Breast Cancer

Breast cancer is cancer that forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and lobules (glands that make milk). It occurs in both men and women, although male breast cancer is rare.

HER-2 Positive Breast Cancer

Human epidermal growth factor receptor 2 (HER2) is a gene that can play an important role in the development of some types of breast cancer. This gene is also sometimes referred to as Erc-B2 receptor tyrosine kinase 2 (ERBB2). This gene is involved in the production of HER2 proteins, which are present on breast cells as receptors to control the growth, division, and repair of the cells.

Targeting cyclin-dependent kinases offers new pathways for cancer therapy

Cancer is the second leading cause of death in Germany. In the search for new therapeutic approaches that target the uncontrolled growth of tumor cells, a class of enzymes known as cyclin-dependent kinases (CDKs) has come into focus.

A striking immune cell pattern emerges around a person’s 100th birthday

Single-cell immune profiling found that CD4 cytotoxic T lymphocytes become more abundant around age 100, showing stepwise differentiation and substantial clonal expansion. Ex vivo experiments also revealed cytokine plasticity within individual clones, supporting the hypothesis that these cells adapt to persistent antigens during healthy aging, although their direct role in longevity remains unproven.

Australian researchers uncover a promising new way to tackle triple-negative breast cancer

Australian researchers have uncovered a promising new way to tackle one of the most aggressive forms of breast cancer, raising hopes for more effective treatments to stop the disease from spreading.

Multifunctional nanoplatform addresses three key barriers to effective TNBC immunotherapy

Triple-negative breast cancer (TNBC) is one of the most aggressive and treatment-resistant subtypes of breast cancer, accounting for 15-20% of all cases.

Scientists identify molecule driving one of the deadliest forms of breast cancer

Australian researchers have uncovered a promising new way to tackle one of the most aggressive forms of breast cancer, raising hopes for more effective treatments to stop the disease from spreading.

Scientists uncover safer way to tame cancer cell senescence

Stopping tumor growth is only half the battle. Rather than kill tumor cells, many cancer therapies can only push them into cellular senescence, a state in which cells stop dividing but do not die. These "undead" cells will continue to release signals that reshape the tumor environment.

Multi-organ chip uncovers key mechanisms behind cancer metastasis

Cancer spreading beyond the primary tumor – a process known as metastasis – is responsible for at least two-thirds of cancer deaths.

Special journal issue highlights precision prevention in cancer epidemiology

Cancer epidemiology is not merely about counting cases; it is a dynamic field that informs screening policies, resource allocation, and clinical trial design.

Red blood cells inspire next-generation therapeutic nanocarriers

Red blood cells serve as the foundation for nanocarriers that show promise in a new study as effective and efficient vehicles for gene therapy, tumor targeting and other medical treatments.

Dual-action compounds show promise against aggressive cancer and infections

Cancer patients often face more than the disease itself. Their treatment is frequently complicated by infections and other health conditions, meaning they may need to take several different medications at once.

Preoperative combination therapy improves head and neck cancer outcomes

Patients with head and neck cancer who received chemotherapy in addition to immunotherapy before surgery had a significantly reduced tumor size at the time of operation than patients who received immunotherapy alone.

'Locked' cancer therapeutic safely shrinks breast tumors in mice

Although there are many cancer treatments available today that effectively eliminate abnormal cells, these therapies may also damage healthy cells, leading to unwanted side effects.

Mitochondrial gene RTN4IP1 drives triple-negative breast cancer metastasis

Triple-negative breast cancer accounts for approximately 15% of all breast cancer cases. It is characterized by the absence of estrogen receptor, progesterone receptor, and HER2 expression, rendering it insensitive to conventional endocrine and targeted therapies.
