Exhibit 99.1

Silexion Therapeutics Reports Positive Preliminary Immunotherapy Findings for SIL204 in

KRAS-Driven Pancreatic Cancer

Preliminary results from a preclinical study demonstrated statistically significant increase in

MHC-I expression following SIL204 treatment in human pancreatic and non-small cell lung

cancer cells harboring a KRAS mutation, supporting potential future evaluation alongside

anti-PD-1 therapies including pembrolizumab (Keytruda®)

  Grand Cayman, Cayman Islands, May 14, 2026 -- Silexion Therapeutics Corp. (NASDAQ: SLXN) ("Silexion" or the "Company"), a clinical-stage biotechnology company pioneering RNA interference (RNAi) therapies for KRAS-driven cancers, today announced
  positive preclinical findings from an ongoing translational immuno-oncology study evaluating its lead candidate, SIL204, in human KRAS-mutated pancreatic cancer cells. The study demonstrated a statistically significant increase in surface expression
  of major histocompatibility complex class I (MHC-I), also known as HLA-ABC, following treatment with SIL204 in human pancreatic cancer cells harboring the KRAS G12R mutation, as measured by flow cytometry.

  “These findings are particularly encouraging because they suggest SIL204 may influence biological pathways involved in the tumors evading the immune cells which are supposed to protect against the tumors, in addition to its previously demonstrated
  direct anti-tumor activity,” said Ilan Hadar, Chairman and Chief Executive Officer of Silexion Therapeutics. “Checkpoint inhibitors have historically shown limited efficacy in pancreatic cancer in part because T cells often fail to adequately
  recognize these tumors. We believe the observed increase in MHC-I expression further supports an additional positive role of SIL204 in the area of immunotherapy which could facilitate positive outcomes in the treatment of pancreatic cancer.”

  MHC-I is essential for enabling cytotoxic T cells to recognize and attack tumor cells. Loss or suppression of MHC-I expression is widely recognized as a key mechanism by which tumors evade immune detection and resist immune-mediated destruction.
  Research has shown that oncogenic KRAS signaling contributes to immune evasion through suppression of antigen presentation and impairment of T-cell recognition pathways in pancreatic cancer and other KRAS-driven tumors.

  Pancreatic cancer remains among the most immunologically resistant solid tumors and has historically demonstrated limited responsiveness to immune checkpoint inhibitor therapies such as anti-PD-1 agents, including pembrolizumab (Keytruda®), outside
  of select biomarker-defined patient populations. By increasing MHC-I expression, SIL204 may help restore immune visibility of KRAS-mutated tumor cells, potentially supporting future therapeutic strategies designed to enhance responsiveness to
  PD-1/PD-L1 blockade.

  Published research has increasingly highlighted the relationship between KRAS signaling, antigen presentation, and immune checkpoint resistance, with multiple recent studies suggesting that reversing KRAS-associated immune suppression may improve
  immune-mediated anti-tumor activity.^1^

  About Silexion Therapeutics
  

Silexion Therapeutics is a pioneering clinical-stage, oncology-focused biotechnology company dedicated to the development of innovative treatments for unsatisfactorily treated solid tumor cancers that have the mutated KRAS oncogene, generally considered to be the most common oncogenic gene driver in human cancers. The Company conducted a Phase 2a clinical trial in its first-generation product, which showed a positive trend in comparison to the control of chemotherapy alone, and is currently advancing its lead, second-generation, product candidate, SIL204, a small interfering RNA (siRNA), towards clinical trials in Israel and the European Union. Silexion is committed to pushing the boundaries of therapeutic advancements in the field of oncology and further developing its lead product candidate for locally advanced pancreatic cancer.
