senaparib 100 mg (n = 271) or placebo (n = 133) orally once daily for up to 2 years.
